摘要：

为了对比不同品种水稻发芽阶段的耐盐性，筛选出耐盐性更强的品种，以0、0.3%、0.5% NaCl处理水稻种子，分析不同程度盐胁迫下9个水稻品种生长指标的差异。结果表明，在水稻发芽阶段，0.3%和0.5% NaCl处理下显著抑制其出芽和生长，其中‘9311’水稻品种变化最小。与无盐处理相比，仅在0.5% NaCl处理下的芽长和根长显著降低，降幅分别为11.9%和11.5%。盐分胁迫对水稻种子发芽率的抑制程度高低顺序为‘G1’>‘银香38’>‘津原U99’>‘软香粳’>‘金稻919’>‘津原77’>‘津原E28’>‘天隆粳2号’>‘9311’。综合分析结果显示，随着盐浓度的升高，水稻的生长发育受到明显抑制，在9个水稻品种中‘9311’的耐盐性最强。

Abstract:

The aims of this study are to compare the salt tolerance of different rice varieties at the germination stage and to select varieties that have more salt tolerance. Rice seeds were treated with 0, 0.3% and 0.5% NaCl to analyze the differences in growth indices of 9 rice varieties. The results showed that the germination and growth of rice were significantly inhibited under 0.3% and 0.5% NaCl treatments at the germination stage. Among them, ‘9311’ rice variety had the least change. Compared with those of the salt-free treatment, the bud length and root length were significantly reduced only under 0.5% NaCl treatment, with a decrease rate of 11.9% and 11.5%, respectively. The inhibition degree of rice seed germination rate by salt stress was ‘G1’ > ‘Yin Xiang 38’ > ‘Jin Yuan U99’ > ‘Soft Aromatic Japonica’ > ‘Jin Dao 919’ > ‘Jin Yuan 77’ > ‘Jin Yuan E28’ > ‘Tian Long Japonica No. 2’ > ‘9311’. The comprehensive analysis showed that the growth of rice was significantly inhibited with the increase of salt concentration, and the salt tolerance of ‘9311’ was the highest among the 9 rice varieties.

Key words: rice, variety, salt stress, germination rate, salt tolerance
