石刁柏雌雄株产量构成与品质差异的研究

本文对石刁柏雌雄株产量构成及产品品质等经济性状进行了分析。研究发现，雄株生长快，产量高，其产量构成为茎数型；而雌株则以单茎重为主，属茎重型。单茎重与幼茎粗度呈正相关关系，直线回归方程为Ｙ雄＝６９．７０Ｘ－４４．４２，Ｙ雌＝５０．３５Ｘ－２５．０９．品质指标除氨基酸外，雌雄间无显著差异；生产上宜选用优良雄株，并促进幼茎肥大，以提高其商品价值。

Studies on the differences of yield-make-up and quality betwesnmale and female plants of Asparagus officinalis L.

Several economical characters, i.e. the yield make-up and product qualities,of both male and female plants of Asparagus officinalis L. were analysed. The resultsshoAs that inale plants grew more rapidly and produce higher yield than femaleplants. The yield make-up of the male plant was a stem-nuxnber type, while that ofthe female plant being stem-weight one. The single stem weight was positivelycorrelative to its size, the regretion apuatioris were Ymale=69.70X-44.42,Yfemale=50.35X-25.09. There were no significant differences in quality indexes betweenthe two sexualities, exeept amino acids. We concluded that the male plant waspreferent for plantation, and measures to enhance the expansion of young stemswould increase the commercial value.
