Abstract

. Fuadi, M. and Y. Hilman. 2008. The Effect of Benzyl Adenine Concentration on Postharvest Quality of Dracaena sanderiana and Codiaeum variegatum. This study was carried out with the main objective of looking at the effects of benzyl adenine (BA) on the growth and quality retention of Dracaena sanderiana and Codiaeum variegatum during simulation of subsequent shipping conditions (in the dark chamber). Concentrations of BA applied were 0 (control), 75, 150, 225, and 300 mg/l. The results showed that the growth and plant quality of D. sanderiana and C. variegatum in terms of photosynthesis rate, stomatal conductance, chlorophyll content, plant height, and plant grade were significantly (p<0.05) affected by BA. The highest photosynthesis rate (6.74 μmol/m2/sec.) and chlorophyll content were found on D. sanderiana sprayed with 300 mg/l BA, while C. variegatum gave the highest photosyntesis rate (5.40 μmol/m2/sec.) at application of 150 mg/l BA. As expected, photosynthesis rate increased with higher chlorophyll content. The photosynthesis rate for both treatments were double compared to the other treatments. Stomatal conductance, leaf fresh weight, and plant grade were also significantly (p<0.05) affected with different concentrations of BA. Similar to the photosynthesis and chlorophyll content of D. sanderiana, plants sprayed with 300 mg/l BA showed a better growth response, while C. variegatum needs lower concentrations (150 mg/l BA). In order to obtain a good plant grade in term of leaf freshness, D. sanderiana and C. variegatum required BA concentration of 300 mg/l (4.50 = excellent quality) and 150 mg/l (4.17 = excellent quality) respectively
