Apple tree varieties on clonal rootstock 54–118 were studied in terms of frost resistance and drought resistance. The purpose of the research is to study the resistance to frost and drought of apple tree varieties of VNIISPK breeding on clonal rootstock 54–118. Climatic conditions affect fruit trees and further lead to a sharp decrease in the fruit productivity and commercial qualities. The problem study of resistance to various extreme growing conditions (including frost, low temperatures, drought and high temperatures) is relevant. A variety that has a high resistance under various adverse weather conditions is considered as winter-hardy, i.e. shows all the components of frost resistance. The study of the main components of winter hardiness (I, III, IV) showed that apple tree varieties (Orlik, Venyaminovskoye, Sinap Orlovsky, Veteran, Svezhest, Rozhdestvenskoye, Bolotovskoye - of the FSBSI VNIISPK breeding; Antonovka obyknovennaya - of local selection on clonal rootstock 54–118) had minor bud damage. The bark and wood were not damaged. When studying the total water content of leaf tissues during the growing season, all varieties on the clonal rootstock 54–118 were assigned to the average level of hydration. In laboratory conditions, over the years of research, the varieties had a high indicator of the ability to restore water content of leaf tissues after drought. On the clonal rootstock 54–118 the apple tree varieties are able to withstand thaws, spring frosts, droughts and dry winds.

“…Some researchers attribute the mechanism of plants drought adaptation not to the total water content in leaves, but to its fractional composition -the amount of free and inherent water. Free water provides the course intensity of a number of physiological processes, and the inherent water contributes to increasing the resistance of plants to abiotic stressors [2,4,7,19,22,23].…”

“…Physiological-biochemical research methods are promising methods in assessing adaptability to drought and elevated temperature [5,6]. In some fruit and berry crops (apple trees, grapes, currants) during the period of drought there were changes in the water balance, morphological leaf structure: decrease in the overall leaf water content, inherent water increase and reduction of leaf lamina area [3,4,7,8].…”

Physiological and morphological studies of red Russian and foreign breeding red currant varieties were carried out for establishing intensive plantings and introduction. Varieties Dana, Niva, Vika, Hollandische Rote are yielding, highly resistant and promising for introduction and industrial cultivation, during dry periods they are able to regulate metabolism through changing indicators of water balance (water deficit, fractional composition of water) and photosynthetic apparatus of leaves (leaf lamina area). Using Natali, Shchedraya and Jonkheer Van Tets varieties in production is possible with application of artificial irrigation. Selyanochka variety is most affected by weather conditions and is recommended to be grown in temperate climate area. Physiological and morphological methods of research allow to diagnose the genotypes resistance of garden crops to growing period abiotic factors at the early stages of plant development, they are confirmed by field observations and are promising in diagnosis for establishing intensive gardens and berry-fields.

“…Поэтому водоудерживающая способность тканей является одним из диагностических показателей адаптации растений к засухе. Российские и зарубежные ученые в своих работах отмечали, что от нее зависит скорость расхода воды листьями, величина общей оводненности и ее потери в зависимости от напряженности фактора воздействия и сортовой специфики [7][8][9][10]. Скорость отдачи воды используется как показатель засухоустойчивости, поскольку растения с высокой водоудерживающей способностью, по мнению ряда исследователей, характеризуются и повышенной устойчивостью к высоким положительным температурам [8].…”

“…В то же время, у растений сортов Оротак, Джуси Фрут и Фанал независимо от гидротермических условий показатели были ежегодно стабильными (рисунок 1). Полученные нами данные по динамике оводненности и её сортовой специфике подтверждают исследования ряда ученых о том, что у яблони, груши, смородины существует значительное варьирование показателей оводненности листового аппарата в зависимости от условий года и биологических особенностей сортов [5,6,10].…”

There is an abnormal increase in average summer temperature in the southern region (Krasnodar Territory). This, more than ever, actualizes the problem of identifying drought-resistant varieties of fruit crops, including cherry. The purpose of this research was to study the physiological indicators of water regime: loss of water, water-holding capacity, leaf water content, abscisic acid content in leaves of different varieties of Cerasus vulgaris Mill., which determine resistance to temperature stress, as well as to identify the most drought-tolerant varieties to optimize the range of varieties for the south of our country. The studies were carried out in 2018–2019 in the Prikuban fruit-growing zone of the Krasnodar Territory. Sixteen varieties of Cerasus vulgaris Mill. were the objects of the research. Varieties ʻKrasnodarskaya sladkayaʼ and ʻKazachkaʼ served as a control. Planting schemes – 6 × 4 m and 5 × 3 m. Soil – chernozems leached. pHwater – 6.8–7.22. Humus content – 3.47 %. In summer, meteorological conditions were characterized by an abnormal temperature rise (up to 39.3 ℃) and extended periods of drought. Studying of water regime was carried out according to the modified methodology of M. D. Kushnerenko using the gravimetric method. In laboratory experiments, we used the capillary electrophoresis “Kapel 104 P” (power supply with a positive polarity; equipped with a photometric detector; set wavelength – 254 nm). In the course of the research, we revealed that the water content in cherry leaves during the period of the adverse draught (in July) was 57.9 %; in the context of studied cherry varieties, it varied insignificantly (Cv = 4.4 %). For two hours, the loss of water by the leaf apparatus was not high – from 6.5 % to 11.9 % with a low coefficient of variation by varieties (Cv = 1.9 %). The water-holding capacity of leaf tissues was 19.6 %, the range of variability of which was insignificant by varieties (Cv = 18.0–24.2 %). The average content of abscisic acid in cherry leaves was 4.3 mg/kg and varied depending on the studied cherry varieties within the range of 1.5–14.2 mg/kg. According to the complex of physiological indicators of the water regime (low water loss (6.5–7.9 %), high water-holding capacity (19.4–24.2 %) and leaf water content (58.1–61.9 %), as well as increased abscisic acids content (11.0–14.2 mg/kg)), such cherry varieties/cultivars as ʻDuke Ivanovnaʼ, ʻDuke Khodosaʼ, ʻFeyaʼ, ʻMolodezhnayaʼ and ʻErdi Botermoʼ were classified as highly drought-resistant. They are recommended for expanding the range of adaptive cherry varieties/cultivars in the southern part of Russia.
