Study on nodulation and nitrogen fixation of azospirillum brasilense induced by 2 , 4 - d in the roots of maize 誘導(dǎo)固氮螺菌在玉米根部結(jié)瘤及固氮效果的研究
Growth and nodulation competitiveness of poly - 3 - hydroxybutyrate metabolism mutants of sinorhizobium meliloti and the effects of exogenous biotin 苜蓿根瘤菌聚羥丁酸代謝突變體的競爭生長和結(jié)瘤能力以及外源生物素的影響
Field germination , nodulation status and growth parameters were varied significantly in the soil amended with sludges in comparison to control 與對(duì)照幼苗相比,混合污泥的土壤中生長的幼苗田間發(fā)芽、分枝狀況及其他生長參數(shù)均發(fā)生了顯著變化。
We conclude that the gene we studied is a new loci required for efficient nitrogen fixation and for competitive nodulation of soybeans by bradyrhizobium japonicum strain gx201 我們認(rèn)為在突變體菌株gx217中tn5gusa5所插入的開放閱讀框架是一個(gè)新的與競爭結(jié)瘤有關(guān)的基因。
Eleven wood legume plants were selected and their morphologic and anatomical characteristics were compared in order to analysis the relationship between the root structure and their nodulation 摘要選取了11種豆科木本植物,比較了它們的根部外部形態(tài)和解剖結(jié)構(gòu)特點(diǎn),分析這些特點(diǎn)與結(jié)瘤的關(guān)系。
