Ação de reguladores vegetais no desenvolvimento, aspectos nutricionais, anatômicos e na produtividade do feijoeiro (Phaseolus vulgaris cv. Carioca)

Abstract: Neste estudo foram determinados os efeitos de reguladores vegetais na altura, na formação foliar, nos teores de nutrientes acumulados (N total, protéico e amínico; P, K e Ca, na anatomia e na produtividade do feijoeiro 'Carioca', sob condições de casa de vegetação. A semeadura foi realizada em 22/07/88, sendo que em 22/08/88 foi efetuada a pulverização das plantas com giberelina 50ppm, ácido naftalenacético 50ppm, chlormequat 1000ppm, daminozide 3000ppm, chlorflurenol 100ppm e Figaron 50ppm, tendo-se mantido u… Show more

“…Even though an increase in the number of leaves was verified after treatment with GA 3 by Castro et al (1990) for bean plants, and by Harb (1992) for Vicia faba, similar results were not obtained in the present work for soybean (data not shown), as well as for pea by Saimbhi et al (1975). This demonstrates that comparisons between different species should not be made, because the response could be related either to the different application techniques and rates (King et al, 2000), or to the utilized soybean cultivar (Nalawadi et al, 1973).…”

“…The application of daminozide in beans, in the stage of three leaves, or early flowering, reduced plant height, increasing the number of pods per plant, weight of 1000 seeds and grain yield (Castro et al, 1990).…”

“…Na Figura 1 observa-se acréscimo no número de folhas a partir de 86 dias do plantio no tratamento com GA 3 . Castro et al (1990) observaram em feijão 'Carioca' aos 14 e 21 dias após a aplicação de giberelina a 50 mg L -1 , aumento no número de folhas. O tratamento com cloreto de mepiquat teve o número de folhas superior à testemunha nos períodos entre 73 e 112 dias após o plantio.…”

“…O tratamento com GA 3 , apesar do grande número de flores emitidas e do número de vagens levemente superior a testemunha, apresentou matéria seca de vagens inferior a mesma durante todo ciclo de desenvolvimento de vagens. Castro et al (1990) observaram redução na massa de vagens de feijão 'Carioca' tratadas com NAA e cloreto de clormequat.…”
