The Minolta SPAD 502 meter is a hand-held light meter used to measure the relative greenness of leaves in a rapid manner. (SPAD is an acronym for Soil Plant Analysis Development.) SPAD 502 determines the relative amount of chlorophyll present by measuring the transmittance of the leaf in two wave bands (600 valuable tool for forest managers and researchers. evaluated at pot cultivation conditions. This study was performed in repeation with 12 treatments. The objective of this study was to evaluate the ability of a estimate chlorophyll (CHL) of foliar application with benzyladenine (BA) at 0, 100, 200 chlorophyll contents. Effect of Gibberellic Acid and the interaction significant (p<0.01) also effect of Benzyladenine was significant (p<0.01) on chlorophyll content for 60 and 180 day after spray. concentrations of Plant Growth Regulators and control. According to variance analysis, significant differences were observed among 400 mg.L-1 BA + 200 mg.L-1 GA3 and 400 mg.L spray, with 29.6, 66.75 and 54.82, respectively.
