| 摘 要： | 研究了稍为高大韧水稻籽粒灌浆期间部分生理特性的变化，探讨了其结实率较低的生理原因。结果表明：（1）稍为高大韧水稻的株高极显著高于对照的，总粒数、千粒重显著高于对照的，但结实率极显著低于对照的，单株有效穗数和穗实粒数均与对照的差异不显著；（2）在子粒灌浆前期，稍为高大韧水稻剑叶的叶绿素含量和可溶蛋白质含量比对照的高，根系活力较强，库大源足，但后期根、叶早衰。稍为高大韧水稻的茎鞘物质表观运转率（流）极显著低于对照的，后期源不足、库源不协调、流不畅是稍为高大韧水稻结实率低的主要原因。

| Abstract: | Some physiological characteristics in grain filling period of similar higher,thicker and tougher stalk rice(SHTTSR)were studied,physiological factors related to low seed-setting rate of SHTTSR were analyzed.The result showed that:(1)compared with the controls,plant height was very significantly higher,spikelets number per panicle and weight of 1000-grains were significantly more,but seed-setting rate was very significantly lower.The difference of effective panicle and filled grains number between SHTTSR and... |
