    The objective of the present work was to study the effect of Triacontanol and Agrostemmin on rice seeds by evalluating germination, coleoptile and seedling root growing, under laboratory conditions. The Petri dishes received 10 ml of solution (ether and benzene) for Triacontanol treatments and distilled water for the Agrostemmin treatments. Results showed that the treatments does not present significant effects in relation to germination percent but a statistically significant effect with respect to seedling root growing was observed.O presente trabalho teve como objetivo estudar o efeito de Triacontanol e Agrostemin em sementes de arroz, atravĆ©s da avaliaĆ§Ć£o da germinaĆ§Ć£o, do crescimento de coleĆ³ptiles e raĆ­zes das plĆ¢ntulas, em condiƧƵes de laboratĆ³rio. As placas de Petri receberam 10 ml de soluĆ§Ć£o (Ć©ter e benzeno) correspondente aos tratamentos com Triacontanol, enquanto as dosagens de Agrostemin foram aplicadas em soluĆ§Ć£o de Ć”gua destilada. Verificou-se que nenhum dos tratamentos mostraram efeitos significativos sobre a porcentagem de germinaĆ§Ć£o, mas provocaram um crescimento diferencial estatisticamente significativo em relaĆ§Ć£o as radĆ­culas
