摘要：果枝率的高低和结果量的多少直接影响着果实产量,因此调查果枝及结果性状对于提高产量及经济效益至关重要。实验以山核桃为试材,研究了果枝及结果性状在不同无性系间(内)、不同树冠部位的差异性及相关性,结果表明:无性系的果枝率、结果枝数均有差异,大部分无性系的果枝率均在50.00%以上,徐坑4号的果枝率最高;22个无性系每枝结1个果和每枝结2个果的占多数,每枝结4个果的果枝仅占果枝的0.55%;大源4号、大源6号的7—8月落果率均低于其它无性系;大源4号、徐坑1号、徐坑88号的坐果率高于其它无性系,高岭3号、大源4号、徐坑2号的每母枝果枝数和每母枝结果数均较高;山核桃结果母枝的直径集中分布区为4.01～6.00 cm,在此分布区的结果枝数量占总数的66.53%,结果枝直径集中分布区为3.01～4.00 cm,在此分布区的结果枝数量占总数的63.82%;结果母枝直径与母枝长度成极显著正相关,结果母枝直径与结果枝直径成极显著正相关,结果母枝果数与每结果枝簇数为极显著正相关,每结果枝果数与每结果枝簇数为显著负相关。
The fruiting rate and fruit quantity affect the fruit yield directly.Therefore,investigating fruit branch and economic benefits is very important for improving the yield and fruit quality.The experiments used pecans as the test materials to study the differences and correlations of fruiting branches and fruiting traits among different clones,clones,and different tree crowns.The fruit branch rate and the number of fruit branches of the clones were different,The fruiting rate of most clones is above 50.00%.The rate of fruit was highest in Xukeng 4;The majority of each of the 22 clones with 1 fruit and 2 fruit per branch,and 4 fruit branches per branch were only 0.55%of the fruit branch;Dayuan 4,Dayuan 6,Gaoling 9 in April and August fruit drop rate is low;The fruit rate of Dayuan 4,Xukeng 88,Dayuan 6,Xukeng 1 is higher than other clones,The fruity rate of Dayuan 4,1,Xukeng 88 was higher than that of other clones,The number of each branch and the number of parental branches were higher in Gaoling 3,Dayuan 4 and Xukeng 2.Carya cathayensis fruiting branch diameter of the concentrated distribution area of 4.01~6.00 cm,the distribution of the number of bearing branch accounted for 66.53%of the total,the branch diameter concentrated distribution area is 3.01~4.00 cm,the region accounted for 63.82%of the total number of branches;Using K means clustering method for classification of the branch group walnut;Branch diameter and length was positively correlated,the diameter of fruiting branch and branch diameter was positively correlated with the number of fruit bearing branches per fruit branch number of clusters is significantly positively correlated with fruit number per fruit branch number per cluster results of significant negative correlation.
