摘要
本试验研究了福建省25个不同垂直、水平分布的马尾松天然群体的遗传变异,并对球果、种子形态,苗期生长和物候学等34个性状作了分析。研究结果表明,马尾松垂直分布的天然群体间存在丰富的变异;不同坡向上海拔变化大致趋势相近;垂直分布变异程度大于水平分布,但海陆效应超过纬度变化引起的效应,部分甚至超过海拔高度的效应。
Genetic variations between and within 25 masson pine's natural populations were studied in relation to their vertical and horizontal distributions in Fujian Province. Thirty-four traits were investigated and analysed, including cone and seed morphology, seedling growth, and phenology. The results suggested that there were great differences among natural populations of masson pine with vertical distributions. In both aspects, elevation populations had the same trend of variation. Variations in vertical distribution were greater than that in horizontal distribution, but sea-inland effect on the traits variations surpassed latitude and even elevation. According to the results, some suggestions were made for allocation and selection of masson pine seeds in Fujian.
