摘要

將不同嫁接時間與嫁接狀況（處理良好、劣質）之番茄嫁接苗與番茄實生苗進行各項生理代謝物分析，以瞭解嫁接處理對番茄苗生理之影響。結果顯示嫁接處理會影響番茄植株生理代謝之反應。尤其是嫁接處理後8天內，在番茄葉綠素、蛋白質、脯氨酸、可溶性碳水化合物及丙二醛含量上都有明顯的變化。其中脯氨酸與可溶性碳水化合物含量不僅能明顯區別嫁接與非嫁接處理者，對於嫁接良好與否也極容易區別，顯示應可作爲番茄嫁接處理之生理指標，以爲番茄嫁接苗自動化作業相關研究與提升種苗品質之參考。

This study investigated the physiological metabolites content of tomato seedlings by different grafting treatment. The result shows that the metabolites of tomato seedlings were affected by grafting treatment. The content of chlorophyll, protein, proline, total soluble carbohydrate, and malondialdehyde in leaves were analyzed for 8days after grafting treatment, and they changed evidently. The contents of proline and total soluble carbohydrate content were significantly different not only between grafted and self rooted tomato seedlings, but also between fully matched grafts and half matched grafts, therefore, the proline and total soluble carbohydrate content of tomato seedling would be good physiological indicators for grafting treatment, and can be the reference for studies concerning tomato grafting and enhancing the qualities of the seedlings.
