The article presents the results of studies of growth stimulators – succinic acid (1 g/l), heteroauxin (0,2 g/l), reastim (1 g/l) and epine (1 ml/l) on morphometric parameters of bean sprouts and seed quality.

Pre-sowing seed treatment by growth stimulors increased seed yields (similarities and germination energy). The analysis has shown that the most effective was application of reastim and succinic acid.

It was established that growth stimulators significantly changed the morphogenensis of bean seeds. It was found that the hypocotyl length of  beans sprouts under heteroauxin (0,2 g/l) and reastim (1 g/l) treatements decreased by 64 % and 65 % concordanly, compared with control, whereas the application of epine (1 ml/l) increase the hypocotyl length by 41%. Succinic acid (1 g/l) practically did not affect on the hypocotyls length of bean sprouds.

The results indicate that epine (1 ml/l) pre-sowing seed treatment led to an increase in root length of bean sprouds by 26,6 % during the germination while all other compounds reduced this parameter.
