To the study of fruit bearing pecularities of Iris x hybrida hort. under the conditions of the Southern Coast of the Crimea

Abstract

The article describes approaches to the study of fruiting cultivars Iris x hybrida hort. of the collection of the Nikitsky Botanical Gardens National Scientific Center of the garden group of high species, on the example of the cultivar 'Sky Hooks', and presents the primary processing of experimental data. The ratio of the average values of potential and actual seed productivity depends on: the number of generative shoots on the plant; the number of "levels" or branches on the generative shoot; the number of flowers and the number of fruits on the generative shoot; the number of fruits at a certain "level" of their location. Actual seed production of cultivars 'Sky Hooks' two times less potential, regardless of the number of generative shoots per plant, "level" location of the fetus, the number of "levels" on generative shoots, number of flowers and fruits on one generative shoots. The highest average values of potential and actual seed productivity correspond to the 3rd and 4th "levels".
