- 摘要:
- 以耐盐性不同的2个葡萄品种“夏黑”（耐盐性较弱）和“里扎马特”（耐盐性较强）为试材,研究了在0、2、4 g/kg 3个盐胁迫水平下对2个葡萄品种叶面喷施0、75、150 mg/L浓度的5-氨基乙酰丙酸（ALA），对2个品种叶片中的可溶性蛋白质含量、脯氨酸含量、丙二醛(MDA)含量、相对电导率以及抗氧化酶(CAT、POD、SOD)活性的影响。结果表明：利用2 g/kg盐胁迫和75 mg/L ALA，4 g/kg盐胁迫和150 mg/L ALA分别对“夏黑”和“里扎马特”葡萄进行处理时，二者叶片中的可溶性蛋白质含量、脯氨酸含量以及超氧化物歧化酶（SOD）、过氧化物酶（POD）、过氧化氢酶（CAT）活性均显著增加，而相对电导率与丙二醛（MDA）含量则显著降低。
- Abstract:
- Using two salinity-resistance grape variants:‘Summer black’(weak salt resistance) and ‘Rizamat’(strong salt resistance) as the materials,the soluble protein content,the proline content,MDA content,the relative electric conductivity and the level of three enzymes’activity(CAT,POD,SOD) after treating the leaf surface with ALA at the concentration of 0,75,150 mg/L,which respectively corresponds to three salinity-stress levels of 0,2,4 g/kg were studied.The results showed that as for the ‘Summer black’(75 mg/L ALA,2 g/kg salinity stress) and the ‘Rizamat’(150 mg/L ALA,4 g/kg salinity stress) respectively,the soluble protein,proline content and the level of the three different enzymes’activity increased significantly,however the MDA content,relative electric conductivity decreased significantly.
