Abstract
Maize seeds were soaked in the solution of extracts of Datura stramonium L's alkaloids to study the effects on maize seeds germination and seedling growth.The results showed that 0.1 mg/ml alkaloids extract promted the seeds germination and inhabited seedling growth.Above 0.2mg/ml extract of Alka- loids was unfavourable to seed germination and seeding growth of maize,at the stage of the seeds germina- tion,activity ofα-amylase,the seeds germination rate,germination index and vigor index were all de- creased,with the concentration incersed.It was also found that Datura Stramonium L's Alkaloids had in- habited to the seedling growth of maize,α-amylase activity,igor of roots system,seedling height,and the contents of cholorophyll and protein were suppressed apparently.The activity of peroxidase(POD)was re- duced continuously with the concentration increased,the activity of superoxide disnutase(SOD)and cata- lase(CAT)were dropped at lower concentration,increased at higher concentration.
