【摘要】 应用ＰＶ技术对油松、侧柏等８种针叶树的抗旱生理指标进行了研究。结果表明，ＰＶ技术可以快速准确测定植物的某些水分参数；８种针叶树抗旱性排序为：侧柏＞油松＞杜松＞圆柏＞云杉＞柳杉＞雪松＞水杉；要全面研究植物的抗旱性，应在ＳＰＡＣ系统中研究植物生理、生态特性及解剖学特点。更多还原

【Abstract】 The physiological indexes of drought-resistance to eight species of conifer(Pinus tabulaeformis,Platycladus orientalis,etc) have been studied by means of PV technique.The results showed that some water parameters of plants may speed and accurate measured by PV technique.The drought-resistance order of eight species is:Platycladus orientalalis>Pinus tabulaeformis> Juniperas rigida>Sabina chinese>Picea asperata>Cryp tomeria fortunei>Cedrus cleodura>Metasequoia glyptostroboides.For the further drought resistance study,the physiological and ecological and anatomical characteristics in SPAC system shall be added.更多还原
