摘　　要：为了了解新疆薄壳核桃叶片与果实性状间的相关性关系,对新疆地区树龄在10年以上的87株薄壳核桃实生后代叶片的5个性状、果实的17个性状进行调查与分析。结果表明:(1)叶片、果实性状指标间存在相关性。(2)叶片与果实性状间呈极显著正相关的有:叶长度与具青皮果重、青皮重,相关系数为0.36、0.37;叶面积与坚果湿重,青皮重,相关系数为0.33、0.37。(3)叶片与果实性状间呈显著正相关的有:叶长度与具青皮纵径、坚果湿重、坚果干重、壳厚,相关系数为0.23、0.21、0.25、0.21;叶面积与具青皮纵径、坚果干重,相关系数为0.21、0.23。(4)叶长、叶宽、叶面积与出仁率呈显著负相关,相关系数分别为-0.24、-0.23、-0.27。(5)叶型指数、叶厚度与果实性状相关性不显著。通过研究核桃叶片的长宽及叶面积来评价果实部分性状,可缩短核桃优良品种鉴定的时间。In order to well understand the relationship between leaf and fruit traits of thin-skinned walnut in Xinjiang,in this paper,87 walnuts trees age above 10 year were selected,five leaf traits and seventeen fruit traits were investigated and analyzed. The results showed that,（ 1） there was significant correlation between leaves and fruit traits.（ 2） There were great positive significant correlations between the leaf length and green peel weight,green tare weight with the coefficient of 0. 36 and 0. 37 respectively,between the leaf area and nut dry weight and Green tare weight with that of 0. 33 and 0. 37 respectively.（ 3） There were positive significant correlations between leaf length and green fruit longitudinal,nut dry weight,nut dry weight,and nut skin thickness,which were 0. 23,0. 21,0. 25,and 0. 21 respectively,positive significant correlations between leaf area and nut fresh weight and the green skin weight,and the correlation coefficients were 0. 21,0. 23 respectively.（ 4） The leaf length,leaf width and leaf area were significantly negatively correlated with kernel rate,the correlation coefficients were-0. 24,-0. 23,-0. 27 respectively.（ 5） There were no significant correlations between leaf index,leaf thickness and fruit traits. Through the study of the length,width and leaf area of walnut leaves to evaluate the fruit-related traits,the identification of walnut fine cultivars could be shorten.
