| Abstract | ||
| The effect of magnesium and benzyladenine (BA) on growth and flowering of Lisianthus (Eustoma rusellianum) cv. Super magic was investigated. Three levels of magnesium (Mg EDTA) 0, 0.5 and 1 g/l, and four concentrations of BA 0, 10, 20 and 40 mg/l were tested. The results could be summarized as follows: 1- Magnesium at 1 g/l increased plant height (62.01 cm.), leaves content of chlorophyll 573.1 mg/m2, leaf area (1201.28 cm2), dry weight of vegetative growth/plant (20.97 g) and leaves content of Mg (0.83%). While the highest level of BA decreased plant height. Benzyladenine treatments elevated number of flowering branches, number of leaves and chlorophyll content (5.90 branch/plant, 88.16 leaves, 565.3 mg/m2) respectively. Leave contents of N was maximum (1.14%) at 20 mg/l of BA. Highest levels of P in leaves (0.40%) was admitted at 40 mg/l. 2- The interactions between magnesium and BA was significantly increased number of branches/plant (6.18) at BA3×Mg1 treatment, number of leaves (93.08) at BA3×Mg2 treatment, leave area (1361.40) cm2 at BA0×Mg3 treatment. % of chlorophyll 593.5 mg/m2 at BA1×Mg2 treatment and dry weight of vegetative growth 21.45 g at BA3×Mg1 treatment. Moreover, the interaction was effective on leave content from N, P, K and Mg as well. 3- Higher levels of P increased length and diameter of flowering stem (43.90 and 4.87 mm.) respectively, vase life (1279) days was elevated as well. While BA decreased length and diameter of flowering stem. diameter of flowers, However, vase life, number of inflorescence and number of florets were increased. 4- The interactions between Mg and BA significantly increased some of flowering parameters. Fastened the flowering (198.33) days, dry weight of flowers was elevated (0.38 g.) at BA2×Mg1 treatment, vase life (12.83) days at BA2×Mg2 treatment was prolonged. Moreover, number of inflorescence/plant and number of florets were increased (14.15 inflo/plant at BA3×Mg2 treatment, 38.63 floret at BA3×Mg0 treatment) respectively. | ||
