盐碱胁迫下闽楠和楠木的抗性生理研究

Research on Resistance Physiology of Phoebe Boumei and Phoebe nanmu under the Saline Alkaline Stress

摘要:

摘要：采用闽楠和楠木两个物种作为试验材料，配制4种不同浓度的盐碱溶液：200，100，50，0（对照）mmol·L-1，模拟重度盐碱、中度盐碱、轻度盐碱。研究在不同盐碱胁迫条件下闽楠和楠木生理生化指标的动态变化。试验＞结果表明：楠木的最高耐盐浓度是100 mmol·L-1,闽楠的最高耐盐浓度是200 mmol·L-1，可见闽楠相比于楠木具有较好的耐盐碱适应能力。

Abstract:

Abstracts:We selected Phoebe bournei and P.nanmu as the experimental materials,and treated them with 0,50,100,200 mmol·L-1 saline Alkaline Stress solution respectively to imitate light,middle and high level of saline Alkaline Stress.The physiological,biochemical data,and its dynamic change of P.bournei and P.nanmu in the condition of different saline alkali stress were studied.The results showed that the highest salt alkaline tolerance concentration of P. bournei and P.nanmu was respectively.
