摘要
对初选较好的27个种源,幼林期(4年生和6年生)在浙南龙泉和浙北桐庐的生长表现进行分析表明,目前生长最好的种源都来自马尾松互类产区,大多属南、中带种源区,其中桐棉种源以其生长季长和枝轮多的特性,在龙泉生长遥遥领先,且4年来未发现冻害;但在浙北幼年冻害严重,保存率不高,生长居中下水平。根据新复极差LSR检验,在Ⅰ2产区的龙泉仅相棉、信宜、古蓬、建阳和吉安5个种源生长突出,其余种源间差异不显著;在Ⅱ类产区的桐庐,来自Ⅰ类产区的种源大多表现出明显生长优势,与其它种源高生长差异极显著。建阳、武平、吉安、蒲江等种源在龙泉的生长名次随年龄而上升,说明有较强的适应性。
Abstract The growth was analysed of 27 selected fine provenances of Pinus massoniana in young tree stage (4-years and 6-years)in the South and north zhejiang province(Longquan and Tonglu).The best provenances at present were all from I class production region and most from the middle and southern provenance zone.of which,Tong mian provenance of Guangxi was the fastest one in Longquan for its long growing season and multi-wheel branches per year
