Alternative title
Effect of artificial defoliation on the yield of two indeterminate bean (Phaseolus vulgaris L.).
Abstract
Dois cultivares de feijao de hábito de crescimento indeterminado "S-182--N" e "Carioca" foram submetidos a 33 e 66% de desfolhamento artificial. quando as plantas tinham 20. 30, 40. 50 ou 60 dias de idade. Verifi-cou-se que 66% de desfolhamento é muito prejudicial ao rendimiento da cultura, quando realizado nos estádios de florescimento e formação das vagens. O cv. "Carioca" é algo mais tolerante ao desfolhamento que o "S-182—N". Two cultivars of indeterminate growth habit 'S-182--N' and 'Carioca' were subjected to 33 and 66% artificial defoliation when the plants were 20, 30, 40, 50 or 60 days old. It was verified that 66% defoliation is very It was verified that 66% defoliation is very damaging to the yield of the crop, when performed in the stages of flowering and pod formation. The cv. "Carioca" is somewhat more tolerant to defoliation than "S-182-N". Dos cultivares de hábito de crecimiento indeterminado 'S-182--N' y 'Carioca' fueron sometidos a defoliación artificial del 33 y 66% cuando las plantas tenían 20, 30, 40, 50 o 60 días de edad. Se comprobó que una defoliación del 66% es muy perjudicial para el rendimiento del cultivo cuando se realiza en las fases de floración y formación de vainas. El cv. "Carioca" es algo más tolerante a la defoliación que "S-182-N".
