The article presents the results of the pomological study of the cultivars of apricot derived from of Shalakh variety. The results of the analysis showed the presence of prevailing features of transmitted offspring from the desired variety. The best inheritability of the features of the Shalakh was traits of symmetry of fruit and stone (100%), form hole shape of stone (100%), shape of apex of stone (100%), keel character of stone (100%), depth of stalk cavity of fruit (88.9%), shape of stone base (88.9%), stone thickness (77.8%), lateral ribs type of stone (77.8%). The oblongness of the fruit and stone has poor or almost is not transmitted to the offspring from the Shalakh.

Some morphological traits of the fruit and apricot stone of Dagestan origin at the different ripening periods

2020

The paper presents the results of a comparative study of the cultivated and wild-growing apricot of Dagestan origin according to the morphological characteristics of the fruit and stone at different ripening periods. The pomological evaluation showed that the shape index of the fruit changes by one gradation regardless of the origin of the genotype, while the shape of the stone does not change and remains constant for all genotypes. For example, the fruit of the Kamil cultivar has an ovate shape at an early ripening period, and a circular one at late ripening. During ripening, the weight of the fruit doubles (1.8–2.6 times), while the ratio of stone mass to the weight of the fruit decreases (1.8–2.5 times). For cultivars and wild-growing forms, differences in the change in the linear dimensions and mass of the stone at different maturation periods were noted. The morphological characteristics of the fruit and stone in terms of the coefficient of variation (CV) vary more at the later stages of ripening, and in general are higher in cultivars than in wild plants, and the endocarp varies less than the fruit, at all periods of ripening.

“…[13]. Wild apricot is distributed in the valleys of the rivers Avarian Kojsu, Andijsky Kojsu, Kazikumuhsky Kojsu and Kara-Kojsu, at altitudes of 350-1500 m above sea level, occasionally (singularly) along the southern slopes up to 1900 m, preferring limestone slopes of various exposures [14]. At the same time, local varieties, including the discovered valuable natural forms, are of significant scientific interest, both in the analytical and in the purposeful breeding process.…”

Dynamics of the growth processes of Prunus armeniaca L. seedlings in the conditions of Inner Mountain Dagestan

Osmanov

2020

The paper presents the results of assessing the dynamics of growth processes 364 seedlings of 16 apricot samples under conditions of a critical altitude level for them in Dagestan (1900 m). A comparative study of apricot samples showed that during the growing season, annual seedlings form a small height of the main shoot (18.7–28.7 cm), subramose (0.4–2.7) and leafiness (14.7–23.6). Analysis of the relative dynamics of shoot growth showed that the maximum growth was observed in May-June (62.8–95.7%) and low in July-September (1.0–24.5%). A reliable correlation was established between the relative growth of the studied samples and their winter hardiness, namely, the higher the relative increase in July-September, the lower the winter hardiness. The correlation in MayJune was -0.77**, and in July and September 0.62* and 0.64 **, respectively. The experiment showed the information content of studying the growth of shoot length as a diagnostic feature in assessing the winter hardiness of apricot seedlings in the mountainous conditions of Dagestan.
