Response of Application Gibberellic acid (GA3) and Benzyladenine (BA) to Dizigotheeca elegantissima Plants

Field trials with Dizigotheeca elegantissima were conducted at the experimental farm of Faculty of Agriculture, Azad University Jiroft in growth seasons of 2012 year. The aim of this work was to study the effect of foliar application of gibberellic acid [GA3] and benzyladenine [BA] at 0, 50, 100 and 150mgL-1 on the vegetative growth and Photosynthetic pigments of D. elegantissima plants. Most of the vegetative growth characteristices like plant heights, number of leaves/plant, chlorophylle index and Photosynthetic pigments were significantly affected by application of the two factors which were used inthis study. All foliar applications of BA and GA3 separately promoted all the afore mentioned charactersin this study, as well as Photosynthetic pigments i.e. Chl. [a and b], totol and sum pigments compared with control plants. The highest recorded data were obtained in plants treated with 200 mgL-1 GA3+200 mgL-1 BA for plant height, number of leaves/plant and chlorophylle index, except with 200 mgL-1 GA3+100 mgL-1 BA which gave the highest leaf area.
