Building the inflower and realizing seed productivity of A.giganteum regel

Abstract

A. giganteum Regel are species of the subgenus Melanocrommyum. The species has a fairly high seed productivity, which varies widely. Seed productivity of two samples was studied, one of which is A. giganteum Regel (Pamir-Alai, Kugitangtau ridge, environs of Oktosh settlement); and the second, A. giganteum Regel, was obtained from the Botanical Garden of the Institute of Botany and the Academy of Sciences of the Republic of Uzbekistan. The age of the mother bulbs is 5-6 years. Under the conditions of the Tashkent region, A. giganteum Regel fruit set was 47.1 and 41.1%, the weight of 1000 seeds was 2.8 and 3.0 g, respectively (average values). The average insemination rate of A. giganteum Regel was 1.0 pcs / fetus.
