• • • Seed productivity of Isatis costata L. in the steppe zone of Khakassia
According to their height plats were divided into three groups. Experiment tested potential and actual seed productivity, seed percentage, size and mass of 1000 fruits. Plants of all the groups significantly varied in height, number of partial inflorescences, flowers and fruits. High variation (23.8–41.0%) was observed in generative parameters for all the groups except for the number of partial inflorescences of average plants (V = 16.5%). Fruits of all the groups were uniform in size. Seed weight of one tall plant made up 12.34 g and exceeded the one of average and short plants by 3.7 and 13.1 times, respectively. Reproduction characteristics and plant height showed insignificant correlation. Average plants had medium correlation between fruit length and width. Seed percentage was high (89.1–95.0%), showing that introduction conditions corresponded to species requirements. Vegetative organs of a proper stage provided parallel growth and development of the large number of generative shoots.
