摘要/Abstract

摘要： 利用相同遗传背景不同株形水稻浙辐802等基因系为材料,研究了IG1、IG4、IG25和IG26与无芒稗的竞争和化感作用潜力,探索了二者之间的相互关系.结果表明,IG1和IG4的植株高度和分蘖角度显著大于IG25和IG26,但它们的根系活力却显著小于IG25和IG26.IG1和IG4对无芒稗生物量干重抑制率分别达到15%和17%,显著高于IG26的64%,表明水稻与无芒稗竞争力与水稻植株高度和分蘖角度成正比,而与水稻根系活力成反比.IG1叶片水浸提液对无芒稗根长抑制率为77.6%,显著高于非化感对照品种秀水63,而植株形态相近的IG4的化感作用却未达到显著水平,显示在相同遗传背景下水稻化感作用强弱与水稻株型无相关性.

Abstract: Zhefu 802 rice isogenic lines IG1,IG4,IG25 and IG26 have the same genetic background but different plant morphology.This paper studied their competition and allelopathy against barnyardgrass.The results showed that IG1 and IG4 had higher plant height,bigger tiller angle and less root vitality than IG25 and IG26,and provided 15% and 17% control of barnyardgrass plant dry weight,which were significantly higher than IG26.The competition ability of test rice isogenic lines against the weed was positively correlated with their plant height and tiller angle,but negatively correlated with their root vitality.The inhibition rate of the water extract of IG1 leaves on barnyardgrass root length was 77.6%,significantly higher than that of non-allelopathic material Xiushui 63,while the IG4 which has the similar plant morphology with IG1 didn't show any significant allelopathy.It seems that there were no correlations between allelopathy and morphological characters of rice under the same genetic background.
