4种蒲桃属植物幼苗耐涝能力分析

Analysis of the Tolerance to Flooding Stress from 4 kinds of Syzygium seedlings

采用模拟水淹胁迫方法,对方枝蒲桃(Syzygium tephrodes)、赤楠蒲桃(S.buxifolium)、轮叶蒲桃(S.grijsii)、肖蒲桃(S.acuminatissimum)等4种蒲桃属乡土植物进行水淹胁迫耐受能力试验。结果表明,4种蒲桃属植物均能在水分饱和和半淹胁迫下存活;综合生理指标数据进行隶属函数分析,得出4种蒲桃属耐涝能力排序为:方枝蒲桃>轮叶蒲桃>赤楠蒲桃>肖蒲桃。

In this paper,we take the water stress simulated method to test the flooding stress abilities of Syzygium tephrodes,S. buxifolium,S. grijsii and S. acuminatissimum. The results show that four syzygium plants can survive in the water saturated environmenu and half flooding environment. By integrating physiological index data for subordinate function analysis,The rank of flooding stress ability by four syzygium plants is S. tephrodes S. grijsii S. buxifolium S. acuminatissimum.
