摘要
以‘津优1号’和‘春四’黄瓜为试验材料,研究了不同程度水分胁迫对黄瓜幼苗生理生化指标的影响,以期为黄瓜的抗旱机制研究和抗旱栽培提供理论依据。结果显示,随着水分胁迫程度的增大,2个黄瓜品种幼苗的叶绿素a、叶绿素b和叶绿素a+b含量逐渐下降;相对电导率、丙二醛含量、可溶性糖含量、脯氨酸含量以及SOD活性都随着水分胁迫程度的增大呈明显上升趋势。隶属函数法评定这2个黄瓜品种的耐旱性顺序为‘津优1号’>‘春四’。
Jinyou No.1 and Chun No.4 cucumber cultivars were used as materials to study the effects of different water stress on physiological indexes of cucumber seedlings,and to provide theoretical basis for research on drought-resistance mechanism and cultivation of cucumber.The results showed that with the increase of water stress,the content of chlorophyll a,the content of chlorophyll b and the content of chlorophyll a+b decreased,while the relative conductivity,MDA content,soluble sugar content,proline conte...
