MORPHOLOGICAL FEATURES AND SOWING QUALITIES OF SILYBUM MARIANUM (L.) GAERTN. VARIETY
Description
Distinctive features of seeds of Silybum marianum two varieties – the ‘Start’ and the ‘Debut’ on morphology are presented in the article and also data on influence of storage conditions on sowing qualities of seeds are submitted. Seeds of two varieties differ among themselves on coloring, a form and mass of 1000 seeds. The ‘Debut’ is characteristic sign of a variety existence of dark strips on a surface of seeds. Results of two years of tests have shown that during 1 year from the moment of collecting seeds energy of germination and viability gradually increases and reaches the maximum values in 12 months independently of storage conditions. The viability of seeds of the Silybum stored at the room temperature within 18 months decreases by 8,5-12,5%. As a result of an experiment it has been established that in the conditions of not heated room successful storage of seeds is possible not longer than one year, after that sowing qualities of seeds sharply decrease
