How to Prune and Thin Your Peach Tree This Spring
Brazilian peach breeding programs have been established to improve peach [Prunus persica L. Batsch] production, yield consistency, quality, and disease resistance. Every year several genotypes are selected and their traits must be assessed.
This study aimed to evaluate adaptability and stability of fruit set and production of peach genotypes in a subtropical climate, using the GGE biplot methodology.
The genotypes 'Conserva ', 'Rubimel', 'Kampai', 'Tropic Beauty', and 'Cascata ' had the greatest adaptability and stability for fruit set. The GGE-biplot methodology classified the peach tree genotypes with regard to adaptability and stability of fruit set and production. Brazilian peach breeding programs have been established to improve peach [ Prunus persica L. The spread of commercial peaches [ Prunus persica L.
Batsch] to subtropical and tropical regions has increased rapidly in recent years. This increase is especially noticeable in Brazil, where climatic conditions are highly variable. Subtropical humid zones, located in Southern Brazil, have hot, humid, rainy summers that favor disease development. Furthermore, inconsistent winter dormancy conditions, caused by conflicting air masses of tropical and polar origins, result in both insufficient chill accumulation in some years or sites and a late frost risk during bloom.
The cultivars better adapted to Brazil have low chilling requirements 0 to chilling hours below 7. Therefore, Brazilian peach breeding programs have been introduced designed to improve peach production, yield consistency, quality, and disease resistance Raseira et al. Mild winters with a wider range of temperature conditions during dormancy have been related to several physiological and biological disturbances leading to the appearance of a high level of floral anomalies and flower bud drops, which compromise blooming Lamp et al.
Chilling, when insufficient, poses problems for trees that have to overcome endodormancy and can consequently result in low fruit set and yield for genotypes not suitably adapted.
In this sense, knowledge of the adaptability and stability of fruit set and production in different locations or years is crucial when the objective is to increase crop production potential. Thus, the aim of this work was to evaluate adaptability and stability for fruit set and production of peach genotypes in a subtropical climate using the GGE biplot methodology. Temperatures below 7. Each genotype was represented by three plants.
The experiment used a completely randomized design. Five one-year-old shoots, 25 to 30 cm long, per plant were randomly selected from around the canopy for fruit set. The trees were five years old inThe orchard received standard fungicide and insecticide sprays, pruning and fertilization, similar to the treatments used in commercial orchards. No chemical means were used to break dormancy. The evaluation of fruit set was carried out between 30 and 35 days after full bloom.
The evaluation of tree production was made by multiplying the total number of fruits by the average fruit weight of each genotype and the results were expressed in kg per tree.For fruit numbering, all fruits in three trees of each genotype were counted close to harvest. The weight average was measured collecting 30 fruits at the beginning, at full and at the end of harvest totaling 90 fruits per genotype per year.
To analyze the adaptability and stability of fruit set and tree production, the GGE genotype main effect plus genotype by environment interaction effect biplot methodology Yan and Rajcan, was used, based on the following model:. The two main axes represent most of the variation in the data, considering the environment effect as fixed, i.
In each graph, a polygon was constructed to join the points that represent the most distant genotypes in relation to the origin of the axes. Later, perpendicular lines were designed for each polygon edge passing through the origin, separating it into sections.
A PC1 value near the origin indicates that the genotypes have means close to the general mean represented by the origin of the lines. As the value becomes more distant and to the right of the origin, the greater the value of the variable can be considered and the more adapted the genotypes in this case, for fruit set or tree production. A PC2 value near zero indicates more stable genotypes. The graphical biplot may also identify the ideal environment year , indicated by a year that has a high value for PC1 and a value near zero for PC2 Yan and Kang,The normality and homogeneity of the data were checked by Shapiro-Wilk and Bartlett's tests, respectively.
Chilling accumulation was observed from the end of May until mid-June, when frost occurred. After this, a tendency towards heat accumulation was observed. Although not intense, the chilling was continuous, without abrupt temperature fluctuations no periods of heat. Dangerous frosts were observed at the end of July Figure 1.
In this year, chilling accumulation was observed only from mid- July, with the occurrence of no dangerous frost Figure 1. During the three growing seasons, the response of fruit set and production differed among genotypes, which indicates the existence of a genotype-environment interaction. This interaction is expressed by the GGE biplot model. The SREG sites regression obtained by genotype and genotype-environment interaction GGE biplot was performed to provide an easy visualization of the complete data set in a reduced dimension plot.
In the GGE biplot model the effects of genotype and genotype-environment interaction are multiplicative. The PC1 was directly connected to the genotypic effect allowing for almost perfect correlation between the variable analyzed and the PC1 score.
For fruit set, the year was the environment that could be considered the closest to the ideal because it was the most stable near the PC2 axis origin and promoted good fruit set Table 2. The years and were the most unstable far from the PC2 axis origin with poor fruit set Table 2 , which allowed for better discrimination among the genotypes Figure 2.
The principal sectors grouped the years and , and the following genotypes: 'Conserva ' 22 , 'Cascata ' 18 , 'Rubimel' 2 , 'Tropic Beauty' 1 , 'Cascata ' 15 ; 'Conserva ' 27 , 'Conserva ' 25 and especially 'Conserva ' 22 with the greatest fruit set.
For tree production, the year was the most stable near the PC2 axis origin and promoted reasonable production for most of the genotypes, with an average ofThe years and were the most unstable far from the PC2 axis origin , which allowed for better discrimination among the genotypes, being the year with the greatest average production in the years studied Figure 3 and Table 2.
The other sector grouped the year and the genotypes 'Conserva ' 25 , 'Atenas' 10 , 'Tropic Beauty' 1 , 'Cascata ' 18 , 'Conserva ' 27 and 'Conserva 'The first had the greatest chilling requirement among the genotypes studied, and the second had serious problems with floral bud abortion data not shown. Dangerous frosts after fruit set, as observed in Figure 1 , were the cause of instability and low production observed in this year Figure 3 and Table 2.
In Southern Brazil, the occurrence of frost usually coincides with the period of flowering and fruit development Raseira et al. On the other hand, chilling negation by high temperatures is a cause of low budbreak in peach Richardson et al. In , despite having the same chill accumulation as in Figure 1 , it occurred later, and was not as effective in overcoming dormancy of flower buds, with heat accumulation during pre-blooming period, from the beginning of to mid July Figure 1 , causing lower fruit set than in , but more than in Table 2.
Frost in late July was not dangerous, but caused fruit drop in a few genotypes that had already reached full bloom. The heat, during pre-blooming, and the frost, after blooming, were responsible for instability observed in both fruit set and production in Figure 2 and Figure 3.
Rodrigo and Herrero observed that an increase in temperature accelerated flower bud development causing a hastening in flowering time and following hand-pollination, reduced fruit set in apricot. At anthesis, flowers that had developed in warmer conditions weighed less and showed less development of the pistil than control flowers. Ensuring good fruit set is important, but this alone is not sufficient for good production. Production is a function of orchard density, flower density, index of fruit set and fruit size for all species, varieties and climatic conditions Dennis Jr.
Excellent yields were obtained when there is good fruit set and fruit size. However, after fruit set, the number of fruits per plant is generally standardized by thinning practices; a fact that occurred in this experiment, therefore, from the thinning, production will be defined by fruit size of each genotype.
Yamaguchi et al. In sweet cherry, differences in mesocarp thickness were correlated with both cell number and cell size Yamaguchi et al. Mesocarp cell number was remarkably stable and virtually unaffected by the environment as neither growing location nor physiological factors that reduced final fruit size altered the cell numbers.
Cell length was influenced by the environment, indicating that cultural practices that maximize mesocarp cell size should be used to achieve a fruit size potential of the cultivar Olmstead et al. Other related genotype-dependent floral biology factors affect fruiting in temperate fruit species, such as flower bud production, flower production, flower bud drop, flowering time, percentage pollen germination, height difference between the stigma and the superior plane of the anthers, percentage of aborted pistils, autogamy level, fruit set and fruit production Ruiz and Egea,Some of these characteristics may have contributed to the reduction of the average fruit set and production in the genotypes studied, even those genotypes that had sufficient chilling accumulation.
These causes should be elucidated in future work. In conclusion, genotypes 'Conserva ', 'Rubimel', 'Kampai', 'Tropic Beauty' and 'Cascata ' demonstrated the greatest adaptability and stability for fruit set. The GGE-biplot methodology was successful in classifying peach tree genotypes with regard to adaptability and stability of fruit set and production.

Do you have a peach tree that only fruits every other year? Perhaps you get a lot of tiny peaches?
Beyond the typical flowers and plants, many gardeners are looking to grow something this spring that will allow them to really enjoy the fruits of their labor. Planting fruit trees might seem daunting, but for many who have tried, it's well worth the effort. Mount Washington resident Scott Smith got "hooked" on planting fruit trees 15 years ago, and now has over on his acre of land — from apple and peach to kiwi and jujubes. Smith has also worked with the Baltimore Orchard Project, a division of the nonprofit Civic Works that works to strengthen communities through planting orchards. But planting fruit trees brings trials as well as triumphs.
O ne of the more common questions I get at this time of year when everything is dormant is when, and how, to prune various fruiting plants, like peaches, blackberries, figs and blueberries. In general, January and February is an ideal time train and trim most of our orchard fruits. Each type of fruit is trained and maintained differently, and so it is helpful to know some general guidelines for what you are growing.
