Description
The effect of seeds shapes and sizes to field survival, plant stand, harvesting amount and structure of calendula crude drug were under investigation. Biological feature of calendula is heterogeneous seeds formation, when the same inflorescence forms seeds of various shapes and sizes. The following seeds fractions according to their shapes and sizes were used for sowing: uncinate shaped, crescent shaped as well as unseparated, including, except uncinate and crescent seeds, ring-form and scaphoid shaped seeds. It was discovered that maximum indices of laboratory, field survival of calendula seeds and plant stand were in conjunction with uncinate shaped seeds. Maximum crude drug harvest was in conjunction with the sowing seeds of uncinate shape, varied from years from 2.11 to 2.40 t/h; minimum- at unseparated seeds sowing, varied from years from 1.83 to 2.05 t/h. Crude drug extreme efficiency was determined in 1-3 gatherings by inflorescence weight gain and its quantity increase on the same plant. According to the size of elements of crude drug harvesting structure (inflorescence quantity and mass of the same plant, the same inflorescence mass) the variant of uncinate shaped seeds sowing had advantages
