辽宁省水稻品质兼及品质与产量关系的研究rnⅣ.不同源库关系与稻米品质

摘要

通过2年7个品种源库关系调节试验，研究了稻米品质生理。结果表明，人工减库会提高糙米率、精米率、AC、GC，垩白粒率与垩白面积变化复杂，而减源对米质的影响恰好相反。处理间变异大小与年份及品种本身固有的源库矛盾有关%The rice quality physiology was studied on the experiments of regulating nutritional source and sink through seven varieties and two years. These results showed that artificially decreased sink would be able to increase the percentage of brown rice and polished rice, the content of AC and GC, the percentage and the size of chalkiness changed complicatedly. The effect of decreased nutritional source on grain quality would be on the contrary
