摘要
以金果榄(Tinosporae Radix)基原植物青牛胆[Tinospora sagittata(Oliv.)Gagnep.]实生种子进行大棚育苗,并检测一、二年生金果榄种苗的农艺性状及二年生金果榄种苗干燥块根的古伦宾含量.对一年生金果榄种苗喷施MS营养液,检测其农艺性状并分析各性状之间的相关性.结果表明,金果榄种苗株高、主根长、块根随种植时间呈增长趋势,二年生苗叶片数在6-7月无明显增加;种苗叶形指数、块根形指数分别在5月龄、17月龄后无明显变化;二年生金果榄种苗干燥块根EP理论塔板数均>5 000、古伦宾含量均>2%,水分含量均<13.0%,符合药典规定.MS营养液处理促进了一年生金果榄种苗株高增长、叶片数增加和块根的形成,种苗株高、叶宽、茎粗与地下块根鲜重呈显著正相关,块根鲜重与块根纵径、块根横径、块根形指数呈显著正相关,块根横径、块根纵径、块根形指数之间均呈极显著正相关.叶形指数与叶长、叶宽之间无相关关系,而块根形指数与块根纵、横径之间呈正相关.
Abstract
The seeds of Tinospora sagittata(Oliv.)Gagnep.,the original plant of Tinosporae Radix,were grown in the greenhouse,and the agronomic traits of the annual and biennial Tinospora sagittata(Oliv.)Gagnep.seedlings and the content of columbin in the dry block roots of the biennial Tinospora sagittata(Oliv.)Gagnep.seedlings were detected.MS nutrient solution was sprayed on the an-nual Tinospora sagittata(Oliv.)Gagnep.seedlings to detect their agronomic characters and analyze the correlation between the charac-ters.The results showed that the plant height,taproot length and block root increased with planting time,while the leaf number of bi-ennial seedlings did not increase significantly from June to July;leaf shape index and block root shape index had no significant change after 5 months of age and 17 months of age,respectively;the theoretical number of EP plates,the content of columbin and the water content of the dried block roots of the biennial Tinospora sagittata(Oliv.)Gagnep.seedlings were all>5 000,>2%and<13.0%,re-spectively,which were in line with the provisions of pharmacopoeia.The seedling height,leaf number and block root formation of an-nual Tinospora sagittata(Oliv.)Gagnep.seedlings were increased under MS nutrient solution treatment,respectively.And plant height,leaf width and stem diameter were significantly positively correlated with underground block root fresh weight,block root fresh weight was significantly positively correlated with block root longitudinal diameter,block root transverse diameter and block root shape index,and block root transverse diameter,block root longitudinal diameter and tuber shape index were extremely significantly posi-tively correlated with each other.The leaf shape index had no correlation with leaf length and width,but the block root shape index had positive correlation with longitudinal diameter and transverse diameter of block root.
