| Abstract | ||
| Two field experiments studies were conducted at the Floriculture Nursery of the Horticulture Department, Faculty of Agriculture at Moshtohor, Benha University, during 2016 to 2017 seasons to study the effect of spraying amino acid at the rate of 0.0, 1.0, 2.0 and 3 g/l and salicylic acid at the rates of 0, 50, 100 and 200 ppm as well as their interaction on vegetative, flowering growth and chemical composition of geranium plants. Obtained results showed that, the tallest plants, the highest number of branches / plant, the greatest show value, the heaviest fresh and dry weights of leaves/ plant and the widest plant were recorded by 200 ppm SA-sprayed plants supplemented with amino acid at 3 g/ l in the two seasons. Moreover, sprayed geranium plants with salicylic acid at 200 ppm and supplemented with amino acid at 3 g / l is being the most effective one for producing the highest number of flowers / plant, the heaviest fresh and dry weights of flowers / plant (g), the longest duration of flower on plant (days) and flowering duration on plant (days) in the two seasons. Furthermore, he greatest leaf nitrogen, phosphorus, potassium, total carbohydrates % were recorded by the plants treated with amino acid at the high level and sprayed with salicylic acid at 200 ppm, in the two seasons of this experiment. Conclusively, sprayed geranium plants with salicylic acid at 200 ppm and supplemented with amino acid at 3 g / l produced the best growth, chemical constituents and quality of this plant. | ||
