摘　　要：通过对石刁柏四个品种花药培养后代 38个株系的初步研究 ,考察产量与出茎数、茎长、茎粗的相关性。结果表明 :1)花粉植株间的分离较小 ,性状间相关性的可靠性大于品种间植株的相关性。 2 )产量与三个性状的相关性都很显著 ,但依次为 :出茎数 ,茎粗 ,茎长。出茎数与茎粗也相关密切。 3)在培育粗茎的基础上提高出茎数可以显著提高石刁柏产量。The correlations between asparagus stem yield and stem number, stem length as well as stem thickness were examined through preliminary investigation on 38 progeny lines derived from anther culture of 4 asparagus varieties. The results are summarized as follows: 1. The character segregations are smaller among pollen derived plants than among varietal plants, so the reliabilities of correlations between characters among anther derived plants are greater compared to varietal plants. 2. The correlations between stem yield and three stem characters are all marked in the following order: stem number>stem thickness>stem length and the stem number is closely correlated also to stem thickness. 3. On the basis of growing thick stem, increasing stem number will raise markedly asparagus yield.
