摘要: 以籼型三系杂交稻组合汕优63以及常规籼稻扬稻6号为材料,通过稻草覆盖旱种、地膜覆盖旱种、裸地旱种和常规水种(对照)比较试验,研究了旱种对水稻灌浆期间生理活性的影响。结果表明,旱种稻叶片叶绿素含量、剑叶光合速率以及超氧化物岐化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)活性均低于水种水稻,后期尤为明显;旱种稻丙二醛(MDA)含量高于水种水稻,灌浆中后期旱种稻根系活力下降较快;上述生理指标(MDA除外)水种>覆草旱种>覆膜旱种>裸地旱种。表明与其他旱种方式相比,覆草旱种水稻的群体质量相对较好,后期生理活性较高。对覆草旱种与覆膜旱种及水种在生理活性上的差异进行了讨论。

Abstract: Two rice cultivars,Shanyou 63(An indica hybrid rice combination)and Yangdao 6(Indica),were used to investigate the physiology activity of rice grain filling cultivated with different methods.The results showed that dry-cultivation exhibited higher chlorophyll content,photosynthesis rate,and activities of superoxide dismutase(SOD),peroxidase(POD)and catalase(CAT)during grain filling,especially at the late filling stage when compared with MC.MDA content inLeaves under dry-cultivation was higher than that under MC.The root activity of dry-cultivation rice decreased rapidly at late grain filling stage.Except MDA,above physiological traits showed the order of MC>DCMS>DCMF>BC,The results suggest that grain yield was higher and rice quality better under DCMS than those under other two dry-cultivation patterns.Reasons for the differences in physiology activity of rice grain filling among DCMS,DCMF and MC were discussed in the paper.
