【摘要】 测定了10%PEG-6000胁迫后香蕉幼苗叶片的可溶性糖、可溶性蛋白、脯氨酸、丙二醛、质膜透性、超氧化物歧化酶活性和香蕉根系活力的变化情况。结果显示,胁迫后3 d,可溶性糖、脯氨酸、丙二醛、根系活力比对照分别提高48.74%、100.55%、58.36%和84.50%,可作为下一步香蕉抗旱调节物质的筛选指标。更多还原

【Abstract】 Brazil banana seedlings were cultured under 10% PEG-6000 water conditions to observe their changes of leaf soluble sugar,soluble protein,proline,MDA,membrane permeability,SOD and root activity.It was found that water stress improved soluble sugar,praline,MDA and root activity by 48.74%,100.55%,58.36% and 84.50%.These physiological indexes could be used to select banana drought resistance regulating materials.更多还原
