investigating of the effects of calcium concentration under hydroponic conditions on quantitative and qualitative growth of lilium ‘tresor

the asiatic hybrid lily, a bulbous ornamental plant, has a special position in the horticulture as cut flower. to overcome some problems in nutrition of bulb flowers, the use of hydroponic system and nutrient solution is important in the cultivation of these flowers. the asiatic hybrid lilium bulbs “tresor” cultivar, used for the current research were planted under 3 different calcium levels including 2, 4 and 6 mm as randomised completely designed with five replications. comparing the mean values of the data showed that 6 mm calcium produced maximum height of the plant, stem diameter, procreative height, number of buds, flower diameter and longevity of cut flowers
