摘要:
对山东省高密市栽植的7个杨树无性系的蒸腾速率及其影响因子进行了研究，结果表明：7个杨树无性系的气孔导度与蒸腾速率变化趋势基本一致，白天变化趋势均成单峰型，7个杨树无性系的最大蒸腾速率大小顺序为：I-107>NL95>L35>L323>中林46>中天杨>NL895，白天测定时段的平均蒸腾速率大小顺序为：I-107>L35>NL95>L323>中林46>中天杨>NL895，蒸腾速率与气孔导度的相关性最显著，气孔导度和蒸腾速率与各影响因子呈很好的多元线性函数关系，7个杨树无性系的蒸腾速率与树高、胸径和单株材积呈正相关关系。
Abstract:
The transpiration rate with their influencing factors was studied based on the observation and research of the samples selected from 7 varieties of poplar clones induced in Gaomi city in Shandong province. The results show that general daily changing tendency of 7 poplar clones is generally unanimous with single-apex curve. In addition, changing tendency of transpiration rates is just the same as that of the stomatal conductance. The daily the biggest transpiration rates are of the following order, TrI-107 > Tr NL95 > Tr L35 > Tr L323 > Trzhonglin46 > Trzhongtianyang > Tr NL895,The daily average transpiration rates are of the following order, Tr I-107 > Tr L35 > Tr NL95 > Tr L323 > Trzhonglin46 > Trzhongtianyang > Tr NL895. The mutuality between transpiration rate and stomatal conductance is the most prominent. The relationship between stomatal conductance and transpiration rate with their influencing factors are multivariate linear function, transpiration rates of 7 poplar clones have positive correlation with the H,D and V.
