토마토 대목의 수경재배 적응성 및 수경재배 시 실생묘와 접목묘의 생육 비교

Grafting is a general tool to improve environmental tolerance and productivity by using the characteristics of rootstocks. This study was conducted to examine the hydroponic cultivation adaptability of rootstock varieties and to verify the effect of grafting in hydroponic cultivation in tomato. In order to search for rootstocks suitable for hydroponic cultivation, the growth and nutrient solution uptake of 3 cultivars and 8 rootstock varieties were investigated. In addition, in order to verify the grafting effect, the growth and nutrient absorption characteristics for 3 cultivars (‘Minichal’, ‘Superdoterang’ and ‘Daphnis’) of seedlings and grafted onto ‘B blocking’ and ‘Maxifort’ rootstock respectively. There was a difference in the number of leaves and leaf area for each tomato rootstock and cultivar. Compared to the cultivars, ‘Maxifort’ and ‘Butimmok’ had more nutrient solution absorption, and ‘Doctor Q’, ‘Allround’, ‘B blocking’, and ‘Fighting’ had less nutrient solution absorption. Compared to seedling, Grafted tomato onto ‘B blocking’ absorbed less nutrient solution, while Grafted tomato onto ‘Maxifort’ had more. There was no difference between seedling and grafting onto ‘Maxifort’ in plant length, stem diameter and number of leaves. However, the grafting had remarkably large leaf area, fresh weight of shoot and root and volume of root. ‘Daphnis’ and ‘Minichal’ increased the growth in grafting, and ‘Superdoterang’ showed relatively little grafting effect.
