The structure of the inflorescence and the implementation of seed productivity of Allium cristophii Trautv. in Moscow region

A. cristophii Trautv. [ A. albopilosum C.H. Wright, A. bodeanum Regel, A. walteri Regel] is a type of subsection Cristophiana . It is an extremely polymorphic taxon. The species has a fairly high seed productivity, which varies widely. The seed productivity of two samples was studied, one of which, under the name A. albopilosum S. N. Wright, was introduced from the Netherlands, and the second A. cristophii was obtained from the Botanical Garden of the Institute of Biology of the Komi Scientific Center, Ural Branch of the Russian Academy of Sciences. The age of the mother bulbs - 6-7 years. In Moscow Region A. albopilosum and A. cristophii fruit sticking was 89.2 and 88.5%, the real seed productivity was 4.54 and 2.72 g per inflorescence, the weight of 1000 seeds was 5.69 and 5.20 g, respectively (average values). In A. albopilosum , an average insemination was found - 5.54 units / fruit, with up to 13 seeds per fruit being noted in the lower tier, 15 in average, and 11 seeds per fruit in the upper tier. A. cristophii recorded an average insemination of 4.93 pieces / fruit, while in the lower tier there was a formation of up to 11 seeds per fruit, average - 10, top - 8 seeds per fruit.
