[Salt-tolerance evaluation of seedlings of medicinal Chrysanthemum morifolium cultivar].
OBJECTIVE
To evaluate salt tolerance of seedlings of 4 medicinal C. morifolium cultivars to be transplanted, and to expand the planting area.


METHODS
Seedlings were cultivated in hoagland nutrient solution containing various concentrations of NaCl for 30 days. The height, dry weight and chlorophyll content were investigated. Identification index mainly in relative growth rate, the evaluation of NaCl effects on the growth, K+, Na+ and Cl- distribution in seedlings were surveyed.


CONCLUSIONS
The salt tolerance was difference among four cultivars of C. morifolium. The salt tolerance of "Dabaiju" and "Changbanju" was weak, while "Hongxinju" and "Xiaobaiju" was strong. "Hongxinju" and "Xiaobaiju" may be planted in salinte soil area.
