With more and more attention being given to the breeding of new varieties suitable to particular climatic conditions, knowledge as to the relative times of blossoming and leafing of domestic and foreign varieties of peaches and nectarines is of growing interest . As a part of the program of evaluating plant introductions at the United States Plant Introduction Garden at Chico, California, the annual recording of various phenological characteristics has been an important phase of the work. This paper pre- sents the portion of these data which relate to the times of full bloom and of first foliation of the several hundred variety and seedling peaches and nectarines in the Chico collection,, The particulars on first foliation are additional to those supplied by Ackerman (l) . Since a representative analysis of blossoming and leafing data showed a close correlation, only blossoming data has been utilized in the general discussion.

Procedure.

The data from, which this paper was compiled cover 1959, 1950, 1951 and 1953 , that for 1952 being too sparse to include. In general, trees were considered to have reached full bloom when approximately ?5 percent of the blossoms had Gpenedo The time of first leaf emergence was determined as that time at which a reasonable proportion of terminal leaves over the tree as a whole had grown to approximately one-fourth to one-half inch in length.

Temperatures in degrees Fahrenheit reported here are those recorded from Standard Weather Bureau maximum and minimum thermometers located in a stand- ard weather shelter within approximately one-half mile of the farthest trees.

The number of hours at or below 55 degrees F was computed from charts of a recording thermograph located in the same shelter.

The soil varies from a vina sandy loam to a vina Icam. An alluvial soil, it was transported from the hills and mountains to the east and ranges in depth from eight to twelve feet.

Occasional variations in the times of full bloom and first leafing were noted among some asexual propagations of individual clones. In most cases these were in widely separated locations. Trees showing wide variations and sus- pected of being affected by physical injury or disease were removed from the list. Differences in minimum temperatures of as much as 5 degrees F are known to occur between different sections of the Plant Garden. Temperature, rootstock, soil or moisture influences may account for most of these variations#

The introductions listed in the tables include named varieties* unnamed seed- lings and the asexual progeny of some of the latter. Each is identified by its Plant Introduction number and location in the orchard. Names of foreign varieties are those carried in the Plant Introduction Inventory* but since variety authenticity has not been established in some cases* they do not neces- sarily assume trueness to name. Nectarines are identified by the abbreviation (nect.) following the variety name or seedling. All clones not so designated are peaches.

Seed introductions are identified in the tables bjr the numeral two (2) after the name of the source $ all others were received as plants or scions. Source as used in this paper refers to the country from which the material was introduced^ it may or may not have originated there. Section o. province within a country is given where it is felt this might be useful. Seedlings with the same P.I. number are members of a population resulting from a lot of seed introduced under that number. Where seedlings have been asexually reproduced, the parent tree* when still present, is listed first* followed by its vegetative progeny. These latter are further identified by adding the parent tree location. New P.I. numbers are assigned to outstanding seedlings so as to distinguish them more easily from other members of the population. These are considered as selected seedlings and are so indicated by the numeral three (3) after the seedling.

Since the relations of the time of full bloom and also first leafing of the vari- ous clones to each other* rather than the actual dates* are of primary interest, index numbers have been substituted for dates. These index numbers are consecu- tive numbers representing the consecutive days of the year beginning with January 1 as suggested by Bradford 3 • An index thus represents the same month and day in each of the four years involved (191+9* 1950*, 1951 and 1953).

Table 1 lists a small group of the more popular peaches* according to Dorsey (5)* and also a few of the nectarines grown in the peach-growing districts of the coun- try. These were selected as known standards for comparison with the large number of relatively unknown clones listed in Table 2„

In Table 2 a large collection of foreign and domestic peaches and nectarines are arranged in sequence of earliness of full, bloom based upon indexes representing the average date of full bloom of the four years considered in this paper.

Individual yearly indexes representing the time of full bloom and also first leaf are listed to indicate seasonal variation. Also included are the numbers of hours of temperature at or below b5 degrees F from November 1 to full bloom for each year.

Table 3 contains a summary of the weather conditions prevailing at Chico from November 1 until April 10 during the four years of this study. Included are the weekly averages of daily maximum and minimum temperatures and an accumulative sum- mation of precipitation along with the number of hours at which the temperature was at or below 1;5 degrees F.

DISCUSSION.

The winters at Chico are rather mild as compared with those in many of the peach- growing areas of the country, yet only occasionally is there insufficient chilling to cause noticeable delayed dormancy in peaches and nectarines and rarely are such conditions serious enough to impair fruiting markedly.

Hutchins* cited by Weinberger (?) * stated that for Georgia conditions 1000 accumu- lated hours of U5 degrees F or below is sufficient to break the rest period of most

varieties of' peaches. Weinberger in addition suggested that at Fort Valley, Georgia, if a variety had not had its chilling requirement satisfied by February 15, it tended to suffer from prolonged dormancy even though additional chilling occurred later. In this study, 1000 hours was reached considerably before this date in 1 9h9 and 1950. However, in 1951 this accumulated amount was not reached until February 22 and in

1953 it was reached on February 15, as shown in Table 3.

The dormant season of 19U8-U9 was unusually cold and rather dry. The first three weeks in March were, however, cloudy and wet, there being seventeen days of rain and only two clear days during this period. Although there appeared to be suffic- ient cold to break dormancy, the continued low temperatures and cloudy, wet weather held back the normally early “blossoming clones.

The data in Fig. I indicate that blossoming in 1 9h9 was pushed toward what is con- sidered the latter part of the season. This resulted in a diminished range (only 26 days) between the time of full bloom of the earliest clone and that of the latest as compared with ranges of 1±1, 5l and 55 days for 1950, 1951 and 1953, respectively. Bradford (3), Yameli (10, 11), Pearce and Preston (6) and others, have noted that the progressive development of fruit buds toward flowering is conditioned by hours of warm temperature during the dormant season as well as by those below U5 degrees F. In 1949 the first occurrence of full bloom was on March 15, when there had been 139b hours above b$ degrees Fj in 1950 it took place on February 2b with lli.ll; hours; in 1951 on February 15 with I6I4.O hours and in 1953 on February 8 with II4.67 hours. Thus, it would appear that even though the cold requirements had been met, the heat require- ments were not fulfilled until rather late in 19U9, and this deficiency of heat con- tributed to the lateness of blossoming that year.

Tine 1949-50 season was one of alternating periods of rather warm and relatively cold weather for Chico. November of 1949, with its mean, maximum of 71° 2 degrees F and mean minimum of 1*2 „ 6 degrees F, was the warmest in the fifteen years from 19l|0 to

1954 ° Twenty-two of the thirty days of that month were recorded as clear and sunny. December 1 9h9* on the other hand, averaged as one of the coldest Decembers during this same period, the temperature remaining fairly uniform throughout the month.

There were, however, four days, December I5 2, 8 and 28, in which maximums of 60 degrees to 66 degrees F were recorded. Sixteen of the thirty-one days were clear and sunny. The first half of January was likewise uniformly cool. Up to January 16 there had been 960 hours of degrees F or below, of which 7%h had occurred since December 6. This 960 hours compared with 1086, 680 and 808 hours for 19l;8~li9,

1950-51 and 1952-53, respectively. For the week of January 17 to 23 there was, however, a sudden rise in temperature. Because of predominantly cloudy weather, the maximum temperature reached only 61+ degrees F but the minimum nevp” *T°nt below bk degrees F. Mean temperature for this week was 55° 7 degrees F, as compared with 37° 9 degrees F for the other three weeks and lfL.9 degrees F for the entire month. From January 2b on through February ll|, the temperatures were again comparatively cool.

The weather then warmed up considerably and continued to be rather mild though varia- ble throughout March.

It would appear that the 1295 hours of I4.5 degrees F or below that had accumulated by February 13, 1950 (Table 3) should have been sufficient to meet the chilling require- ments of almost all the peaches that year. However, as shown by Fig. 1, the blossom- ing pattern for 19H9-50 turned out to be rather peculiar as compared with that of the other three years. Because of the early accumulations of hours of cold followed by the comparatively warmer weather after February ll;, the early and mid-season types

-V

came into bloom rather early, but the later blossoming types were pushed consider- ably beyond their anticipated time of bloom. Bennett (2) in an experiment with pears found that alternating periods of cold and warm temperatures were not as elective in leaking dormancy of leaf buds as continued cold without interrup- tion, even though t-he total cumulative exposure to cold was the same. In an exoer- iment with the peach variety Sullivan Elberta, Weinberger (3) found certain periods at which delay in breaking dormancy of peach buds was most susceptible to higher temperatures. He concluded that high temperatures in November and December had more effect on prolonging dormancy for this variety than in January, but that December was- the most critical month for Fort Valley, Georgia, conditions.

Thus, according to the views of Bennett (2) and of Weinberger (7, 8) the warmer than usual November 19h9 and the week of warm weather in January 1950 would tend to retard clones with longer chilling requirements. For those requiring less chilling, the colder than usual December and early January would tend to offset the November warmth, while the warm, break in January would tend to force into bloom those whose dormancy was broken. That this appears to be something of the case is shown in Fig. 1. Clones with low chilling requirements began to bloom a short time after the weather warned in mid-February . Even the greater bulk of the collection requiring moderate chilling had their blooming period pushed ahead. On the other hand, clones requiring the most chilling tended to bloom later in relation to the main group in 1950 than in any of the other years. Tills is evidenced by the prolonged spread of the right side of the curve for the 1 950 blossoming season.

There is an interesting break in the 1950 curve, about March 22, for which no ready explanation is evident. This break had its inception at a time when daytime tempera- tures were approximately 63 degrees- to 67 degrees F and those at night 45 degrees to 47 degrees F. There was some cloudiness but little precipitation. Colder tempera- tures and rain did not occur until the frequency rise was again well under way.

The months of November and December 1950 were unusually warm. By January 2, 1951 only 4.21 hours at or below k? degrees F had accumulated as compared with 801, 651 and 674 hours for the same dates in 1949, 1950 and 1953 (Table 3). The rainfall for November was rather high and during the last two weeks of December, almost all of January and the first half of February there were much cloudiness and heavy fog.

Only a fair amount of cold occurred in January, there being 336 hours at or below 45 degrees F from January 2 to 30 as compared with 5?3, 466 and 204 hours for the same period in 1949, 1950 and 1953, respectively.

Although this was a relatively warm winter no distinct abnormalities in blossoming or leafing were noted in 1951- In contrast, delayed dormancy was very apparent among some clones in 1953 even though the total number ox hours at or below 45 degrees F was slightly higher in 1953 than in 1951* Weldon (9), Chandler et al (4) and others have noted the beneficial effects of various kinds of shading in breaking the rest period of plants. Thus, in spite of the warm weather of November and Decem- ber, the dense fog and cloudy weather of the 1950-51 season were apparently an impor- tant factor in alleviating whatever temperature deficiencies there may have been that year.

November and the first three weeks of December 1952 were rather cool. By December 19 there had been the largest accumulation of hours at or below 45 degrees F in any of the four years, there being 536 hours by that date as compared with. 397 and i

hours in 19l'3. 19)-9 and 1950, respectively (Table 3). Although the accumulations

-5-

between November 1 and December 19 are strikingly similar for 19U8 and 1952, the similarity ends there. From December 19 on through the early weeks of 1953 there was much warm weather resulting in a greatly reduced rate of increase in accumulation of hours at or below ii5 degrees F. Thus a comparison shows 636,

67 hi 762 and 878 hours on December 265 1952, January 25 16 and 30, 1953, and 668, 801, 1086 and 1379 hours for these same dates in 19l|8-l|9. This premature rise in temperature in the early part of 1953 brought about exceptionally early blossoming of peaches whose chilling requirements were met by the earlier cold (Fig. l). These observations agree with those of Weinberger (7) that inten- sive early winter chilling hastened the rest-breaking processes. Thus, in this case clones with lower chilling requirements came into early bloom because their rest period was broken early and subsequently there was a sufficient accumula- tion of heat units to push them into bloom as suggested by Bradford (3),

Pearce and Preston (6), Yamell (10, 11) and others.

Sven among the types with high chilling requirements the effect of the over-all warn winter in causing delayed dormancy was, with one exception, not readily ob- served. The exception occurred among some peach introductions from China numbered P.Io 101663 through 101689 (Table 2). Although rather obvious, the delay was not observed until after the time of first leaf. Actually, foliation in this group developed to a stage slightly beyond first leaf and then remained visibly unchanged for about three weeks before growth again resumed and full leaf was eventually reached.

The primary objective of this paper was to make available a list of the large number of foreign and domestic peaches and nectarines in the Chico collection, along with as many data as possible pertaining directly to individual and collective reactions to climatic conditions in this area. This study disclosed that the phenological re- sponses of blossoming and leafing of this collection are in accord with those pub- lished by others working with more limited plant collections. Different clones vary considerably in heat requirements necessary for blossoming as well as in chill- ing requirements to break dormancy. Yarnell (11) stated that these requirements' for heat and for cold are determined by distinct genes. It is hoped that the rather detailed study of weather conditions during the four seasons and the plant responses to these conditions may present a better picture of what the plant breeder may expect from foreign introduction material.

Footnotes Evaluation of many of the introductions listed in this paper is about complete. Space limitations call for their removal during the winter of 1956. Readers are urged to request of L. E. Joley at the U. S. Plant Introduction Garden, Chico, California, scions or budwood of ary that may be of interest.
