| 摘 要： | 应用三十烷醇(TA)处理水稻，结果表明：TA能促进水稻种子萌发，提高发芽率和发芽势，提高叶片叶绿素含量和促进光合速率。不同时期、不同质量浓度的TA对水稻叶绿素含量的影响不同，以幼穗分化初期喷施0．5mg／LTA 0．2％KH2PO4的效果最明显，差异达到显著水平。在水稻幼穗分化初期、孕穗期和灌浆期喷施TA均能提高光舍速率，且以1mg／LTA和0．2％KH2PO4混和喷施效果最佳，该结果为水稻生产上喷施TA质量浓度和时期提供了科学依据。 |

| Abstract: | Rice treated with triacontanol (TA) , the results showed that TA increased the percentage of seeds , germination energy, chlorophyll content and photosynthesis rate .During different developmental stages ,various concentration of TA caused different results to chlorophyll content . And it has a dramatic effect on rice which sprayed by 0.5 mg/L TA and 0.2% KH_2PO_4 during the differentiation of juvenile ear stage. TA also enhanced the photosynthesis rate during the differentiation of juvenile ear, incubation and maturation stage. Likewise , it has a dramatic effect on rice given by 1 mg/L TA and 0.2% KH_2PO_4 . These results provide scientific basis for mastering the spray time and concentration of TA properly in rice production. |
