盐胁迫对3种华南园林植物元素特性的影响
Elemental Characteristics of Three Landscape Species under Salt Stress in South China
摘要
Abstract
In order to select landscape plants with salt resistance, the allocation and accumulation of nutrient of three landscape species, such as Ervatamia divaricat, Excoecaria cochinchinensis and Duranta erecta, were studied under salt stress.Ervatamia divaricat,Excoecaria cochinchinensis and D.erecta were planted in College of Forestry and Landscape Architecture, South China Agricultural University. The results showed that Na content in all organs and K content in leaf, as well as Cl and N contents in all organs of Ervatamia divaricat and Excoecaria cochinchinensis increased, whereas K content in stems and branches of all plants and roots of Excoecaria cochinchinensis and D.erecta decreased under salt stress.P content of all plants varied irregularly.Na and Cl accumulations increased in three landscape species with salt stress, which enriched in stem and leaves. The N,P and K accumulations in different organs of Ervatamia divaricat and D.erecta and P and K accumulations in different organs of Excoecaria cochinchinensis decreased with salt stress.Therefore,NaCl stress increased Na and Cl contents and accumulations but decreased biomass of organ and N, P and K accumulations. Among the three species,Ervatamia divaricate and D.erecta were better landscape plants under salt stress in south China.关键词
