摘　　要：通过对8个种源77个家系6年生火力楠人工林的生长及形质性状分析,选出优良的种源家系,为火力楠种质资源的合理开发利用提供科学依据。研究结果表明:广东信宜和广西浦北的2个种源与7、65、104、98和29号5个家系在闽南地区综合生长表现较优;在8个种源中,广东信宜的种源综合评定值排名最高,广西博白的综合评定值最低;在所有77个家系中,来自广东信宜的家系7综合排名最高,说明家系7在生长及形质性状上综合优势明显。因此,表现较优的2个种源和5个家系可用做闽南地区早期火力楠人工林种植的优良材料,其中最具潜力的家系7和家系65值得闽南地区早期火力楠人工林种植推广。研究结果可为闽南地区营造火力楠早期优质高效的人工林提供科学依据。To provide scientific bases for reasonable exploitation and utilization of germplasm resources,the superior provenances and families were selected based on analyzing the growth and shape traits of the 6-year-old Michelia macclurei artificial forest of 8provenances and 77families.The results showed that the two provenances Guangdong Xinyi and Guangxi Pubei andfive families(No.7,65,104,98 and 29)had good overall growth performance in Southern Fujian.Among all 8provenances,Guangdong Xinyi ranked the highest in the comprehensive evaluation,and Guangxi Bobai had the lowest comprehensive ranking.Among all 77families,the family No.7from Guangdong Xinyi ranked the highest,indicating that it has the obvious comprehensive advantage in growth and shape traits.Therefore,the 2 provenances and 5families with better performance can be used as excellent materials for planting early M.macclurei plantation in Southern Fujian,among which the most promising family No.7and family No.65 are worth promoting.The research results can provide the scientific basis for the construction of early high quality and efficient M.macclurei artificial forest plantation in southern Fujian.
