These grafting seeding “Torobambica” rootstock “huk Yang”were tested to investigate the growth, yield, and quality of eggplants which can be influenced by the bumblebee pollination and plant growth regulators. The results were as follows: According to the treatment of bumblebee pollination and plant growth regulators, the yield of eggplant was good at bumblebee pollination with tomatotone flower spray at blooming time, and was good at foliage spray on the treatment of tomatotone and GA3, and was good at flower clusters spray on the treatment of tomatotone. According to the treatment of bumblebee pollination and plant growth regulators, the ratio of marketable fruit was good at pollination bumblebee with tomatotone spray on the day they flowered, was good at foliage spray on the treatment of tomatotone and GA3, and was good at flower clusters spray on the treatment of tomatotone. On the mineral element contents of eggplant stems, the contents of total nitrogen were good at tomatotone flower spray at blooming time, the ones of phosphorus, potassium, and magnesium were good at tomatotone foliage spray the rate of three days, the ones of calcium were good at tomatotone flower spray in two or three days before flowering, and ones of ash were good at tomatotone flower spray at blooming time, foliage spray the rate of three days. On the mineral element contents of eggplant fruits, the contents of total nitrogen were good at tomatotone and GA3 foliage spray the rate of six days, the ones of phosphorus were good at tomatotone foliage spray the rate of three days, the ones of potassium, ash were good at tomatotone and GA3 flower spray at blooming time, and the ones of calcium, magnesium were good at tomatotone an GA3 flower spray in two or three days before flowering.
