湖北省主栽杨树品种的苗期抗旱性评价
Evaluation of Drought Resistance at Seedling Stage for Major Poplar Cultivars in Hubei Province
摘要
Abstract
In order to screen out poplar(Populus L.)cultivars suitable for afforestation in arid areas of Hubei Province,eight main planted cultivars in Jianghan Plain,namely,P.euramericana'Nanlin 895',P.deltoides'Danhong',P.deltoides'Huashi 1',P.deltoides'Huashi 2',P.euramericana'I-214',P.deltoides'Harvard',P.deltoides'Zhongqian 3',and P.deltoides'Zhongshi 8'were selected,and their growth and physiological indicators were determined through drought stress experiments.The results showed that all poplar cultivars presented with growth inhibition and decreased photosynthetic efficiency.Among them,P.deltoides'Harvard'was the most severely affected,while P.deltoides'Huashi 2'was the least affected.The cluster analysis indicated that P.deltoides'Huashi 1'and P.deltoides'Huashi 2'had good drought resistance performances.The membership function analysis showed that the drought resistance ranking of the poplar cultivars was P.deltoides'Huashi 2'>P.deltoides'Danhong'>P.euramericana'Nanlin 895'>P.deltoides'Zhongqian 3'>P.deltoides'Huashi 1'>P.deltoides'Zhongshi 8'>P.euramericana'I-214'>P.deltoides'Harvard'.Therefore,P.deltoides'Huashi 2'had better drought resistance and was recommended for afforestation in arid areas of Hubei Province.It was advisable to avoid planting P.euramericana'I-214'and P.deltoides'Harvard',which had weaker drought resistance.This research could provide a reference for the selection of poplar afforestation cultivars in the arid areas of Hubei Province.关键词
