| In order to improve the seed germination ability and cultivate strong seedlings of small gourd, the seed of Wax gourd were treated by different concentrations of KNO3, CaCl2, GA3, 6-BA and several combination of medicaments. The results showed that all the treatments can promote seed germination, and improve germination energy and germination percentage. Compared to the control, treatment with KNO3 4 g/L , CaCl2 1 g/L , GA3 300 mg/L, 6-BA 100 mg/L and 6-BA 50 mg/L + KNO3 500 mg/L improve the germination energy by 54.66%, 37.34%, 40.00%, 48.00% and 48.00%, and improve the germination percentage by 21.69%, 13.20%, 20.74%, 16.98% and 26.40%, respectively. Taken strong seedling factors into consideration, including leaf area, hypocotyls length and root length, the treatment of 6-BA 50 mg/L+KNO3 500 mg/L presented the best results, followed by KNO3 4 g/L treatment. |
