　　以河北省农林科学院药用植物研究中心从半野生菊花种质中筛选培育的菊花新品种河北香菊为研究对象，研究了河北香菊生长发育和干物质积累规律。结果表明：根据河北香菊各器官生长变化及干物质积累特点，将河北香菊的生长分为5个时期，即幼苗期、苗期、蕾期、花期和越冬期。香菊的叶面积指数在幼苗期最低，苗期出现大幅度的增长，到9月18日叶面积指数达到最大（3.90），之后缓慢下降，花期下降至2.54。香菊植株干物质增长量与积累量在蕾期之前较小，进入蕾期后大幅度增加；植株干物质阶段积累率以花期最高，占全生育期干物质积累量的32.1％。全生育期中，香菊植株各器官干物质积累量占总干物质量的比例顺序为分枝（43.0％）＞叶（32.9％）＞主茎和根（16.7％）＞花蕾（7.4％）。

Taking chrysanthemum new variety Hebeixiangju as study object , which was screened from half wild chrysanthemum germplasm by Medicinal Plant Research Center of Hebei Academy of Agriculture and Forestry Sciences, the growth characteristics and dry matter accumulation of Hebeixiangju were studied.The results showed that according to the growth of different parts and the characteristics of dry matter accumulation of Hebeixiangju, the development of Hebeixiangju was divided into five stages, which including early seedlings stage, seedling stage, bud stage, flower stage and wintering stage.In early seedling stage the LAI of Hebeixiangju was the lowest, then was increased by a wide margin in seedling stage, and reached the highest (3.90) on September 18, after that the LAI was decreased slowly and dropped to 2.54 in flowering stage.The plant growth and dry matter accumulation amount had a substantial increase after bud stage and that was smaller before bud stage.The dry matter accumulation rate was the highest in flowering stage (32.1%) .In the whole growth period, the order of the dry matter accumulation amounts in different organs was branch (43.0%) >leaf (32.9%) >main stem and root (16.7%) >bud (7.4%) .
