摘　　要：根据安排在来舟林业试验场的试验及调查材料，对杉木种源、家系、人工林、杂交Ｆ＿１代中的灰杉、黄杉叶色类型比例进行比较分析；并对其生长表现、木材物理力学特性等进行了比较研究。结果表明：杉木的叶色类型遗传可能是由基因组控制的；杉木种源的叶色比例与生态环境有关，同一种源或家系内的灰杉、黄杉在中心产区同类立地上生长差异不大；黄杉可能具有较强的适应性。According to the experiments and investigation data from Laizhou Forest Experimental Farm ofFujian Province. comparative analyses were conducted on the leaf color type proport ion of Cunninghamia lanceolata CV. Glauca and Cunninghamia lanceolata CV.Mollifolia of the Provenances，families，Plantationsand cross F_1 of Chinese fir and comparative study was made on their growth performance and wood physicaland mechanical characteristics.The results showed that the heredity of leaf color types of Chinese fir wasprobably controlled by the gene group：the leaf color proportion of Chinese fir provenances was related totheir ecological environment：the adaptability of C.l．cv.mollifolia was probably stronger.
