摘要/Abstract

摘要： 收集13个核桃楸种源，在黑龙江省林口和兴隆两个试验点进行播种育苗，调查1年生苗木生长量，进行核桃楸种源选择试验。结果表明，不同种源核桃楸在两地播种后，苗高、基径生长量差异显著，适合林口地区的优良种源为绥阳、和龙、帽儿山和辉南种源；适合兴隆地区的优良种源为抚松、和龙、兴隆和绥阳种源。林口试验点核桃楸种子直径与1年生苗木基径生长量的相关系数达到了显著水平，可以作为反映基径生长量的指标，用线性函数模型来模拟核桃楸种子与苗木的生长情况的相关系数和拟合度相对较高。通过对13个种源地和2个试验点的主要环境因子差异与其1年生苗生长性状差异相关性分析，核桃楸不同种源1年生苗高与纬度和年平均气温等环境因子有一定相关性，且呈负相关，核桃楸种源可适当向北移栽。

Abstract: A selective experiment on 13 Juglans mandshurica provenances was conducted in Linkou and Xinglong of Heilongjiang province by investigating the growth of one-year-old seedlings. The results showed significant differences in height and basal diameter growth of the provenances in the two test-sites. The excellent provenances adapted to Linkou area was Suiyang, Helong, Maoershan and Huinan. The excellent provenances were Fusong, Helong, Xinglong and Suiyang in Xinglong area. There was a significant correlation between the seed diameter and basal diameter growth of J.mandshurica in Linkou area. It could be regarded as the index of reflecting the basal diameter growth. The relationship between the growths of seed and seeding could be best described by the linear model. The correlations between the one-year-old seedlings growth of J.mandshurica and the main environmental factors of 13 provenances as well as two test-sites were analyzed. The results showed the height of one-year-old seedlings has a significantly negative correlation with the latitude and the annual temperature of locations. The provenances of J.mandshurica may be appropriately planting northwards.
