Abstract
Object To investigate the reason of the low germination and sprout rates by studying on inhibitory activities of the crude extracts of the seed of the dried root of Saposhnikovia divaricata (Turcz.) Schischk (DRSD) on Brassica, wheat and the seed of DRSD. Methods The ether extract and residue of the crude extract were prepared and treated by paper chromatography. The inhibitory activities of different fractions with different Rf value were determined. Effect of steeping the seed in warm water at 41 ℃ and 45 ℃ for different periods of time was also studied, respectively. Results There are intrinsic inhibitor in the seed of DRSD with strong activity. The portion of its ether extract with Rf 0.6 showed the strongest inhibitory activity for the germination of Brassica seed. The crude extract of the seed of DRSD also has the stronger inhibitory activity to the germination and growth of tender root of S. divaricata and has the same effect on aerial part of wheat sprouts. Steeping with warm water and solvent can remove most of the intrinsic inhibitor. Conclusion Intrinsic inhibitor in the seed of DRSD is the main factor that results in the low germination and sprouting slowly after seeding.
