INFLUECE OF CONDITIONS OF THE REGION ON THE FORMATION OF PHYTOCOENOSIS STEVIA HONEY

Abstract

On the basis of the conducted researches: level of the yield of green mass and dry matter of stevia honey. Defined for it the most suitable regions for the cultivation in Ukraine: Autonomous Republic Crimea (correspondingly 0,2-37 and 0.6 to 3.7 t/ha), Transcarpathia (7 to 27 and 0.25-2.7 t/ha), woodland (0,2-37 and 0.6 to 3.7 t/ha), the Central forest-Steppe (5-30, and 0.2-3.4 t/ha) and warm skirts (7 to 27 and 0.25-2.7 t/ha).In accordance with the environmental assessment of the varieties of stevia honey by the method of Eberhart and Russell is recognized as intense grade Keeper, who for three years of testing it on the yield was superior to the others, he was also the most plastic. He is approached by a variety of Slavutych.The most favorable regions for cultivation of varieties of stevia was Bakhchysaray, ARC, Zhovkva, Lviv region and Chervonogvardeysk of Crimea. Gomeostaticeski characterizes the breeding value of the genotype than the figure above, the hybrid above is evaluated for suitability to contribute to the next breeding work. The coefficient of agronomic stability characterizes the economic value of the variety; it is most valuable to production there are varieties where the stability coefficient exceeds 70 %. This level correspond to all the investigated varieties.
