EFFECT OF CALCIUM AND BORON CONCENTRATIONS ON SOME CHARACTERISTICS IN CUT ROSE 'EASY LOVER' CULTIVAR
One of the most important factors in improving the yield and quality of cut flowers is fertilization balanced. This study was conducted to determine the effects of concentrations of boron and calcium on root growth and mineral content of Easy Lover rose (Rosa hybrid L.) grown in soilless culture. The experiment was arranged in a factorial based on a randomized complete block design with four replications. Treatments were consisted three levels of B (25, 50, and 75 µM) and three levels of Ca (2.5, 5, and 7.5 mM). Results showed that increasing B and Ca concentration in nutrient solution improved root development. Increasing B and Ca increased length, diameter, number and area of roots. Increased Ca content in the leave and petal was observed as a result of increasing Ca and B concentration in the culture medium. High Ca concentration in the nutrient solution antagonized the B content in leaf and petal.
