研究了两种杨树无性系（ＮＬ８０１０５、ＮＬ８０３５１）和柳树在土壤涝渍条件下的生长及生理性状．结果表明，在涝渍胁迫下苗木根系数量减少，根系长度缩短，根活力下降；高生长降低；最终生物量明显减小；叶片气孔对涝渍胁迫有较强反应，叶片中硝酸还原酶（ＮＲ）活性也会受到一定影响．柳树与杨树之间存在较大差异，无论从生长还是生理性状看，杨树不如柳树耐涝．
The growth and physiological characteristics of two poplar clones (NL80105, NL80351) and willow under soil waterlogging were studied. The results showed that under the waterlogging stress, the root number of seedlings decreased, the length of root system decreased, the root vigor decreased, the height growth decreased, and the final biomass decreased significantly. The leaf stomata responded strongly to waterlogging stress. The content of nitrate reductase (NR) ) Activity will also be affected. Willow and poplar there is a big difference, whether from the growth or physiological traits, poplar as willow waterlogging.
