天麻质量与有性杂交态势关系的研究

Study on Quality and Sexual Hybrid Penetration in Gastrodia Elata

通过对不同质量的麻种进行栽培 ,对其株数、茎粗、株穗长、有效开花数、株有效数和成果率进行观察统计 ,并通过方差分析和通径分析 ,结果表明 ,不同天麻质量对有性杂交态势存在着极显著的影响。有性杂交态势性状对成果率的影响差异明显。

By the cultivation of the different quantity Gastrodia Elata,observe and statistic it's quantity、stem diameter、stem length 、fringe length 、effctual blossom、effectual quantity、yield rate,then analysed by the method of Analysis of Variance and Path Analysis.It is manifested that:the mother Gaxtrodia elata's different quality have obvious influence to Sexual hybridization situation which influence yield rate the difference is obvious.So the mother Gastrodia elata that choice quantity is a key for Sexual hybridization.
