摘要

本試驗研究茄子砧木嫁接番茄對嫁接植株生長動態及乾物質生產之影響，結果顯示87年秋作‘小丹茄’等四個茄子砧木嫁接組合與‘農友301’未嫁接植株之株高在嫁接後0~60天均無顯著差異，接穗與砧木莖徑比值以'KSA22'砧為最大。四種茄子砧木嫁接組合植株之葉面積均高於對照未嫁接者，地上部乾物重、根乾物重及總乾物重增加之相對速率，四個茄子砧木嫁接植株與未嫁接植株在嫁接後60天時差異顯著，表現出嫁接組合優於未嫁接植株之趨勢。88年春作嫁接60天後，株高、葉面積、嫁接部位接穗與砧木莖徑比值、總乾物重、地上部乾物重、根乾物重及總乾物重相對生長速率皆以‘小丹茄’及'VF(F1)'砧之組合表現比未嫁接者優異。而88年夏作以‘小丹茄’等四個茄子砧木與大果番茄‘台中亞蔬4號’嫁接組合中，除了總乾物重之相對速率以‘赤茄’砧表現高於其他組合，其他生長動態及乾物質生產結果以‘小丹茄’及'VF(F1)'砧表現較未嫁接者優異。這些結果獲致要成為優良砧木，必須於不同生育季節，在穗砧癒合後均能快速生長者。

The plant growth of 'Known-You 301' tomato grafted on four eggplant varieties rootstock was studied in autumn, 1998. The leaf area, shoot dry weight, root dry weight, and relative growth rate of total dry weight of grafted plants were larger than those of un-grafted tomato after grafting 60 days. The height of grafted plants was not significantly different compared to control plant. When the rootstock was 'KSA22' eggplant, the ratio of scion stem to stock stem was the largest among four root stocks. The plant growth dynamic was increased when plants grafted on 'Hsio-Tan' and VF(F1) rootstock in spring, 1999. In summer crop, 1999, 'Asian No4' tomato was grafted on four eggplant varieties rootstock. Tomato grafted 'red eggplant' rootstock increased the relative growth rate of total dry weight. The plant growth dynamic, shoot dry matter and root dry matter were increased when plants grafted on 'Hsio-Tan' and VF(F1) rootstock. The results could be concluded that the rapid growth of the grafted plant after scion and rootstock fused completely in different seasons will be an important evaluation index of good rootstock.
