Índice de pegamento de frutos em goiabeiras

Abstract: A produção das plantas está relacionada com o florescimento e frutificação, podendo variar em função de fatores genéticos, ambientais e de manejo dos pomares. Informações dessa natureza, tal como índice de pegamento de frutos, são importantes na caracterização biológica, estudos comparativos de cultivares e predição de safra. O objetivo deste estudo foi determinar o índice de pegamento de frutos em goiabeiras adultas das cultivares Pedro Sato, Paluma e Rica, em pomares comerciais de elevada produtividade, loca… Show more

“…The lowest values were observed in plants pruned on September 26 and October 11, among which there was no significant difference. Corrêa et al (2002) evaluated the fixation index fruits in 'Pedro Sato', 'Paluma' and 'Rica' guava trees in Taquaritinga, SP and found average values of 32.3%, 18.7% and 12.2%, respectively. The values found by these authors were lower than those obtained in this study.…”

“…With this data, the fixation index fruits (FIF) -fruit set was determined, using the formula proposed by Corrêa et al (2002): FIF = [(NFF/NFB) 100]. A total of 10 fruits per experimental plot were selected and measured weekly using a digital caliper.…”

“…Even assuming that the maximum fixation index of the guava fruit is 20% during flowering and fruiting phases (7,27), all buds and fruits must be protected. As far as new control methods or new rust resistant cultivars are developed, fungicides should be used in the susceptible phases to keep as many healthy buds and fruits as possible to ensure the highest guava yield.…”

“…O comportamento das plantas quanto ao florescimento e à frutificação pode variar em razão de uma série de fatores (genéticos, ambientais e de manejo dos pomares) tais como tipo e posição das flores nos ramos, deiscência da antera, clima, solo, espaçamento entre plantas, estado nutricional e poda (Corrêa et al, 2002).…”
