摘要: 以水稻‘协优赣2号’种子为材料,探讨不同浓度铬对其萌发的影响。结果表明:低浓度Cr6+(≤10 mg/L)对该水稻种子萌发没有抑制作用;当Cr6+浓度≥50 mg/L时对其萌发有显著抑制作用。Cr6+对该水稻种子的发芽率影响很小,但一定程度上延迟了发芽;Cr6+对胚根生长抑制作用最大。

关键词: Cr6+, 水稻种子, 萌发, 影响

Abstract: This paper studied the different concentrations of Cr6+ on germination of rice (‘Xieyougan 2’) seeds. The results showed that: the low concentration of chromium (≤10 mg/L) did not inhibited germination of rice seed; when the chromium concentration > 10 mg/L, the rice seed germination was inhibited. Influence of Cr6+ on rice seed germination rate was very small, but delayed germination time to some extent, the maximum inhibitory effect was the radicle growth.

Key words: Cr6+, rice seed, germination, influence
