After 30 days, the period of bloom of chrysanthemum, the content of malondialdehyde (MDA), the activity of peroxidase (POD) and superoxide dismutase (SOD), and the chlorophyll(a+b) in the leaves were determined. Results show that with the treatment of chrysanthemum plants by both chemicals NaCl and CaCl2, as compared with the treatment by NaCl only, the flowering period is increased by 2 days, the fresh weight/dry weight ratio is increased by 7.2%~33.3%, the content of POD is increased by 17.4%~67.8%, and the activity SOD is enhanced by 1.4%~2.7%, the chlorophyll(a+b) content is increased by 10.7%~70.0%, but the content of
MDA is decreased by 6.6%~26.0% in leaves. It is concluded that: (1) The application of 0~2mmol/L of exogenous calcium under salt stress would enhance the activity of SOD and POD remarkably. Decrepitude degrees of the cell membrane could also be alleviated distinctly. 2mmol/L of exogenous calcium is the best concentration to prolong the floral organ's life span. (2) The application of exogenous calcium under salt stress would prolong the profuse flowering period of chrysanthemum for about 2 days at the concentration of 1mmol/L of CaCl2.
(3) In the mean time, under salt stress, the application of exogenous calcium could increase chlorophyll contents in the new leaves of chrysanthemum. In a word, this experiment shows that exogenous calcium could enhance salt tolerance of chrysanthemum plants, and 1mmol/L of CaCl2 produces the best effect., authors=null, authorsList=null,

articleAbstract=为了探索外源钙能否缓解盐胁迫对栽培菊花的伤害及其适宜浓度，提高盐渍条件下菊花的栽培品质，以不同浓度的外源钙（CaCl2）搭配150mmol/LNaCl溶液分别浇灌盆栽菊花植株，研究盐胁迫条件下外源钙对菊花形态和生理效应的影响。结果表明，在NaCl胁迫条件下，经CaCl2处理植株较无CaCl2处理植株（对照）盛花期延长2d；处理30d后，植株鲜重/干重比值增加7.2%～33.3%；叶内丙二醛（MDA）含量降低6.6%～26.0%；过氧化物酶（POD）活性增加17.4%～67.8%；超氧化物歧化酶（SOD）活性增加1.4%～2.7%；叶绿素（a+b）含量增加10.7%～70.0%。外源CaCl2显著提高了盐胁迫下的菊花抗性，其中以1mmol/L CaCl2效果最佳。, authors=^{米银法，王进涛，朱 坤}, authorsList=米银法;王进涛;朱 坤, authorCompany=河南科技大学林学院，河南洛阳 471003, correspAuthors=null, authorNote=null, correspAuthorsNote=米银法, copyrightStatement=null,
