摘要: 为研究不同红椿种源在不同地区的适应性和生长特性,筛选出湖北省较适宜的优良种源,对6 个不同种源的红椿在武汉地区生长表现的苗期叶片性状及地径和株高生长量性状进行了测试和相关分析。结果表明,无论是地径、株高,还是复叶长宽、小叶长宽和小叶数,不同种源间都存在极显著差异。综合地径和株高生长量数据,在武汉地区表现较好的种源为江西武夷山种源和江西官山种源,其次是福建来舟种源。对各测试性状进行相关性分析,结果表明叶片大小与地径和株高呈显著正相关,地径和株高也呈显著正相关,相关系数超过0.9;同时,地理纬度除与小叶数呈正相关外,与其他因子均呈不显著负相关,但地理经度除与小叶数相关不显著外,与其他因子均呈显著正相关。

Abstract: To study the adaptability and growth characteristics of different provenances of Toona ciliate in different regions, and select the suitable provenance in Hubei Province, the analysis of seedling leaf traits and diameter and height growth from 6 different provenances of Toona ciliata in Wuhan was carried out. The results showed that concerning diameter growth, height growth or length and width of compound leaf, length and width of leaflet and number of leaflets, there were extremely significant differences among different provenances based on the results of ANOVA. The better provenances were selected based on the integrated data of diameter and height growth, which were Jiangxi Wuyishan provenance and Guanshan provenance, followed by Fujian Laizhou provenance. The correlation analysis of the tested traits indicated that the leaf size was positively correlated with diameter and height growth, and the diameter was also positively correlated with height and their correlation coefficient was more than 0.9. Meanwhile, geographical latitude was nonsignificantly and negatively correlated with all traits except for the number of leaflets, which was positively correlated with latitude. But longitude was significantly and positively correlated with all traits, with the exception of the number of leaflets.
