为探究不同浓度的外源赤霉素添加对苜蓿(Medicago sativa)-根瘤菌共生体系结瘤过程的影响及其作用机制,本试验在室内控制条件下,外源施加不同浓度的赤霉素,观察其对苜蓿根瘤数、干鲜重、根茎长、苜蓿-根瘤菌共生结瘤过程中根瘤原基、根... 为探究不同浓度的外源赤霉素添加对苜蓿(Medicago sativa)-根瘤菌共生体系结瘤过程的影响及其作用机制,本试验在室内控制条件下,外源施加不同浓度的赤霉素,观察其对苜蓿根瘤数、干鲜重、根茎长、苜蓿-根瘤菌共生结瘤过程中根瘤原基、根毛卷曲、类黄酮物质分泌的影响。结果显示:10^(-9)mol·L^(-1)的赤霉素可以促进nod基因的表达,引起植株根系黄酮类物质的分泌量增加,诱导形成更多且活性更强的根瘤原基,促进根瘤的形成。10^(-5)mol·L^(-1)赤霉素抑制根毛卷曲过程,从而减少根瘤数。因此,在紫花苜蓿结瘤过程中可适当添加外源赤霉素以提高结瘤效果,促进作物生长。 展开更多

The aim of this study is to assess the occurrence and type of violence suffered by women with breast cancer in the High Complexity Care Unit of a municipality in the South of Minas and patients in a support group of the University of the South of Minas Gerais. For that aim, a descriptive-exploratory methodology was applied through the quantitative method. Data were collected through a semi-structured form applied in individual interviews over a period of three months. We interviewed 57 patients and among those, 20 women (35.08%) reported having experienced some form of violence at some stage of their life, and the most frequently mentioned was the psychological violence followed by physical aggression. Although it was possible to identify that violence against affected these women, complaints against the aggressor were not affected. 展开更多
