| 摘 要： | 利用９个生长较好的马尾松种源区域试验点测定材料，建立２４个种源在不同纬度上９年生树高的Ｇａｕｓｓｉａｎ反应函数，发现３个反应函数参数（模式纬度、内稳定性参数和尺度参数）具有显著的地理变异模式。北部种源大多在其原产地以南３～６个纬度的区域内生长表现最佳，而南部种源的原产地大致也是其生长的最适地。一般来讲，南部种源较北部种源具有较高的内稳定性和遗传可塑性，适宜栽植的区域较广。根据优良种源在不同纬度上的生长优势，并考虑到气候等安全因素，为几个马尾松优良种源确定了适合的推广栽植范围。

| Abstract: | The set of 9yearoldheight data of 24 provenances of masson pine (Pinus
massoniana Lamb,) from 9 regional trial locations with good growth was used to
establish height response function for each provenance grown at different latitudes.It
was observed that three response function parameters including mode
latitude,homeostatic parameter and scale parameter were strongly related to provenance
latitude.For the northern seed sources, mode latitudes were more than 36 below latitudes
of origin,whereas the southern seed sources attained best growth at latitudes near their
origin.In general,larger estimate for a homeostatic parameter and scale parameter was
obtained for the southern seed source ,compared with the northern seed source.The
sounthern provenances were less sensitive to environmental changes if planted over
good sites.Considered the vigours in height growth of various provenances extended in
different latitudes and the safe factors in seed transfer,the range of suitable planting
site was determined for several famous superior provenances of masson pine. |
