摘  要:
从四川天麻主产区采集不同发育阶段的乌天麻块茎,测定其性状、产量和天麻素含量,并建立乌天麻不同类型块茎性状-产量-天麻素的相关回归方程。结果表明,与乌天麻块茎产量和天麻素积累呈正相关的因素主要有块茎干重(y2)、鲜块茎长度(x1)、鲜块茎直径(x3)、鲜块茎系数(y6)、鲜块茎周长(x2),呈负相关的因素主要为块茎数(x5)。

摘  要:
The tubers of Gastrodia.elata Bl.f.glauca S.chow in different developmental stages were colleted from major Gastrodia.elata Bl.production area in Sichuan Province,their characters,yield and gastrodin content were determined,and then the correlation regression equation of characters-yield-gastrodin content of different types of tuber was established.The results showed that the factors that had positive correlation with the yield of tuber and its gastrodin accumulation mainly were dry weight of tuber(y2),length of fresh tuber(x1),diameter of fresh tuber(x3),coefficient of fresh tuber(y6) and perimeter of fresh tuber(x2),and the factors that had negative correlation with the yield of tuber and its gastrodin accumulation mainly was tuber number(x5).
