常见葫芦科作物砧木嫁接甜瓜其品质差异分析

目的]分析常见葫芦科作物砧木嫁接甜瓜(Cucumis melo L.)后甜瓜的生长发育及果实品质。方法]以东甜02自根苗作为对照,进行以南瓜(Cucurbita moschata)、大葫芦Lagenaria siceraria(Molina)Standl.var.gourda Ser.]、瓠子Lagenaria siceraria(Molina)Standl.var.clavata Ser.]、丝瓜(Luffa cylindrica)、节瓜Benincasa hispida(Thunb.)Cogn.var.chieh-qua How]为砧木、东甜02为接穗的嫁接栽培比较试验,研究不同砧穗组合的嫁接成活率、植株生长速率和果实性状。结果]以节瓜、丝瓜为砧木,不利于东甜02果实优良性状的表现,而以瓠子、南瓜为砧木,对东甜02有积极的影响,而以大葫芦为砧木,则利弊参半。结论]该研究可为甜瓜嫁接栽培的发展提供理论依据。

Effects of Different Common Cucurbitaceae Grafting Rootstock on Growth, Development and Quality of Melon(Cucumis melo L.)

Objective ] The aim was to analyze growth, development and quality of melon after grafting using common Cueurbitaceae grafting rootstock. Method] The self-root seedling of Dongtian 02 was used as control. And pumpkin （Cucurbita moschata）, big gourd Lagenaria siceraria （Molina） Standl. var. gourda Ser. ], ground melon Lagenaria siceraria （Molina） Standl. var. clavata Set. ], zucchini（Luffa cylin- drica）, and luffa Benincasa hispida （Thunb.） Cogn. vat. chieh-qua How] were used for grafting to melon Dongtian 02. The experiment studied different rootstocks on the grafting survival rate, growth rate and fruit characteristics. Result ] The results indicated that using luffa and zucchini as grafting rootstock were not suitable for the improvement of melon quality whereas gourd melon and pumpkin had the positive in- fluence on performance. As grafting rootstock, big gourd has advantages and disadvantages. Conclnsion] The study provides a theoretical ba- sis for melon grafting cultivation development.
