比较不同树形及树冠不同部位核桃各类枝条枯枝率、枝条粗度以及可溶性蛋白和总酚含量的差异,分析核桃枝条干枯与可溶性蛋白含量和总酚含量的关系。结果表明:自然圆头形、纺锤形和疏散分层形核桃树枯枝率均在树冠内膛达到最高,树冠外围最低;在树冠内膛和中部自然圆头形核桃树枯枝率极显著高于纺锤形和疏散分层形核桃树,而在树冠外围3种树形枯枝率均无显著性差异。纺锤形核桃树≤5 cm、>5~20 cm以及>20 cm枝条粗度在树冠内膛、中部和外围均达到最高,自然圆头形这3类枝条粗度在树冠内膛、中部和外围均最低;自然圆头形、纺锤形和疏散分层形核桃树≤5 cm、>5~20 cm以及>20 cm枝条粗度均在树冠外围达到最高,在树冠内膛这3种树形各类枝条粗度均最低;3种树形核桃树在树冠内膛、中部和外围>20 cm枝条粗度最高,≤5 cm枝条粗度最低。纺锤形核桃树≤5 cm、>5~20 cm和>20 cm枝条可溶性蛋白含量和总酚含量在树冠内膛、中部和外围均达到最高,自然圆头形核桃树这3类枝条可溶性蛋白含量和总酚含量在树冠内膛、中部和外围均最低;自然圆头形、纺锤形和疏散分层形核桃树≤5 cm、>5~20 cm和>20 cm枝条可溶性蛋白含量和总酚含量均在树冠外围达到最高,在树冠内膛3种树形各类枝条可溶性蛋白含量和总酚含量均最低;3种树形核桃树在树冠内膛、中部和外围≤5 cm枝条可溶性蛋白含量和总酚含量均高于其它两种类型枝条可溶性蛋白含量和总酚含量,>20 cm枝条总酚含量最低。3种树形核桃树树冠内膛各类枝条粗度、可溶性蛋白含量和总酚含量最低,枯枝率最高;树冠外围各类枝条粗度、可溶性蛋白含量和总酚含量最高,枯枝率最低。纺锤形核桃树树冠不同部位各类枝条粗度、可溶性蛋白含量和总酚含量最高,枯枝率最低;自然圆头形核桃树树冠不同部位各类枝条粗度、可溶性蛋白含量和总酚含量最低,枯枝率最高。随着枝条长度增加,枝条粗度升高,可溶性蛋白含量和总酚含量降低。 The differences of branchage rate, branch diameter, soluble protein content and total phenolic content of walnut in different parts of tree and crown were compared. The relationship between branching and soluble protein content and total phenolic content was analyzed. The results showed that the dead branches rate of natural round head, spindle and scattered layered walnut tree were the highest in the crown of canopy and the lowest in the outer canopy. In the crown and the middle of the crown, the percentage of dead branches in natural round walnut tree was extremely high There was no significant difference in spindle shape and evacuated dendritic walnut tree, but there were no significant differences among the three dendrite branches in crown periphery. Spindle walnut tree ≤ 5 cm,> 5 ~ 20 cm and> 20 cm branches in the crown crown, the middle and the outer reaches the highest, the natural round shape of these three types of branches in the crown crown, middle and periphery Which were the lowest among the three tree species in the canopy of the canopy. The diameter of the natural round-shaped, spindle-shaped and evacuated layered walnut trees ≤5 cm,> 5 ~ 20 cm and> The thickness of the branches was the lowest. The thickness of the branches of the three kinds of tree was the highest at the middle, the middle and the periphery of the crown, the diameter of the branches was less than 5 cm. The soluble protein content and total phenolic content of spruce tree walnut trees ≤5 cm,> 5 ~ 20 cm and> 20 cm were the highest in the middle, middle and outer canopies. The soluble protein content of the natural round walnut trees And total phenolic content were the lowest in the middle and outer canopies. Soluble protein content and total phenolic content of branches with natural round, spindle and scattered layered walnut trees ≤5 cm,> 5 ~ 20 cm and> 20 cm Which reached the highest level in the periphery of tree crown. The content of soluble protein and the total phenolics of the three tree branches in crown were the lowest. The content of soluble protein in the trunk, middle part and periphery of tree crown was less than 5 cm Total phenols content was higher than the other two types of soluble protein content and total phenol content,> 20 cm total phenolics lowest. The diameter of the branches, the content of soluble protein and the total phenolics were the lowest in all kinds of tree branches, and the percentage of dead branches was the highest in all kinds of tree branches. The diameter of branches, the content of soluble protein and the total phenols were highest in the periphery of crown, . The spindle diameter, the soluble protein content and the total phenolic content were the highest in the different parts of canopy of the spindle walnut tree, with the lowest rate of dead branches. The diameter, soluble protein content and total phenolic content of branches in different parts of the natural round walnut tree crown were the lowest , The highest branch rate. With the increase of shoot length, the shoots increased in coarseness, and the content of soluble protein and total phenol decreased.
