Стабильность развития смородинно-крыжовникового гибрида Jo'sta в условиях интродукции в Красноярском крае

The study is devoted to the question of the as-sessment of stability of development of Jośta cur-rant-gooseberry hybrid growing in the territory of Emelyanovsky and Berezovsky districts of Krasno-yarsk Region. The research objective was in carry-ing out the assessment of size of the fluctuating asymmetry of the leaf plate of Jośta currant-gooseberry hybrid as the factor of stability of devel-opment of the plant in the conditions of introduction in the midland of Krasnoyarsk Region. The as-sessment of development stability of plants and the size of fluctuating asymmetry of a leaf plate was carried out according to V.M. Zakharov's technique. The measurement of the following indicators of the fluctuating asymmetry of leaf plates of a birch and Jośta currant-gooseberry hybrid were carried out: the width of the left and right halves of a leaf; the distance from the basis to the end of the vein of the second order, the second from the leaf basis; the distance between the bases of the first and second veins of the second order; the distance between the ends of the first and second veins of the second order; the corner between the main vein and the second from the leaf basis a vein of the second order. The assessment of the state of environment of Emelyanovsky and Berezovsky districts of Kras-noyarsk Region was carried out. It was established that the variation degree between the bases of the first and second veins of the second order of a leaf plate of a birch is the most sensitive morphological feature to environment conditions. The study of the fluctuating asymmetry of Jośta currant-gooseberry hybrid showed higher extent of stability of devel-opment violation of the plants growing in the territo-ry of Berezovsky district of Krasnoyarsk Region. This fact can be explained by the impact on plants of emissions of thermal power plants and industrial enterprises located on the right bank of Krasno-yarsk owing to their movement with air masses. The possibility of successful cultivation of Jośta currant-gooseberry hybrid in the territory of Emelyanovsky district of Krasnoyarsk Region has been noted.
