摘要
目的对不同气候地区乌天麻箭麻的生育期及农艺性状进行研究,为乌天麻有性种子培育提供参考依据。方法采用随机区组试验设计,进行室内盆栽试验,分析了不同气候条件对不同等级乌天麻箭麻生育期的影响,并对不同气候条件下乌天麻箭麻的农艺性状进行了多重比较、相关分析、多元回归分析和通径分析。结果对不同气候地区乌天麻的生育期分析表明,在昆明室内自然条件下进行乌天麻育种比在小草坝头道河室内自然条件下进行乌天麻育种可提前1个多月获得乌天麻种子。农艺性状多重比较与分析显示,不同气候地区不同等级乌天麻箭麻农艺性状存在一定差异。农艺性状变异分析表明,不同气候地区,相同级别的乌天麻箭麻其农艺性状变异系数差别不大。相关分析表明,不同气候地区,乌天麻箭麻各农艺性状间存在显著相关性。相关、通径和多元回归分析结果均表明,乌天麻单株花数是影响乌天麻箭麻单株蒴果数的最主要因子。结论从乌天麻箭麻的生育期及农艺性状分析数据上看,在昆明室内自然条件下进行乌天麻种子培育是可行的。
Objective The growth period and agronomic characters of Gastrodia elata Bl. f. glauca S. Chow were studied in different climatic regions,in order to provide data for sexual seed breeding of G. elata Bl. f. glauca S. Chow. Methods Randomized block design,indoor pot tests,mean comparison,variance analysis and comparative mapping were used to analyze the effects of different climatic conditions on the growth period and agronomic characters of G. elata Bl. f. glauca S. Chow. Results The analysis of growth period results showed that the seeds of G. elata Bl. f. glauca S. Chow were obtained 1 month ahead of schedule under the natural conditions in Kunming than in Xiaocaoba. The multiple comparison results showed that there were some differences in agronomic traits between the different grade G. elata Bl. f. glauca S. Chow in different climatic regions. The variation analysis results showed that there were little differences in agronomic traits between the same grade G. elata Bl. f. glauca S. Chow in different climatic regions. The correlation analysis,multiple stepwise regression analysis and path analysis results showed that the flower number per plant was the main factor affecting the number of capsules per plant of G. elata Bl. f. glauca S. Chow.Conclusion It was feasible to carry out the seed breeding of G. elata Bl. f. glauca S. Chow under the natural conditions in Kunming.
