Abstract

Field trials with Ficus benjamina L.were conducted at the experimental farm of Faculty of Agriculture, University Azad Jiroft in 2012 growth seasons. The aim of this work is to study the effect of foliar application with gibberellic acid (GA3) and benzyladenine (BA) at 0, 100 and 200 mg.L-1 on the vegetative growth and Photosynthetic pigments of Ficus benjamina plants. The obtained results show, number leaves  was in a plant in applications of 200 mg l-1 GA3 +100 mg l-1 BA, 200 mg l-1 GA3+200 mg l-1 of  BA  and respectively, with average of  133.25 and 130.5  that  they did not  show  a meaniful diference, statically. maximum Length of lateral shoots and Number of shoot/plant was obtained in applications of 200 mg l-1 GA3+200 mg l-1 BA with average of  30.74 cm and 21.75. The  results  show, by increasing concentration of  regulators of  growth, plant height, stem diameter, number of leaves and shoot/plant, leaf area, Length of lateral shoots, SPAD and Photosynthetic pigments is increased. highest value of chlorophyll  of  a, b was total and sum pigments in level of 200 mg l-1 GA3,100 mg l-1 GA3+200 mg l-1 GA3, 100 mg l-1 GA3+200 mg l-1 GA3 and100 mg l-1 GA3+200 mg l-1 GA3 with average of 10.56, 5.81, 16.39 and 19.59 g l-1.
