Особливості використання резервних сполук кінських бобів за умов ското- та фотоморфогенезу

Abstract

Principal changes in source-sink system performance of Vicia faba L. during germination periods under light and darkness influence were studied. The linear sizes of organs and total seedling increased under darkness influence. The indicators of organs’ dry matter were increased and, accordingly, dry matter mass of cotyledons in scotomorphic plants was decreased. Nutritive substances were diverted vigorously under dark conditions. Higher utilization rates for needs of organs formation during germination evidenced by that fact. Germination processes were connected with intensive outflow of resources for Vicia faba organogenesis. The changes indicated intensive protein hydrolysis in dark that started after the starch breakdown. There is no specific impact of mineral matters' outflow for vegetative growth in comparison to dry seeds, which suppose due supply with mineral matters in both experimental variants.
