| 摘 要： | 抗蒸腾剂是减少水分损失的一种新型的抗旱化技术,为了解其对欧美杨的影响,以1年生苗木为研究对象,通过喷施不同浓度的黄腐酸处理,结果表明,质量浓度为3.5g/L的处理效果最好,其气孔导度和蒸腾速率分别比对照降低了42.0%和38.8%;对光合作用有促进作用;对欧美杨的叶水势提高幅度为13.8%,能显著抑制叶水势的下降.

| Abstract: | Influence of FA on photosynthesis and transpiration rate of Populus Euramericana was researched.The result showed the effect of FA of 3.5 g•L-1 is the Best,which reduced stomatal conductance and transpiration rate by 29.1% and 26.3% Respectively; FA could promote photosynthetic rate;The leaf water potential was improved by 14.3%,it had an obvious prohibiting effect on the decrease of leaf water potential. |
