Abstract:
With the aged pumpkin seed as experimental materials,treatments including different concentration,priming time,and priming temperature of three initiators (CaCl2,GA3,PEG 6000) were set,with H2O as control,the effect of different priming methods on seed germination and physiological characteristics of aged pumpkin seedlings were investigated.The results showed that,compared with the CK,1.0% CaCl2 primed 8 hours under low temperature at 8 ℃ was the optimal method for the priming of aged pumpkin seeds,the germination energy,germination rate,germination index,and vigor index were enhanced by 20%,22%,18% and 66% respectively.Moreover,the activities of SOD and CAT in aged pumpkin seedling leaves were enhanced,while the MDA contents were decreased significantly,and the plant growth well improved.The results suggested that the aged pumpkin seed germination could be promoted and the effects of seed aging and decay on physiological status of seedlings could be alleviated by enhancing the antioxidant capacity of seedlings.
