Features of seed germination of Salvia tesquicola Klok. & Pobed in vitro

Results the data of laboratory studies of seed germination characteristics of Salvia tesquicola. Seeds was taken from collectional plants. Was found that the seeds germinated very slowly, meaning of germination was low and amounted the 22-24% for seeds from one to 6.5 years storage. With increasing of storage time to 8,5 years the meaning of germination reduced to 1%, and further seeds losed their ability to germinate. Seeds germinated in 5 days. The duration of the germination average was 6 days. Seed treatment by oxygen produced no results.

Features of seed reproduction of Fritillaria ruthenica Wikstr. in natural populations

It was found that real seed productivity of Fritillaria ruthenica Wikstr. in natural populations of the Saratov region is up to 82%. Seed germination under laboratory conditions is rather high (93–100%), however, the damaging effect of phytophagous insects has a negative impact on seed regeneration in some populations.
