Effect of NaCl Stress on Seed Germination of Watermelon
The effect of watermelon seed germination under NaCl stress was stuied. The results showed that as NaCl stress concentration rose, the inhibitive effect on the seed germination was obviously increased. When NaCl stress concentration was at 25 mmol/L, the weight of fresh bud and the weight of dried bud were a little higher than those of CK and when NaCl stress concentration was 25～50 mmol/L, the germination percentage was a little higher compared with CK, but for others. The germination percentage and bud and root length, weight of fresh root and bud, weight of dried root and bud, were decreased with the increase of NaCl stress concentration. Linear correlations were found between the inhibition rate of germination percentage, bud and root length, weight of fresh root and bud, weight of dried root and bud and the NaCl stress concentration.
