岩黄连种子繁殖研究

于2003年4月至2004年4月在广西植物研究所实验场内进行岩黄连(Coryd a lis sax icola Bun ting)种子繁殖试验。试验种子分为东兰类型、贵州类型和马山类型。试验前先测定种子的基本情况,然后以东兰类型的种子分别进行不同着生部位、贮藏方法、贮藏时间、播种基质试验。试验结果是东兰类型的种子发芽率最高,为27.75%,贵州类型的最差,仅为16.13%。播种基质以火土加肥泥的最好,种子发芽率为21.25%。种子贮藏以纸袋密封置于低温贮藏最好,发芽率为25.75%。种子以着生在果穗中部的发芽率最高,为28.75%,岩黄连选种时应注重保留中部种子。岩黄连种子没有休眠期,采收后即可播种,最好的播种期是4~8月份。

Seeding Propagation of Corydalis saxicola Bunting

The seminal propagation characteristics of Corydalis saxicola was studied in experiment field of Guangxi Institute of Botany from April of 2003 to April of 2004.The seed was divided into three types,named Donglan,Guizhou and Mashan.We measured the basic parameter of seed before experiment.The seed of Donglan was used for experiment of different part,store method,store time and base material.The results are as follows: the type of Donglan had the highest germination percentage,which was 27.75%.The type of Guizhou had the lowest germination percentage,which was 16.13%.The seeds sowed in a mixture of turfy soil and fertile soil,the seed of store under low temperature and the seeds on the middle part of fruit cluster had higher germination rate,which were 21.25%,25.75% and 28.6% respectively.Corydalis saxicola' seeds can be sow after harvest.The optimum seed sowing period is between April to August.
