this study was conducted to investigate allelopathic effect of the essential oil of artemisia herba-alba asso., on seed germination characteristics of  agropyron desertorum and agropyron cristatum in a laboratory experiment. essential oil was extracted from the aerial parts of artemisia herba-alba using a clevenger-type apparatus. the volatile chemical compositions of artemesia herba-alba were ...

Drying of seeds of Agropyron desertorum (Fisch. ex Link) Schult. did not result in breakdown of alpha-amylase nor impair the ability of seeds to resume its synthesis when moistened again. beta-Amylase activity did not change during 5 days of germination at a water potential of 0 atmosphere nor during 40 days of incubation at -40 atmospheres. Seeds synthesized alpha-amylase at 0, -20, and -40 at...
