摘要
对7个金丝楸无性系的幼苗主要光合生理指标进行了研究,结果表明:7个无性系的光合速率(Pn)、蒸腾速率(Tr)、气孔导度(Gs)之间差异明显,日变化曲线依据变化趋势,可分为4种类型。蒸腾速率与气孔导度日变化趋势相同,呈正相关。
The study was conducted on the main photosynthetic physiological indicators of seedlings from seven clones of tCatalpabungei‘jinsiqiu’.The results showed that there were significant differences in photosynthetic rate(Pn),transpiration rate(Tr),and stomatal conductance(Gs)among the seven clones,and the daily variation curves could be divided into four types based on the trend of change.The transpiration rate is positively correlated with the variation trend of stomatal conductance days.
