摘要

本試驗目的在於探討不同留蔓及留果數對設施東方甜瓜品種間生育之影響。由試驗結果顯示，不同甜瓜品種間（‘銀輝’及‘嘉玉’）在葉片性狀（葉長、葉寬及葉柄長及莖粗），或在果實性狀方面如果長、果徑、單果重及總可溶性固形物等處理間，並無顯著性差異。不同留蔓數及留果數各處理間，在葉片性狀如葉長、葉寬、莖粗及節間長無顯著性差異；在果實性狀方面，整體表現以單蔓1果處理顯著優於其他處理。對甜瓜葉片元素方面，分析結果顯示品種間、不同留蔓數及留果數處理間，對葉片元素在氮、磷、鉀、鈣及鎂等無機養分含量，各處理間均未達顯著性差異。微量元素在不同留蔓數及留果數處理間，除了葉片鐵含量未達顯著性差異外，其餘銅、錳及鋅等無機養分含量處理間，均已達顯著性差異。基於果實是甜瓜栽培的標的器官，建議東方甜瓜仍以單蔓1果為宜。

This study aimed to understand the effects of branch and fruit number on the growth of oriental melon cultivars under greenhouse. The results showed that the leaf and fruit characteristics (fruit length, fruit diameter, single fruit weight and total soluble solid content) was not significantly different of oriental melon cultivars (Silver Light and Jill). There were no significant differences in leaf characteristics (leaf length, leaf width, stem thickness, and internode length) between the branch and fruit numbers, and the overall fruit characteristics was significantly better in the 1 branch and 1 fruit treatment(A), than tha others. For melon leaf elements, the analysis results showed that the content of inorganic nutrients in the leaves, such as N, P, K, Ca and Mg, among the varieties and between different treatments of branch and fruit number was not significantly different. On minor mineral elements in leaves, Fe content was not significant different among the treatments, but Cu, Mn and Zn was reached a significantly different. Because the fruit is the target organ for melon cultivation, it is recommended that the method of 1 branch and 1fruit treatment should be adopted.
