Abstract
The effect of fungicide and plant growth hormones on germination ofteak (Tectonagrandis) seed was studied in a four-factorial experiment (2 X 4 x 7 x 4). The fungicide ceresan at two levels 0 and 0.4 four growth hormones I-naphthyl acetic acid (NAA) indole acetic acid (IAA) gibberellic acid (GA ) and kinetin with seven concentrations (0 5 10 15 20 25 and 30 ppm) and four seed soaking periods 0 3 5 and 7 hours) were applied to mechanically extracted seeds from teak fruits before sowing. Presowing seed treatments significantly influenced germination of seeds after seven days. Under fungicide application maximum seed germination was recorded in NAA at 25 ppm with 3 hours soaking followed by G-\ at 15 ppm 5 hours and 1M 5 ppm 5 hours. Longer soaking time (7 hours) did not favour seed germination. Relative cost/benefit ratio of hormone application and economics of seed treatment with fungicide and honnones showed that NAA and IAA 5 ppm with fungicide were the best treatment recovering the cost ofseeds by a factor of9.83 times over the control due to enhancement ofseed germination. This seed treatment is found suitable for raising teak seedlings in root trainer in modern forest nursery.
