摘要(Abstract):

该研究对云南昭通彝良县7个不同产区栽培乌天麻箭麻的9个农艺性状进行测定,并进行多重比较、相关分析、多元回归分析和通径分析,以期为昭通天麻品质控制和品种选育提供指导。农艺性状多重比较与分析显示,昭通天麻各农艺性状均存在一定程度的变异,其中单个块茎鲜重、环间距和肚脐眼直径变异较大,变异系数接近或超过20%;块茎长、块茎宽、块茎厚、点状横环纹环数和块茎长宽比变异较小,变异系数接近10%,点状横环纹环数、块茎长宽比两性状指标在不同产区间没有差异。相关分析表明,昭通天麻单个块茎鲜重与块茎长、块茎宽、块茎厚呈极显著正相关。通径分析和多元回归分析表明块茎长、块茎宽和块茎厚是影响昭通天麻地下块茎产量的主要因子,是乌天麻高产最佳的农艺性状指标。昭通乌天麻生产上,可将块茎长、块茎宽和块茎厚作为高产品种选育的性状指标,将点状横环纹环数和块茎长宽比作为道地药材品质控制的性状指标。
To provide guidance for quality control and variety breeding of Gastrodia elata f. glauca cultivated form in Zhaotong,nine agronomic traits of G. elata f. glauca cultivation form were measured and the traits were analyzed using multiple comparison,correlation analysis,multiple stepwise regression analysis and path analysis. The results of multiple comparison and analysis showed that the number of dot ring and the length-width ratio of tuber were no different in G. elata f. glauca cultivation form. The coefficient of variation about the single tuber fresh weigh,ring spacing and belly button diameter was about 20%. The coefficient of variation about the length of the tuber,the width of the tuber,the thickness of the tuber,the length-width ratio of tuber and the number of dot ring was near 10 %. The correlation analysis results showed that the single tuber fresh weigh and the length,the width and the thickness of the tuber were extremely significant positive correlated. The results of multiple stepwise regression analysis and path analysis showed that the length,the width and the thickness of the tuber were the main factors affecting the fresh weight of single tuber,which were the best agronomic traits on high yield of G. elata f. glauca. The length of the tuber,the width of the tuber and the thickness of the tuber,which would be used as indicators of the characteristics of high yield varieties in Zhaotong. The number of dot ring and the length-width ratio of tuber,which would be selected as quality control indicators of the genuine Chinese medicinal materials in Zhaotong.
