| 摘 要： | 以42个水稻品种为试材,探讨农艺性状及生理特性对不同株穗型水稻品质的影响。结果表明:弯穗型、中穗型、轻穗型和高秆型垩白粒率较低,垩白度较小,外观品质较优;半直立穗型、散穗型、中穗型、中秆型糙米率、精米率和整精米率较大,加工品质较优;弯穗型、散穗型、重穗型和中秆型胶稠度较长,直链淀粉含量较低,蒸煮食味品质较优;直立穗型、散穗型、轻穗型和矮秆型蛋白质含量较多,营养品质较优。适当减小穗颈节宽度、穗长、二次枝梗数和着粒密度对改善品质有促进作用。成熟期光合速率在13.6μmol/(m2.s)时,蒸煮品质较优;叶绿素含量的积累对加工品质和蒸煮食味品质有不利影响,但能促进营养品质的改善;成熟期保持较大的叶面积指数对加工品质有促进作用,但对营养品质不利。

| Abstract: | In order to identify grain quality of rice plants with different panicle type,42 rice varieties were tested.Taking with panicle erectness,grain density,single panicle weight and plant height,the cultivars were classified into erect,semi-erect and curve panicle types;dense,semi-dense and loose panicle types;heavy,middle and light panicle types;height,middle,semi-dwarf and dwarf haulms,respectively.The effects of agronomic traits and physiological characteristics on quality were analysed.The results showed th... |
