项目摘要

Translocation of ィイD113ィエD1C-photosynthates for about 44 to 72 hours after ィイD113ィエD1COィイD22ィエD2 exposure was investigated between 2-year-old branches on mature trees during the each rapid growth stage of cherry, pear, apple and Japanese persimmon fruit. Further, The ringings were treated to the bases of different ages of branches, and the growth of the fruits and the stems were compared with the controls. Growth and qualities of fruits on the ten 3-year-old branches in mature apple 'Fuji' trees were investigated in relation to their light environments.1. The proportion of total ィイD113ィエD1C translocated from the branch fed with ィイD113ィエD1COィイD22ィエD2 toward the other branches within the 3-year-old branch was distributed from 2.5 to 27% in the cherry, from 5 to 29% in the pear, from 0.5 to 16% in the apple and from 0 to 31% in the Japanese persimmon. These proportions were higher than that of the experiments where the 3 or 4-year-old branches were fed with ィイD113ィエD1COィイD22ィエD2.2. There was no large difference of final diameters both the fruits and the branches between the most of the ringing treatments and the controls. And, the effect of the difference of the age of the treated branch did not become clear in each species. The each correlation between the each of the 4 species of light environments (the output values from a Plant-Canopy-Analyzer, LAI2000) and the Brix or the each chromaticity value of L*a*b was high in order of DIFNィイD2360,0-74ィエD2 of the 3-year-old branch bearing the fruits) the mean DIFNィイD2360,0-74ィエD2 of neighbor 3-year-old branch DIFNィイD2360,0-74ィエD2 of neighbor 4-year-old branch. But, the significant and high correlations were found only to DIFNィイD2360,0-74ィエD2 of the 3-year-old branch bearing the fruits of the mean DIFNィイD2360,0-74ィエD2.

研究了樱桃、梨、苹果和日本柿果实快速生长期ィイD113ィエD1C-光合作用产物在ィイD113ィエD1COィイD22ィエD2暴露后44~72小时内在成熟树2年生枝条间的运转情况。此外，在不同树龄的枝条上进行环志处理，并与对照比较果实和茎的生长情况。研究了苹果‘富士’成熟树10个3年生枝条上果实的生长和品质与光环境的关系。总ィイD113ィエD1C从ィイD113ィエD1COィイD22ィエD2向3年生枝条内其他枝条转移的比例在樱桃中为2.5~27%，在梨中为5~29%，在苹果中为0.5~16%，在日本柿中为0~31%。这些比例高于用ィイD113ィエD1COィイD22ィエD2.2喂养3年或4年生树枝的试验。大多数环剥处理的果实和枝条的最终直径与对照没有太大差异。而且，不同树种间处理枝条年龄差异的影响并不明显。4种光环境(LAI2000植物冠层分析仪的输出值)与L*a*b的锤度或各色度值之间的相关性依次为：3年生结果枝的ィイD2360，0-74ィエD2；邻生4年生枝的平均ィイD2360，0-74ィエD2。但只有3年生的结果枝条的ィイD2360，0-74ィエD2与D干扰素ィイD2360，0-74ィエD2呈显著正相关。
