我国黄连属植物较多,在相同条件下观察不同种黄连的生长发育变化不一样。为了探索它们之间对温度的关系,以利于栽培生产,本人作了3种黄连对耐温程度的试验。一、试验材料1.黄连(味连)Coptis chinensis Franch.移至重庆缙云山及南桐。2.三角叶黄连(雅连)C.deltoidea C.Y.Cheng et Hsiao.移至峨嵋山初殿附近。 There are many species of Coptis in China, and the growth and development of different species of Coptidis are different under the same conditions. In order to explore the relationship between them and the temperature, in order to facilitate cultivation and production, I made three kinds of test of the degree of temperature tolerance of Coptis. I. Test materials 1. Coptis chinensis Franch. was transferred to Chongqing Jinyun Mountain and Nantong. 2. Coptis Huanglian (Yalien) C.deltoidea C.Y.Cheng et Hsiao. Moved to the vicinity of the Shushan First Temple.
