摘要

苦瓜、絲瓜和南瓜同屬葫蘆科作物，親和性強，嫁接活率高。本研究中二品種苦瓜接穗分別嫁接絲瓜或南瓜砧木，接穗主蔓或子蔓因嫁接砧木而縮短，絲瓜為砧木顯著增加木質液量及南瓜為砧木使苦瓜嫁接處為砧負現象，嫁接對‘粉青’苦瓜植株鮮乾重顯著減少，‘碧華’苦瓜植株鮮乾重則無顯著影響，對苦瓜葉片光合作用及水分潛勢無顯著影響。

Bitter gourd, sponge gourd and pumpkin are Cucurbits, which had strong affinity and high living grafting percentage. In this study, two varieties of bitter gourd scions grafted onto a luffa or squash through cleft grafting. The shoots of scions were shortened by grafted. The content of xylem sap from the luffa rootstock showed great compared to that from the pumpkin. The diameter ratio of scion stem / rootstock stem of the pumpkin rootstock was significantly decreased. The plant fresh weight and dry weight of 'Fen Ching' bitter gourd were significantly decreased after grafting, and of 'Luxuriance' bitter gourds were not significantly affected. The water potential and photosynthesis of the leaf were not significantly different between the grafted and un-grafted bitter melon.
