| Abstract: | The objective of this experiment was to study the effects of different concentrations of the plant growth regulators prohexadione-calcium (ProCa) on the growth control of tomato seedlings. The experiment was conducted in the forest seedling nursery of the Faculty of Agronomic Sciences - UNESP, Botucatu Campus-SP. The experimental design was completely randomized, composed of five treatments: 0, 50, 100, 200 and 400 mg of the active ingredient (a.i.) of ProCa, with 4 replicates of 30 seedlings. Treatments were applied with a manual CO2 sprayer when seedlings completed 20 days after sowing. Ten days after applying the treatments, seedling growth analysis, SPAD index, gas exchange, chlorophyll a fluorescence and biochemical analyses were all performed. From the results obtained, the conclusion was that ProCa concentrations inhibited seedling growth without compromising the photosynthetic apparatus. |
| Abstract: | O objetivo do trabalho foi estudar os efeitos de diferentes concentrações do regulador vegetal proexadiona cálcica (ProCa) no controle do crescimento de mudas de tomateiro. O experimento foi conduzido no viveiro de mudas florestais da Faculdade de Ciências Agronômicas – UNESP, Campus de Botucatu–SP. O delineamento experimental foi o inteiramente casualizado, composto por cinco tratamentos: 0, 50, 100, 200 e 400 mg de ingrediente ativo (i.a.) de ProCa, com quatro repetições de 30 mudas cada. Os tratamentos foram aplicados com pulverizador manual de CO2 quando as mudas completaram 20 dias após a semeadura. Dez dias após a aplicação dos tratamentos foram realizadas análises de crescimento das mudas, índice SPAD, trocas gasosas, fluorescência da clorofila a e análises bioquímicas. Pelos resultados obtidos foi possível concluir que as concentrações de ProCa inibiram o crescimento das mudas, não comprometendo o funcionamento de seu aparato fotossintético. |
