摘要: 采用盆栽试验法,对盐胁迫下的花叶蔓长春(Vinca major cv.‘Variegata’)施加CaCl2处理,通过对各生理生化指标的测定并结合隶属函数分析,探讨CaCl2对花叶蔓长春盐胁迫的缓解作用。结果表明:在3 mg/g和4 mg/g盐胁迫下,CaCl2处理可使可溶性糖含量、SOD活性和POD活性显著或极显著增加;在4 mg/g盐胁迫下,根系活力、可溶性蛋白含量随施CaCl2浓度增加而上升;在各浓度盐胁迫下,CaCl2可使净光合速率显著增加。综合分析认为:在中、低盐浓度胁迫下(3、4 mg/g),CaCl2的缓解作用较大,浓度以10~20 mmol/L为宜;在高盐浓度胁迫下(5~7 mg/g),CaCl2的缓解作用较小。

Abstract: The physiological and biochemical indexes of Vinca major cv.‘Variegata’grown in pots under salt stress condition were determined and analyzed with the membership function after CaCl2 treatment, aiming at exploring mitigative effects of CaCl2 on salt(NaCl)stress. The results showed that soluble sugar content and activities of SOD and POD increased significantly or very significantly when the plants were treated by with CaCl2 with concentrations of 3 mg/g and 4 mg/g. With the increasing of CaCl2 concentration root activity and soluble protein content were enhanced under salt concentration of 4 mg/g CaCl2 treatment could increase net photosynthetic rate significantly under different salt concentrations. Conclusion could be drown from the comprehensive analysis that mitigative effects of CaCl2 will be enhanced under low or moderate salt stress(3、4 mg/g)and be weakened under the high salt stress(5-7 mg/g), and that the appropriate CaCl2 concentration used is from 10 to 20 mmol/L.
