Effect of four nutrient solutions on morphological, flowering and growth indexes of Begonia cucullata ‘Super Olympia Series’was comparied, and on this basis, the nutrient solution formulation suitable for soilless cultivation of the cultivar was selected. The results show that the four nutrient solutions tested have promotive effects on leaf number, height, crown diameter, inflorescence number, floret number, male flower diameter, fresh and dry weights of above-and under-ground parts, length of root system and maximum leaf area at different degrees. In which, T7 nutrient solution (i. e.Japanese YuanShi nutrient solution) has the significantly promotive effects on morphological, flowering and growth indexesof the cultivar. Therefore, it is suggested that T7 nutrient solution may be used for soilless cultivation of the cultivar.
