Abstract:
P.obconica seeds were used as material to explore the effect of different concentrations of CaCl2,SA and GB on seeds germination under drought stress of 9% PEG-6000.The results showed that,seed germination of P.obconica,under drought stress of 9% PEG-6000 (CK2),was significantly lower than that of the blank control group (CK1);treatments of a certain concentration of CaCl2,SA and GB could promote seeds germination of P.obconica,and the best concentrations were 15 mmol?L-1,10 mg?L-1,5.0 mmol?L-1;the promoting effect of CaCl2 on seeds germination was the best and SA was the worst,between three exogenous substances.
