摘要:
对5个柳树树种的叶组织蒸腾强度、离体叶片水分散失速度、叶组织含水率、水分损失率进行了测定结果表明,苏柳在正常生长情况下较青刚柳和准噶尔柳节约水资源;由水分散失速度得出这5个树种在极端干旱条件下的抗性顺序为J194柳>J172柳>J369柳>青刚柳>准噶尔柳;苏柳叶组织对其含水量变化反应敏感,出现水分胁迫后,组织含水率呈缓慢下降趋势,在组织含水率下降至50%时,仍具活叶特征,表明苏柳叶组织具有很强的生命力和抗干旱能力;J194柳的叶组织抗逆性最强,其次为J172柳和J369柳,青刚柳和准噶尔柳的叶组织抗逆性最弱。西北林学院学报21卷第5期杨 斌等柳树叶组织蒸腾强度及离体叶片水分自然散失速度测定分析
Abstract:
Leaf tissue transpiration intensity, leaf moisture dissipation speed, the humidity ratio of leaf tissue and wet loss rate of Salix jiangsuensis had been studied,the results showed that S.jiangsuensis expend water lesser than S. viminalis and S. sonjarica,so it fit the area of water deficiency. On drought conditions, five varieties arrange in drought resistance was below, S.jiangsuensis'194'>S.jiangsuensis'172'>S.jiangsuensis'369'>S.viminalis>S.sonjarica. The leaf tissue of three strains of S.jiangsuensis was sensible to the water content,the leaf tissue humidity ratio dropped slowly in condition of water intimidation,the leaf tissue had biology character when humidity ratio was 50%,the results showed that the leaf tissue of S. jiangsuensis had powerful vitality and strong drought resistance. The S.jiangsuensis'194'of three strains had powerful resistance, S.jiangsuensis'172' and S.jiangsuensis'369'had faintish resistance, S.viminalis and S.sonjarica had lowest feebleness.
