Abstract

In this study, Fuji apples (the Malus domestica Borkh.cv.Red with Fuji) / Malus hupehensis (Malus hupehensis) for test materials, Village in Yiyuan community, Zibo orchards, Shandong Agricultural University Fruit Experiment Station in 2007-2009. Measured by enzyme-linked immunoassay (ELISA) technology opened the perspective of potted Fuji apple shoot growth and endogenous hormone content and balanced; using ^{13 C ^{15 N stable isotope labeling method to study the impact of the opening angle of the carbon and nitrogen nutrition allocation of potted Fuji Apple; utilize ^{15 N labeling methods, branches sagging under field conditions in spring soil application of ^{15 13 C distributional impact of the research results show that the roots ^{13 C distribution rate with the opening angle increases reduce, control, the twigs level and branches drooping three groups roots 13C allocation rates fall tree growing season reached their respective maximum were 46.39%, 36.39%, 26.73%; leaves ^{13 C distribution rate with the opening angle increases and increased in autumn shoot growth period of three groups of blades 13C distribution rate were 30.15%, 42.40%, 54.97%; opened angle to reduce ^{13 C in the allocation of new shoots and fine roots, with the opening angle increases, weakened enhanced role. The aboveground ^{13 C distribution rate was the branches droop processing of gt; twigs level processing gt; perennial organs ^{control trends, aboveground 13 C distribution rate differences not significant. The findings of the opening angle of the distribution and utilization of 15N-urea angle increases to reduce plant 15N utilization, significant differences in the autumn shoots growing season, control was significantly higher than the treatment, control branches levels and branches drooping three were of 5.29%, 3.87% and 4.05%, respectively. In shoots vigorous and fall growing season, handling the shoots ^{15 N distribution rate significantly lower blade the 15N distribution rate was increased; Spring pause long-term process aboveground perennial organs and new Shoot ^{15 N distribution rate significantly lower than the control. Field trials, The Fuji apple branches drooping influence spring soil applied ^{15 N-urea uptake, utilization and allocation. Branches drooping the roots Ndff value lower than that of the control; difference to mature fruit from shoots prosperous long-term deal with short tip, and was born in the short shoot organ Ndff value with the control the other organs Ndff were lower than that of the control; fruit harvest after processing aboveground organs Ndff value is higher than the control. Branches droop impact on the organ ^{15 N allocation processing the short tip fruit ^{15 N distribution rate significantly higher than that of the control, long shoots ^{15 N distribution rate is lower than that of the control; processing the roots ^{15 N distribution rate higher than the control fruit enlargement period before the flower bud differentiation stage processing roots ^{15 N distribution rate is lower than that of the control the gap after harvest of 20.203%, the most significant difference. The branches drooping processing fruit trees ^{15 N utilization to reduce differences with the phenophase goes gradually increased after the fruit is harvested, processing and control ^{15 N utilization 21.083% and 26.495%.}}}}}}}}}}}}}}}}}}}
