舟山海岛5种地被植物抗涝性研究

Experiment of Waterlogging Stress on Five Plant Species in Zhoushan

对柃木(Eurya japonica)、滨柃(E.emarginata)、厚叶石斑木(Rhaphiolepis umbellata)、赤楠(Syzygium buxifolium)、钝齿冬青(Ilex crenata f.crenata)5种地被植物进行水淹试验,研究5种植物水淹后的症状出现时间、植株死亡时间、伤害后的植株复活率、水淹胁迫后植株游离脯氨酸变化,通过隶属函数的方法进行抗涝能力综合评价,结果表明:同等水淹条件下,5种植物抗涝能力从大到小依次是厚叶石斑木>赤楠>滨柃>钝齿冬青>柃木。

Experiments of waterlogging stress were conducted on 3-year container seedlings of Eurya japonica,E emarginata,Rhaphiolepis umbellate,Syzygium buxifolium,Ilex crenata f.crenata.The result demonstrated occurrence of symptoms and death,recovery rate after waterlogging treatment,change of free proline content.Integrated evaluation of anti-waterlogging of tested plant species by membership function resulted that the order was：Rhaphiolepis umbellate＞ Syzygium buxifolium＞ E.emarginata ＞ llex crenata f.crenata ＞ E.japonica.
