| 摘 要： | 对3个产量水平不同的水稻品种叶绿素含量变化规律进行了研究。结果表明：超高产品种沈农606和高产品种辽粳294在整个生育期内叶绿素含量都高于秋光，特别是在生育后期叶绿素含量下降迟缓，成熟时明显高于秋光，但其叶绿素a/b值始终低于秋光。沈农606和辽粳294齐穗后积累的干物质较多，且产量高于秋光，可能与它们具有较高的叶绿素含量和较低的叶绿素a/b.

| Abstract: | Chlorophyll content of three rice varieties with different yield levels were studied in this experiment. The results showed that the chlorophyll content of Shennong606 and Liaojing294 was higher but the chlorophyll a/b was lower than that of Akihikari in every growing stage. The chlorophyll content of Shennong606 and Liaojing294 reduced slowly after full-heading stage and was more higher in ripening stage than that of Akihikari. Shennong606 and Liaojing294 had more dry matter accumulation and higher yield compared with Akihikari, which was caccsed by higher chlorophyll content and lower chlorophyll a/b. |
