摘要
对泸县地区筛选的软枝油茶优良林分的生长性状、适应性及经济性状进行了跟踪观测,以期筛选出适应当地生产的软枝油茶优良单株。软枝油茶在泸县地区适生,并表现出生长快、早花早实等特点。软枝油茶实生林分存在较大差异,折算后单株鲜果产量和鲜出籽率最高可达6.90kg和42.14%,表明软枝油茶具有较大的改良价值。以单株鲜果产量、单位面积鲜果产量、鲜出籽率、干出仁率、种仁含油率为指标,对其进行主成分分析和隶属函数计算,初步筛选出了4个优良单株。
Through tracking observation on the growth characters, adaptability and economic characters of Camellia oleifera ＇ Ruanzhi＇ superior stands selected from Luxian, it was found that it grew normally and fast, early flowered and fruited in Luxian. Furthermore, there was a very significant difference between seedling stands. The fresh pod yield per plant and fresh seed rate could be up to 6. 90 kg and 42. 14% respectively after the discount, which showed that Camellia oleifera ＇ Ruanzhi＇ had a great improvement value. Taking fresh pod yield per plant, fresh pod yield unit area, fresh seed rate, and dried kernel yield and kernel oil rate as the indices ,4 superior individuals were selected preliminarily by the methods of principal component analysis and subordinative function analysis.
