The Role of Giberellins and Brassinosteroids in Reguliation of Growth and Development
Joint action of active groups of gibberellins (GA) and brassinolide (BL) on growth and development of plants Arabidopsis thaliana ecotype Landsberg erecta has been studied. It has been, that the presowing treatment of seeds the 10-9М BL reduced duration of phases of an ontogenesis of plants, accelerated growth vegetative and reproductive organs and increased seed production at plants of wild-type Ler and of mutant ga4-1. Exogenous BL in part compensated a lack endogenic GA1/4 at a mutant, enlarging the common length of shoots and restoring seed production of a mutant up to a level of wild-type. This effect might be connected with on account of augmentation of quantity of side shoots, quantities of pods, lengths of pods and quantities of seeds in pods
