摘  要：
[目的]为长春花的规范化生产提供理论依据。[方法]采用随机区组设计,测定长春花的农艺性状和总生物碱含量的动态变化。[结果]长春花农艺性状的动态变化呈现类抛物线型增长。其中株高和一级侧枝数目在4月中下旬就进入快速增长期,株高增速可达11.9cm/10 d,一级侧枝数目增速可达6.4条/10 d;而地径、叶片数目和干、鲜重则于5月下旬或6月上旬进入快速增长期,地径、叶片数目和干、鲜重最快增速分别为1.17cm/10 d、24片/10 d和2.27、15.30 g/10 d。总生物碱含量于6月中旬进入快速增长期,增速可达1.70mg/10 d。[结论]长春花农艺性状都呈现类抛物线型变化,表现为"前期增加缓慢-中期迅速增加-后期缓慢增加"的趋势,总生物碱含量则呈现前期缓慢增长,到6月中下旬进入快速增长期的趋势。

摘  要：
[Objective] The theoretic basis of the standardization production of madagascar periwinkle(Catharanthus roseus) was provided through the study.[Method] The dynamic change of main agronomic traits and the content of total alkaloids of madagascar periwinkle were measured with the randomized block design.[Results] The results showed that the dynamic change of agronomic traits was a parabolic growth.The plant height and the number of the first lateral branch had a faster increment from the middle or last ten-day of April,with the growth rate of the plant height: 11.9 cm/10 days and the number of the first lateral branch: 6.4 branches/10 days.The rapid growth period of terrestrial stem,number of leaf and dry/fresh weight of the plant was from last ten-day of May or the first ten-day of June,with the growth rate of terrestrial stem: 1.17 cm/10 days;the number of leaf: 24 leaves/10 days and the dry or fresh weight of the plant: 2.27 g or 15.30 g/10 days.The rapid increasing time of total alkaloids content appeared in the second ten-day of June,with the increasing rate: 1.70 mg/10 days.[Conclusion] There was a parabolic line in the process of madagascar periwinkle growth,with firstly,slow;then rapid and finally slow growth.The content-increasing of total alkaloids was slow at beginning of growth period and a rapid from the middle of June.
