摘要: 以2年生‘红灯’(Prunus avium L.‘Hongdeng’)/东北山樱(Cerasus sachalinensis Kom.)为试材,研究了不同短截程度对13C和15N分配和利用的影响。结果表明,新梢生长期,短截处理修剪促进了碳水化合物向根系分配,极重度短截处理使叶片和新梢中13C分配率分别减少了29.15%和7.3%,粗根和细根中13C分配率增加了46.65%和48.43%。随着时间的推移,短截处理的叶片和新梢的13C分配率均显著高于对照,多年生枝干的13C分配率随短截程度的增加而减小,根系的13C分配率以中短截最低,极重度短截最高。各处理15N利用率从高到底依次为中度短截 > 对照 > 极重度短截,在新梢停长期差别最大,3个处理15N利用率分别为6.91%、5.54%和3.60%;多年生枝干15N分配率随短截程度的增加而减小,短截处理叶片和新梢的15N分配率随短截程度的增加而增加。

Abstract: Two-year-old field sweet cherry trees(Prunus avium L.‘Hongdeng’/Cerasus sachalinensis Kom.)were used to study the effects of different cutting back pruning degrees on characteristics of distribution of 13C and 15N,and as well as utilization of 15N. The results showed that the cutting back pruning promoted the carbohydrates to root system distribution at the new shoot growing stage. The extremely heavy cutting back pruning reduced the 13C distribution ratios to the leaves and new shoots respectively by 29.15% and 7.3%,and increased the distribution ratios to the large and fine roots respectively by 46.65% and 48.43% With the tree growing process,the 13C distribution ratios in the cutting back pruning treatment's leaves and new shoots were higher than that in the control. The 13C distribution ratios in the perennial branches decreased with the increase of the cutting back pruning intensity. The 13Cdistribution ratios in roots were the lowest in the moderate cutting back pruning and the highest in the extremely heavy cutting back pruning. The sequence of the 15N utilization ratios from high to low was the moderate pruning > the control > the extremely heavy pruning. The maximum difference of 15N utilization efficiency appeared at new shoot stop growing stage,and the 15N utilization ratios respectively were 6.91%,5.54% and 3.60% in the moderate,the extremely heavy cutting back pruning and the control. The 15N utilization ratios in the perennial branches decreased with the increase of the cutting back pruning intensity and that in leaves and new shoots increased with the increase of the cutting back pruning intensity.

Key words: sweet cherry, cutting back pruning, 13C, 15N, distribution, utilization
