The random-pollinated seeds of dominant fir trees were collected in 1977 and bred in 1978. Through basis of investigation to 15 characters of the progeny test forest established in 1979, it was found through variance analysis that genetic correlation was basically consistent with phenotype correlation. The ratio of crown to diameter Showed a negative relate with the of tree height, breast diameter and volume while the round number of shoots positive relate with them. The flowering behaviour of fir trees had a close relation with the positive genetic correlation of tree height, breast diameter and volume.

1977年采集了全县内选出的杉木优树自由援粉种子,于1978年育苗,1979年营造了子代测定林。1986年全面调查了其15个性状,用方差分析得出遗传相关与表型相关基本一致。冠径比与树高、胸径、材积三个主要经济性状呈遗传负相关,而枝盘数却与它们呈非常密切的遗传正相关。杉木开花习性与树高、胸径、材积三个主要经济性状的遗传正相关非常密切。

Cortical turpentine compositions of 69 individuals from 10 Pinus armandi seed sources originating throughout the range were analysed in a provenance test forest by a gas chromatography-mass spectra-computer combined instrument. The results showed that the turpentine contained in the farks of P. armandi were mainly monoterpene and sesquiterpene. The content of diterpene was detected as minor constituent. The significant geographic vatiations between total amounts of monoterpene and sesquiterpene, including...

Cortical turpentine compositions of 69 individuals from 10 Pinus armandi seed sources originating throughout the range were analysed in a provenance test forest by a gas chromatography-mass spectra-computer combined instrument. The results showed that the turpentine contained in the farks of P. armandi were mainly monoterpene and sesquiterpene. The content of diterpene was detected as minor constituent. The significant geographic vatiations between total amounts of monoterpene and sesquiterpene, including a-pinene dipentaene and hop alkene, and the latitutes of its provenance origin were observed. The trees from the Yunnan-Guizhou plateau seed provenance contained mainly monoterpene. On the contrary, the sesquiterpene was mainly contained in Qinling-Daba mountain seed provenance.

Soft X-ray is a new technique of testing seed quality.The technique and quantitative law for testing forest seed quality is explored theoretically and practically in this paper.The major photographic conditions are tube voltage,which relates to the thickness of seed and exposure value,which based on the tube voltage,focal distance and sensitive material.The keys of testing seed quality by X-ray contrast method(Xc method) are judging standards and the conditions of contrast,which have been given in this paper.In testing seed vigor of Pinus tabulaeformis Carr,two quantitative indexes are first determined,wich are the length of embryo and the germination ability of seed.Moreover,the quantitative model is established.

软X射线摄影是检验林木种子品质的一项新技术,本文力图从理论和实践上探索用X射线检验林木种子品质的技术及其数量化规律。摄影条件主要取决于管电压和曝光值,管电压与种子厚度有关,曝光值则依管电压、焦片距和感光材料不同而异;X射线衬比法(Xc法)检验种子品质的关键在于评判标准的制定以及衬比条件的选取;首次确定出用该法测定油松种子活力的两个数量化指标:种胚长度和Xc发芽能力,并建立了数量化模型。
