Redução de sementes do tangor 'Murcote' com a aplicação de biorreguladores durante o florescimento

Abstract: O presente ensaio foi conduzido em cultivo comercial do tangor 'Murcote' e teve por objetivo avaliar a atuação dos biorreguladores 2,4-D (auxina), NAA (auxina), GA3 (giberelina) e BA (citocinina), na redução do número de sementes, sem afetar a qualidade dos frutos cítricos. Os tratamentos foram: Testemunha; 10 e 20 mg.L-1 de 2,4-D; 100, 150 e 200 mg.L-1 de NAA, 100 e 200 mg.L-1 de GA3 e 20 e 40 mg.L-1 de BA. Verificou-se que nenhum dos reguladores vegetais influenciou na qualidade dos frutos de tangor 'murcote… Show more

“…Reduction in seed number by GA 3 application might be due to reduced fertilization by either increasing ovule abortion or decreasing pollen tube germination (Mesejo et al, 2008). Similarly a reduction in seed number by GA 3 application was reported in Murcott Tangore (Domingues and Rodrigues, 2007) and Afourer mandarin (Gambetta et al, 2013). More seed number in Kinetin treated fruit might be due to the positive impact of Kinetin on source sink relation in reproductive development by promopting photo assimilates production and partitioning (Kriedemann, 1968).…”
