| 摘 要： | 【目的】研究温州蜜柑的树相指标，为柑橘优质栽培提供科学依据。【方法】以21年生国庆一号温州蜜柑为材料，研究温州蜜柑结果母枝、结果枝类型与坐果率、果实横径的关系。【结果】结果母枝长度为0.13～46.50 cm、粗度为0.12～0.92 cm，随着结果母枝增长和增粗，单位母枝上有叶结果枝数增多，有叶结果枝坐果率高于无叶结果枝坐果率；结果母枝粗度≤0.20 cm时，其上有叶结果枝坐果率和无叶结果枝坐果率均最高，结果母枝长度≤10.0 cm时，有叶结果枝坐果率最高，但结果母枝粗度、长度与有叶、无叶结果枝的坐果率相关性均不显著；叶数为1～3片的有叶结果枝结果数量最多，占结果总数的87.6%；结果母枝粗度、长度分别与其果实横径呈极显著和显著的正相关，但果实横径与结果枝叶数相关性不显著；有叶结果枝比无叶结果枝的果实普遍较大。【结论】温州蜜柑以粗度和长度较小的结果母枝为主，但粗壮的结果母枝能抽出较多的有叶结果枝，有利于提高坐果率、增大果实横径，生产上要注意粗壮结果母枝的培养。

| Abstract: | [Objective]Tree morphological indices were studied in order to provide scientific references for good-quality citrus fruits cultivation.[Method]Relationships among mother fruit-bearing branch,type of fruit-bearing branch,fruit-setting rate and fruit diameter were investigated in 21-year-old Satsuma mandarin Guoqing 1 trees.[Result]The length and thickness of mother fruit-bearing branch ranged from 0.13-46.50 and 0.10-0.92 cm,respectively.Longer and thicker mother branches were found to have more fruit-bearing branches with leaves.The fruit-setting rate was higher in fruit-bearing branch with leaves compared to those without leaves.The fruit-setting rates of both the fruit-bearing branch with and without leaves were the highest when the diameter of mother fruit-bearing branch was less than or equal to 0.20 cm.But it was the highest in fruit-bearing branch with leaves,when the length of mother fruit-bearing branch was less than or equal to 10.0 cm.No significant correlations were observed between the diameter and length of mother fruit-bearing branch and fruit-setting rate of fruit-bearing branch with or without leaves.The fruit number on the fruit-bearing branch with 1 to 3 leaves was the highest,accounting for 87.6%.Diameter and length of mother fruit-bearing branch was positively correlated with fruit diameter,nevertheless fruit diameter had no correlations with the number of leaves in fruit-bearing branch.Lastly,fruits of the fruit-bearing branch with leaves were generally bigger than those without leaves.[Conclusion]Trees of Satsuma mandarin have large number of relatively small and short mother fruit-bearing branches.However,thicker and stronger mother fruit-bearing branch can produce more fruit-bearing branches with leaves leading to higher fruit-setting rate and bigger fruits.Hence,maintaining thicker and stronger mother fruit-bearing branch should be taken into account in its production. |
