油桐果实、种子经济性状和种仁含油量的高低是衡量油桐产量高低的重要经济指标.因此,了解油桐果实、种子各性状之间的关系、油桐的含油率及其经济性状的优劣,这对油桐良种选育、基因资源的鉴定和利用具有一定的意义.本文就1980—1981年结合油桐优树选择,油桐果实种子收集,进行了这方面研究工作,取得了一定结果.现初步整理如下:一、材料和方法1.试验材料果实、种子性状的测定材料系省内1979—1980年选择的18株油桐优良单株;种仁含油率的测定除18个单株外还有初选,复选的28个单株及从外省湖南、广西、浙江、福建引进的7个品种类型或单株,
Tung oilseed, seed economic traits and seed oil content is an important economic indicator to measure the yield of tung tree.Therefore, to understand the relationship between the tung oilseed and seed traits, the tung oil content and its economic traits Which is of great significance to the breeding of elm seeds and the identification and utilization of genetic resources.In this paper, the research work on the selection of tung tree and the collection of the seeds of tung oil tree were carried out in 1980-1981, Some results are now sorted out as follows: First, the material and methods 1. Test materials Determination of fruit, seed traits of the province from 1979 to 1980 selected 18 tung tree fine individual strains of oil determination except 18 There are also 28 primary plants and 8 single plants which have been selected from the outside of the plant and 7 varieties or single plants introduced from other provinces such as Hunan, Guangxi, Zhejiang and Fujian,
