Особенности накопления пластидных пигментов растениями озимого тритикале

Abstract

The article presents the results of studies on the content and accumulation of plastid pigments in various plant organs of winter triticale variety Ingen 35 grown after various predecessors in 2014. It is found that after next predecessors grain peas and oats + vetch in booting phase chlorophyll "a" and "b" in the leaves is much higher than in the later phases - earing 16,245 mg / g. of abs. dry matter and 10,387 - in pea for grain and 13,258 mg / g. of abs. dry matter and 9,104 mg / g. of abs. dry matter after vetch + oats. Plant organs of winter triticale accumulate different amounts of chlorophyll - the leaves 48.2 - 51.8%, stems - 36.6 - 39.8% and ears - 11.6 - 12.0% from the amount accumulated in the whole plant. Higher accumulation of chlorophyll in plants of winter triticale grown after peas contributed to the formation and greater grain yield by 942 kg / ha, compared to the predecessor vetch + oats.
