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.

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。

The behaviors of ten families of free loss flower of Zelkova schneideriana were compared in Nanjing district ,China,during 1999 2000.The results showed that there were significant difference between progenies in 1 000 seed weight,seed germination energy after 8 d for sowing (the seed with stratification treatments in winter),seed germination rate,shoot length and diameter(ground),branch number,and leaves color in autumn(1 yr old).Variation ranged from 15 0% to 50 0% in seed germination rate,35...

The behaviors of ten families of free loss flower of Zelkova schneideriana were compared in Nanjing district ,China,during 1999 2000.The results showed that there were significant difference between progenies in 1 000 seed weight,seed germination energy after 8 d for sowing (the seed with stratification treatments in winter),seed germination rate,shoot length and diameter(ground),branch number,and leaves color in autumn(1 yr old).Variation ranged from 15 0% to 50 0% in seed germination rate,35 8 cm to 52 9 cm in shoot length(in plastic film tubes)among ten families,and 92 9 cm to 123 9 cm in shoot length(in nursery)among four families.No.1 family had a superior growth.In autumn,the seedlings leaves turned to red or orange or yellow,each family with no single color.But the seedling number ratio of different color family was related to mother trees.

对榉树自由授粉的半同胞家系育苗及苗期变异研究结果表明 ,10个榉树家系间种子千粒重、发芽势、场圃发芽率、苗高、地径、1级侧枝数和秋季叶色变化等性状均有显著变异 ,其中 1号家系苗木生长量最大 ,红色叶植株比例高达 80 %。各个家系均含有红、红黄和黄色 3种叶色的植株 ,但不同叶色植株比例与母树秋叶叶色具有一定的相关性。同时 ,对加强榉树种质资源保护和选择改良工作进行了探讨
