Abstract : The study on effects of brassin-like substance on some physical and biochemical changes of mango fruit cv. Mahajanaka. The experiment was designed in randomized complete block design (RCBD) with 5 treatments and 4 replication. Commercial, brassin-like substance (active ingredient 0.4%) at the application rate of 0.025, 0.125, 0.250 and 0.370 ppm by water as the control, were sprayed on mango trees at 30 days after full bloom. It revealed that all brassin-like substance treatments caused heavier fresh weight and bigger fruit and endocarp than those of the control. Among all brassin-like substance application, 0.025 ppm was the most effective rate in increasing the fruit size and fresh weight. If could be inferred that brassin-like substance the mango fruit cv. Mahajanaka fruit size. However, TSS, TA and TSS:TA of the fruit did not significant differences among all treatments.
