種苗大小對瓜類機械嫁接苗成活之影響

將瓜類蔬菜作物於不同育苗日數下培育各種大小種苗，以日本GR800-B瓜類半自動嫁接機，分別將三種主要作物之接穗苗嫁接於三種同科作物之根砧苗上，扦插於72格穴盤中，進行不同規格接穗與根砧組合試驗，調查其成活率，以篩選出適用於嫁接機操作且能互相配搭之穗砧規格。試驗結果顯示胡瓜接穗苗以8-12天、苦瓜以7-10天、西瓜以7-9天、南瓜根砧苗以7-10天、絲瓜以7-11天、扁蒲以7-10天苗齡之規格較適合嫁接機進行作業。瓜類苗齡6天內因子葉未完全展開，莖徑細小無法進行機械嫁接。南瓜、扁蒲根砧苗齡達11天以上時，莖部漸有中空現象產生，使嫁接成活率下降。

The purpose of this study was to assess the suitable size and nursery days of cucurbits seedling for grafting by GR800-B robot. Plug seedlings of cucumber, bitter gourd, and watermelon as scion as well as squash, luffa, and bottle gourd as stock were grown in different days. There was various combination according to the different grown days of seedling while grafting. The survival ratio of grafted plants was investigated. The results showed that appropriate scion size of cucumber seedling was 8-12 days, of bitter gourd seedling was 7-10 days, and of watermelon seedling was 7-9 days. The appropriate stock size of squash seedling was 7-10 days, of luffa seedling was 7-11 days, and of bottle gourd seedling was 7-10 days. The six days old seedlings were not suitable for grafting by robot because the cotyledons did not completely expand and the diameter of stem was very small. The stem of squash and bottle gourd seedlings, over 11 days, became hollow which would reduce the survival ratio of grafted seedlings.
