以吉林省8个具有代表性的新老粳稻品种为供试材料,对其单株质量、叶片质量、茎鞘质量和穗质量进行测量,分析不同生育时期单株各器官干物质的积累与产量的关系。研究结果表明:新老水稻品种的单株质量、叶片质量和茎鞘质量这3个指标的变化规律不同,在整个生育期内,叶片质量与产量一直保持显著正相关,在分蘖期和乳熟期达到极显著正相关。茎鞘质量与产量相关性波动较大,在拔节期茎鞘质量与产量达显著负相关,在抽穗期达极显著正相关,剩余生育期内则表现为显著正相关,穗质量与产量的相关性在整个生育期内几乎都为极显著正相关,是产量增加的反应。
Eight representative old and new Japonica rice varieties in Jilin Province were used as materials to measure the plant quality, leaf quality, stem and sheath quality and ear quality. The accumulation and yield of dry matter in different organs at different growth stages Relationship. The results showed that the three indicators of plant quality, leaf quality and stem-sheath quality of old and new rice varieties varied regularly. During the whole growth period, the leaf quality and yield had a significant positive correlation. At the tillering stage and milk ripening Period reached a significant significant positive correlation. There was a significant positive correlation between the quality of stem and sheath and the yield. There was a significant negative correlation between the quality of stems and yield at jointing stage, the significant positive correlation at heading stage and the significant correlation between the quality of stem and the yield Almost all of the sexually significant positive correlations throughout the growing season were the result of increased production.
