血叶兰幼苗对干旱胁迫的生理响应及其抗旱性指标筛选OA
Physiological Response of Ludisia discolor Seedlings to Drought Stress and Screening of Drought Resistance Indicators
为探究血叶兰Ludisia discolor对干旱胁迫的耐受性,以炼苗后自然生长约6 个月龄的血叶兰组培苗为试材,盆栽控水模拟干旱条件下,分析幼苗生长、生理生化指标及生物活性成分的变化,并通过相关性及主成分分析评价其抗旱性主要响应因子,为血叶兰保育栽培的水分管理提供参考.结果表明,随着干旱程度增加,血叶兰株高较对照组呈下降趋势,但茎粗无明显影响;叶片相对含水量减少,叶绿体色素(Chl)含量先上升后降低,而花色素苷(ACN)含量则呈上升趋势.干旱胁…查看全部>>
In order to investigate the tolerance of Ludisia discolor to drought stress,the experiments potted water control to simulate drought were used to study the changes of growth,physiological and biochemical indicators,and bioactive components in L.discolor seedlings with around 6 months of age under different water treatments.The main response factors to drought resistance were evaluated through correlation analysis(CA)and principal component analysis(PA),which…查看全部>>
