THE INFLUENCE OF SUBSTITUTED 1,3,4,5-TETRAHYDRO-2H-1,5-BENZODIAZEPIN-2-ONE DERIVATIVES ON NARROW-LEAVED LUPIN (LUPINUS ANGUSTIFOLIUS L.) GROWTH IN VITRO

Abstract

In this study, we have examined synthesized 1,3,4,5-tetrahydro-2 H -1,5-benzodiazepin-2-one derivatives and their influence on the growth in vitro of narrow-leaved lupin ( Lupinus angustifolius L.). Laboratory testing implied germination of VB Derliai and VB Vilniai seeds in Petri dishes. The greatest impact on VB Derliai lupin root growth (3.11 ± 0.48 cm) was shown by 4-methyl-1,3,4,5-tetrahydro-2 H -1,5-benzodiazepin-2-one, the longest stem (1.58 ± 0.39 cm) and the maximum lupin biomass (0.473 ± 0.058 g) were obtained by using 5-acetyl-3-methyl-1-(2-oxo-2-phenylethyl)-1,3,4,5-tetrahydro-2 H -1,5-benzodiazepin-2-one. With VB Vilniai seeds, most root growth-promoting (1.88 ± 0.54 cm) was the 1,3,4,5-tetrahydrate-2 H -1,5-benzodiazepin-2-one compound, the longest stem (1.07 ± 0.09 cm) was achieved by using 5-acetyl-3-methyl-1-(2-oxo-2-phenylethyl)-1,3,4,5-tetrahydro-2 H -1,5-benzodiazepin-2-one, and the maximum lupin biomass (0.526 ± 0.031 g) from using 4-methyl-1,3,4,5-tetrahydro-2 H -1,5-benzodiazepin-2-one.
