谷子水浸液对谷莠子种子萌发及幼苗生长的化感作用OACSTPCD
Allelopathic Effects of Water Extracts from Millet on Seed Germination and Seedling Growth of Giant Foxtail
为探究谷子与谷莠子生长之间的化感作用,本试验以'金选6号'谷子水浸液、'大狗尾草'为试验材料,研究了不同浓度水浸液对谷莠子种子萌发及幼苗生长的影响.结果表明:不同浓度水浸液对其种子萌发及幼苗生长表现为"低促高抑".原液处理下种子发芽率较对照降低13.888%,化感效应指数为-0.139.原液、10倍稀释液处理下根芽长及鲜干重等综合效应指数分别为-0.070、-0.034,表现出化感抑制作用,且植株全长、叶面积、叶绿素含量、SOD均低于对照.50、…查看全部>>
In order to explore the allelopathy between millet and giant foxtail growth,the effects of different concentrations of water extracts on foxtail millet seed germination and seedling growth were studied by using'Jinxuan 6'and'Setaria viridis'as experimental materials.The results showed that different concentrations of water extracts have'low promotion and high inhibition'on seed germination and seedling growth.Compared with the control,the emergence rate was …查看全部>>
