Resumo: Water stress in tomato plants may cause the incidence of blossom-end rot. This study aimed to analyze the effect of abscisic acid leaf application for increasing the calcium uptake in irrigated tomato (‘Santa Clara’ cultivar) in the field, as a possible mechanism of blossom-end rot inhibition. The treatments consisted of four irrigation levels (25 %, 50 %, 75 % and 100 % of the crop water requirements to fulfil the crop evapotranspiration) and two abscisic acid doses (0 mg L-1 and 500 mg L-1). The fruits were harvested at 15 and 30 days after the anthesis and evaluated for calcium content and percentage of blossom-end rot. The application of abscisic acid increased the calcium partition to the distal region of the fruits at 30 days after the beginning of flowering, as well as reduced the incidence of blossom-end rot by 86 %, when compared with plants not treated with abscisic acid. It is possible to conclude that the foliar application of abscisic acid can significantly reduce the incidence of blossom-end rot.

Objetivou-se analisar o efeito da aplicação foliar de ácido abscísico no aumento da absorção de cálcio em tomate (cultivar ‘Santa Clara’) sob irrigação no campo, como um possível mecanismo de inibição da podridão apical. Os tratamentos consistiram de quatro níveis de rega (25 %, 50 %, 75 % e 100 % das necessidades de água para suprir a evapotranspiração da cultura) e duas doses de ácido abscísico (0 mg L-1 e 500 mg L-1). Os frutos foram colhidos aos 15 e 30 dias após a antese e avaliados para a concentração de cálcio e porcentagem de podridão apical. A aplicação de ácido abscísico aumentou a partição de cálcio para a região distal dos frutos aos 30 dias após o início da floração, bem como reduziu a incidência de podridão apical em 86 %, quando comparada a plantas sem a aplicação de ácido abscísico. Conclui-se que a aplicação foliar de ácido abscísico pode reduzir significativamente a incidência de podridão apical.Escola de Agronomia - Universidade Federal de Goiás2018-11-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/52048Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 48, n. 4, Oct./Dec. 2018; 414-419Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 48, n. 4, out./dez. 2018; 414-419Pesquisa Agropecuária Tropical; v. 48, n. 4, out./dez. 2018; 414-4191983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/52048/26643Copyright (c) 2018 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessAgostinho Balate, CarlosCorrea de Souza, DouglasVilela Resende, LucianeTonetto de Freitas, Sergio2020-07-13T19:33:45Zoai:ojs.revistas.ufg.br:article/52048Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:20.387080Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true
