以常规施肥为对照，研究根瘤菌和胶质类芽孢杆菌不同比例配合施用对黑龙江西部干旱地区大豆开花期荧光特性、产量及品质的影响。结果表明：两种菌剂配合施用，能够提高光合能力，增加产量，其中根瘤菌和胶质类芽孢杆菌各施用150 mL?hm-2为最优处理，与对照相比，该处理叶绿素含量显著变化，Chla增加68.12%，Chlb增加87.51%，Chla/b比值降低10.32%；Fv/Fm和Fv/Fo值分别比对照提...
以鲁黄1号大豆为供试品种，在黄淮海平原地区研究了接种根瘤菌对夏大豆籽粒灌浆特性及品质的影响。结果表明：接种根瘤菌各处理的大豆产量以M5处理最高，M6处理次之，未接种根瘤菌的M1处理产量最低，三者之间达到了显著或极显著差异；蛋白质和油分的含量均以M5处理最高；籽粒终极生长量和累积籽粒重均以M5处理最大，M6处理次之，M1处理最小，且各部分间表现为中部＞下部＞分枝＞上部。相关分析表明：大豆的单株有效荚...
疫霉根腐病菌毒素对大豆不同组织中总多酚含量的影响
大豆 大豆疫霉根腐病 毒素 总多酚
2015/11/12
对大豆疫霉根腐病菌毒素胁迫下抗感不同大豆品种根、茎、叶中总多酚的含量进行了初步研究。结果表明:适宜浓度的毒素（稀释100倍，浓度为0.089 7 mg?mL-1）处理后，抗病品种根、茎和叶中总多酚在病程的大部分阶段与对照相比升高；而感病品种在整个病程中虽然在某些阶段较对照有一定的提高，但幅度不大，在病程其他阶段总多酚下降幅度远大于升高幅度。说明适宜浓度的大豆疫霉菌毒素可以起到激发子作用。
