毕节特色烤烟品种抗旱性评价
采用盆栽试验,研究了4个烤烟品种在干旱胁迫条件下的主要农艺性状、生物量积累、叶片保水力、相对含水量、根系丙二醛、脯氨酸含量等生理指标,并通过隶属函数法对各品种的抗旱性进行综合分析,以期明确烤烟品种间抗旱性的差异.结果表明：在干旱胁迫条件下,4个烤烟品种的主要农艺性状、干鲜重积累量及叶片相对含水量均显著下降,云烟87下降幅度最小,毕纳1号次之,黔西1号下降幅度最大;叶片保水力表现为云烟87＞毕纳1号＞黔西1号＞韭菜坪2号;各烤烟品种根系丙二醛含量和脯氨酸含量均显著增加,云烟87和毕纳1号丙二醛含量增加量较少,脯氨酸含量增加量较大,韭菜坪2号和黔西1号则相反;隶属函数法综合分析发现抗旱性由强到弱顺...

| Notes | 51-1213/S Flue-cured tobacco; Variety; Drought resistance; Subordinate function Drought resistances of 4 different flue-cured tobacco cultivars wee studied under drought stress conditions in pot experiments.Some indexes,including the main agronomic botanical characters,accumulation of the plant,leaf relative water content,water-holding capacity,MDA content and proline content,were screened out,and the drought resistance of each type was comprehensively analyzel by membership function to clear the differences of drought resistance of flue-cured tobacco varieties.The results showed that under drought stress,their main agronomic botanical characters,both plant fresh and dry mass and leaf relative water content were decreased obviously,but the deceasing range of ‘ Yunyan 87＇ was the most less,‘ Bina 1＇ was relatively less,and ‘ Qianxi 1＇ was the largest.Leaf water holding strength was in order of ‘ Yunyan 87＇ ＞ ‘ Bina 1＇ ＞ ‘ Qianxi 1＇ ＞ ‘ Jiucaiping 2＇.The content of MDA and proline in flue-cured tobacco roots incr |
