| 摘 要： | 本文研究了用不同浓度的Ce( NO3)3、La( NO3)3、KNO3、KH2PO4、青霉素、IAA、NAA浸种对水稻种子Q优6号发芽的影响,结果表明除NAA外,其他几种外源物质对提高种子的发芽率均有一定的效果.经IAA、KNO3浸种处理能极显著提高种子的发芽率,经Ce( NO3)3、KH2 PO4浸种处理能显著提高种子的发芽率,经La(NO3)3、青霉素浸种处理对种子的发芽率提高不显著,而经NAA浸种处理对种子的发芽有一定的副作用. |

| Abstract: | In this paper,the effects of seed soaking treatment with different concentrations of Ce(NO3)3,La(NO3)3,KNO3,KH2PO4,penicillin,IAA and NAA on seed germination percentage of rice variety Q you 6 were investigated.The results showed that it had some effect on improving seed germination percentage with all exogenous substances except for NAA.The seed germination percentage was significantly increased with IAA and KNO3,and with Ce(NO3)3 and KH2PO4,and was not significantly increased with La(NO3)3 and penicillin,... |
