Abstracts

The effects of growth regularots on soybean plant (Glycine max) under greenhouse conditions were studied. Before flower ing, Agrostemmin (1 g/10 ml/3 1), gibberellic acid (GA) 100 ppm, and (2-chloroethyl) trimethylammonium chloride (CCC) 2,000 ppm were applied. At the flower anthesis, 2,3,5 - triio dobenzoic acid (TIBA) 20 ppm was applied. Other two applications with TIBA, with intervals of four days, were realized. Treatment with GA increased plant height while CCC presented a tendency to reduce it. Numbers of leaves, internods, and stems were not affected by the growth regulators.

Determinou-se em condições de casa de vegetação o efeito de fitoreguladores no desenvolvimento da soja (Glycine max cv. Davis). Aplicou-se através de pulverização o ácido 2,3,5-triiodobenzoico (T1BA) na concentração de 20 ppm, três vezes, com quatro dias de intervalo a partir do início da florescência. Antes da florescência aplicou - se Agrostemin (1 g/10 ml/3 l), ácido giberélico (GA) 100 ppm e cloreto (2-cloroeti1) trimetilamônio (CCC) 2.000 ppm, além do controle. Plantas de soja tratadas com GA apresentaram maior altura em relação ao controle, sendo que o CCC tendeu a reduzir a altura das plantas. Os fitoreguladores não afetaram o número de folhas, meritalos e hastes da soja 'Davis'.

RESUMO

Determinou-se em condições de casa de vegetação o efeito de fitoreguladores no desenvolvimento da soja (Glycine max cv. Davis). Aplicou-se através de pulverização o ácido 2,3,5-triiodobenzoico (T1BA) na concentração de 20 ppm, três vezes, com quatro dias de intervalo a partir do início da florescência. Antes da florescência aplicou - se Agrostemin (1 g/10 ml/3 l), ácido giberélico (GA) 100 ppm e cloreto (2-cloroeti1) trimetilamônio (CCC) 2.000 ppm, além do controle. Plantas de soja tratadas com GA apresentaram maior altura em relação ao controle, sendo que o CCC tendeu a reduzir a altura das plantas. Os fitoreguladores não afetaram o número de folhas, meritalos e hastes da soja 'Davis'.
