Биологические особенности семян видов рода Amaranthus L. при интродукции в Ботаническом саду Уральского федерального университета

Abstract

In the botanic garden of Ural Federal University introduction of different species of Amaranthus L. is carried out for thirty years. We studied the sowing qualities of seeds belonging to 11 amaranth samples. The study showed that amaranth seeds are homogeneous. Germinative energy and germinating capacity of amaranth seeds remain at a high level up to 8–9 years of storage. The lightest seeds of A. powellii subsp. bouchonii and A. retroflexus lost laboratory germinating capacity after six years of storage. Seeds of other amaranth species lost germination after 12–13 years of storage.
