Abstract:
Mini-watermelon variety of ‘Meiyue’ was used as test material,adding different concentrations of methyl jasmonate,calcium chloride and proline in NaCl solution,soaking seeds of ‘Meiyue’ watermelon,effects of exogenous substances on seed germination of watermelon were studied.The results indicated that the concentration of 130 mmol?L-1 NaCl was the best treatment concentration,could be used as the treatment concentration of watermelon seed germination;methyl jasmonate,calcium chloride and proline could increase the germination rate,germination potential,germination index,vigor index and root activity,root length and embryo length of seed under salt stress.Among them,the best effects were obtained by adding proline,the optimum concentration of proline was 0.2 mmol?L-1.At this concentration,the germination rate and germination potential were significantly improved.The results showed that three kinds of exogenous substances could alleviate the damage of watermelon seeds and promote the germination of watermelon seeds.This study provided the basis for the application of three exogenous substances in watermelon cultivation.
