Fruit growing
and viticulture of South Russia
Results of an estimation of stability of differ-ent apple varieties maturing are resulted in action of weather stress to a spring frost. Varietals characteristics of sensitivity to frost pistils and anthers, and the age of generative structure are revealed.
Adaptive features of genotypes pear varieties to specific agroecological conditions are re-vealed. The analysis and selection of the va-rieties most adapted to is carried out is soil-environmental conditions a steppe zone, the grades possessing raised winter hardiness, good commodity and taste qualities of fruits, are recommended by reserved growth of a tree for production test.
Grades of sweet cherry resistant to cracking, such as Smuglyanka, Volshebnica, Zemly-achka, Yantarnaya, Drogana zheltaya and others are allocated as a result of studying of stability of fruit to cracking in natural condition and by laboratory method.
SYRIAN HIBISCUS ADAPTIVE CAPACITY AT ITS INTRODUCTION IN THE CENTRAL SUBZONE OF THE KRASNODAR REGION
We consider the adaptive response of Syrian hibiscus to the arid conditions in the central subzone of Krasnodar region. A preliminary assessment of adaptive capacity of introduced varieties of hibiscus is given, cultivars ranging according to the degree of drought resistance is conducted.
Laboratory and field data on studying of physiological and biochemical features of resistance to drought of different chromosomal apple-tree forms are presented.
