Abstract

The effect of Gibberellic Acid and Benzyladenineon Ficus benjamina, Schefflera arboricola and Dizigotheeca elegantissima plants was evaluated at pot cultivation conditions. This study was performed in three factorial test based on completely randomized design and 4 repeats with 9 treatments. The aim of this work is to study the effect of foliar application with gibberellic acid (GA3) at 0, 100 and 200 mg.L-1and and benzyladenine (BA) at 0, 100 and 200 mg.L-1 levels. The results showed, The highest rate of Plant Height with 76.5, 52.5 and 36.25 cm belonged to 200 mg l-1 GA3+200 mg l-1 BA, respectively between three indoor plants Ficus benjamina, Schefflera arboricola and Dizigotheeca elegantissima. The lowest rate of Plant Height with 57.5, 31 and 27 cm belonged to control treatment, respectively in three indoor plants Ficus benjamina, Schefflera arboricola and Dizigotheeca elegantissima. According to results, the highest rate of Plant Height in three indoor plants Ficus benjamina, Schefflera arboricola and Dizigotheeca elegantissima was related to Ficus benjamina plant that had higher Plant Height compared to two other plants. The highest rate of Number of leaves/plant with 133.25, 22.75 and 41.5 belonged to 200 mg l-1 GA3+100 mg l-1 BA and 200 mg l-1 GA3+200 mg l-1 BA for plants Ficus benjamina, Schefflera arboricola and Dizigotheeca elegantissima. The highest value of Ficus benjamina, Schefflera arboricola and Dizigotheeca elegantissima of sum pigments in level of 100 mg l-1 GA3+200 mg l-1 BA and 200 mg l-1 GA3+200 mg l-1 BA with average of 19.59, 21.65 and 21.88 g.ml-1.
