In this study, we investigated the changes of growth characteristics, mineral and chlorophyll content of young leafy vegetable of Chinese toon grown under greenhouse and open fields. Results showed that growth of young leafy vegetable of Chinese toon was somewhat accelerated in greenhouse compared to the open field. In case of apical bud growth, several parameters such as plant height, number of branch, fresh weight and chlorophyll content showed similar tendency in both greenhouse and open field. In the changes of minerals, N content in apical buds recorded significant increase to 3.1 times compared to that of later buds. Its content was 1.2 times higher in greenhouse than that of open field. Mineral contents including P, Ca, Mg and Fe were significantly increased in greenhouse. Highest ascorbic acid content was observed in lateral buds grown in greenhouse and then it was followed such as lateral bud in open field, apical bud in open field, and apical bud in greenhouse, in turn. These results indicate that greenhouse culture could be applicable to new culture in order to produce young leafy vegetable of Chinese toon with high quality.
