Abstract

False aralia (Dizygothecaelegantissima) also known as spider aralia or threadleaf aralia, is grown for its attractive foliage. The long, narrow, dark green leaves with saw-tooth edges are coppery colored at first, but as they mature they turn dark green, appearing almost black on some plants. Field trials with False aralia (Dizigotheecaelegantissima) were conducted at the experimental greenhouse of Faculty of Agriculture, Azad University Jiroft in growth seasons of 2013. The aim of this work was to study the effect of foliar application of gibberellic acid (GA3) and benzyladenine (BA) both at 0, 100 and 200mgL-1 on the growth and photosynthetic pigments of Dizygothecaelegantissima plant. Effect of GA3and interaction significant (p<0.01) also effect BA on leaf area was non significant. Results showed that, 200 mg L-1 GA3+ 200 mg L-1 BA increased leaf area of False aralia as 43.87% compared to control treatment. 200 mg L-1 GA3 + 200 mg L-1 BA increased chlorophyll index, plant height and leaf area of False aralia as 61.62, 24.48 and 43.87% compared to control treatment. Also 200 mg L-1 BA cause increased chl. (b), total chl. a+b and sum pigments of False aralia as 15.65, 38.03 and 36.91% compared to control treatment.
