Study on selective breeding of medicinal Chrysanthemum morifolium / 中国中药杂志

<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>

Comparative study on internal quality of four cultivars of Chrysanthemum morifolium / 中国中药杂志

<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>
