Seed Productivity and Biological Features of the Seeds of Some Species of Asteraceae Family During Introduction
I. Ya. SARLAEVA, E. V. BAIKOVA
Abstract
The features of bearing were considered for 14 species of annual decorative plants of Asteraceae family introduced in the forest-steppe region of West Siberia and belonging to different ecological-biological groups. Laboratory germination and germinating capacity of seeds were investigated for different storage time; the dynamics of germination was also studied. The potential and actual seed productivity of inflorescences on the sprouts of different embranchment orders were determined for four model species (Dimorphotheca pluvialis, Brachycome iberidifolia, Sanvitalia procumbens, Tagetes patula). The productivity coefficients were calculated for each species per one plant and per a sprout of the corresponding order.
