摘要

本試驗目的為研究除雄處理及GA3與Auxin類生長調節劑對麻芝茄果實生長及種子量之影響。‘麻芝茄’以除雄、10 mg l^(-1) 2,4-D處理之果重及無子果實率分別為90.9 g、76.2%最佳，未除雄之果重分別以10 mg l^(-1) 2,4-D、100 mg l^(-1) NAA處理之174.5及176.8 g最佳。Auxin類之生長調節劑中，‘麻芝茄’經由處理10 mg l^(-1) 2,4-D其種子數最少而無子果實率表現最佳。

The study examined the effect of the emasculation and growth regulators (including GAs and auxins) on the fruit growth and number of seed of eggplant. The results showed that the best seedless fruit production was obtained from emasculated flowers upon treatment with 10 mg l^(-1) 2,4-D, resulting in a fruit weight of 90.9 g and a seedless rate of 76.2% for 'Matsu' eggplant; while fruits obtained from unemasculated flowers exhibited the best production rate upon treatment with 10 mg l^(-1) 2,4-D and 100 mg l^(-1) NAA, resulting in a fruit weight of 174.5 and 176.8 g, respectively. For GA3, a concentration of 200 mg l^(-1) resulted in the best seedless rates in all cultivars. The lowest total seed number and the highest percentage of seedless fruits for 'Matsu' eggplant were treated by 2,4-D.
