ABSTRACT
<p><b>OBJECTIVE</b>To investigate botanical characters and yield of four cultivars of Chrysanthemum morifolium for further study on their genetic diversity and selective breeding.</p><p><b>METHOD</b>The characters were observed and yield was investigated by field randomized block and analysis of variance.</p><p><b>RESULT AND CONCLUSION</b>The botanical characters are difference among four cultivars; the amount of single flower head is the main factor influencing on the output of Chrysanthemum morifolium (r = 0.925); the yield of "Hongxinju" and "Xiaobaiju" are remarkably higher than that of "Dabaiju" and "Changbanju".</p>

<p><b>OBJECTIVE</b>To evaluate salt tolerance of seedlings of 4 medicinal C. morifolium cultivars to be transplanted, and to expand the planting area.</p><p><b>METHOD</b>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.</p><p><b>RESULT AND CONCLUSION</b>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.</p>

<p><b>OBJECTIVE</b>To study organochlorine pesticide and heavy metal residuals of Chrysanthemum morifolium.</p><p><b>METHOD</b>The contents of organochlorine pesticide residuals was determined by chromatography, Cu, Pb, Cd was determined by AAS, and As, Hg was determined by AFS.</p><p><b>RESULT AND CONCLUSION</b>The contents of organochlorine pesticide and heavy metals residuals are up to "Green Trade Standards of Importing & Exporting Medicinal plants & Preprations" (MOFTEC, 2001), but the contents are different among four cultivars clearly.</p>

<p><b>OBJECTIVE</b>To study the genetic diversity of C. morifolium on the chemical constituents.</p><p><b>METHOD</b>Chemical constituents of four cultivars cultivated with the same conditions were compared in three types of index: chlorogenic acid, flavonoid and volatile oil.</p><p><b>RESULT AND CONCLUSION</b>With different cultivars and processing methods, the contents of chlorogenic acid, flavonoid and volatile oil extracted from C. morifolium vary great extent.</p>
