- 摘要:
- 以5个草莓品种为试材,通过盆栽试验,比较和分析了不同草莓品种苗期在不同干旱胁迫下的9个生理指标变化趋势,并采用主成分分析、隶属函数及聚类分析进行抗旱性综合评价,以揭示草莓对干旱环境的适应能力,筛选草莓抗旱性相关指标和抗旱资源。结果表明:干旱胁迫下5种草莓的相对含水量呈下降趋势,相对电导率、MDA含量、抗氧化酶活性(超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT))和3种渗透调节物质(脯氨酸、可溶性蛋白质、可溶性糖)含量均呈上升趋势,但不同的品种其变化幅度差异较大;抗旱性综合评价结果表明,‘甜查理’‘晶玉’为抗旱性较强品种,‘晶瑶’为抗旱性中等品种,‘宁丰’‘艳丽’为抗旱性较弱品种。
- Abstract:
- In order to explore the responses of strawberry to drought stress and screen the index of drought resistant and tolerance resources,nine physiological and biochemical indexes of five strawberry cultivars were compared and analyzed in seedling stage under different levels of drought treatments.Then the drought tolerances of five strawberry cultivars were evaluated based on principal components analysis,subordinate function and cluster analysis.The results indicated that the relative water contents were showing decreasing trend,electrolyte leakages,MDA contents and activity of antioxidant enzymes (superoxide dismutase (SOD),peroxidase isozyme (POD),catalase(CAT)) and three kinds of osmoregulation substances (proline,soluble protein,soluble sugar) contents increased.But there were large differences of variations in nine physiological indexes of different cultivars.In this study,the drought tolerance of five strawberry cultivars were stronger(‘Sweet Charlie’ and ‘Jingyu’),medium (‘Jingyao’) and weaker (‘Ningfeng’ and ‘Yanli’),respectively.
