| 摘 要： | 将黑豆幼苗用甘露醇处理后,观察其形态特性与生长状况;用过氧化氢、氯化钠分别浸泡黑豆种子,测定幼苗叶片脯氨酸含量,研究不同处理对黑豆抗旱性的影响。结果表明:甘露醇处理造成黑豆幼苗水分胁迫,致使植株较低,株型紧凑,叶直立,叶面积小,叶片薄,叶色淡绿,根毛较长,根系发达并导致叶片水势降低,幼苗的抗旱能力增强;过氧化氢处理使幼苗叶片脯氨酸含量明显下降,幼苗的抗旱性减弱;而氯化钠处理造成幼苗叶片脯氨酸含量显著提高,抗旱性增强。

| Abstract: | The black soybean seedlings were sprayed with mannitol,subsequently,their morphological characteristics,growth status were observed;and the soybean seeds were soaked with different concentration of hydogen peroxide(H2O2) and sodium chloride(NaCl) respectively,then the seedling proline content was determined,to study the effect of different treatments on drought resistance of black soybeans.Results indicated that the black soybean seedlings treated by mannitol resulted in lower plant,compacted plant-type,sma... |
