Serological Identification of Virus in Watermelon Production Fields in the Tocantins State BABT
Aguiar,Raimundo Wagner de Souza; Rodrigues,Adelmo; Portella,Augustus Caeser Franke; Lopes,Magnolia de Mendonça; Lima,Mirtes Freitas; Resende,Renato de Oliveira; Nagata,Tatsuya.
Watermelon (Citrullus lanatus) cultivated in almost all tropical and subtropical regions of the world, has its largest output in China, and then, according to FAO data, Turkey, Iran and Brazil, being one of the main crops cultivated in State of Tocantins, Brazil. In this work was investigated the occurrence and distribution of the watermelon viruses, totaling 752 samples taken in a stratified experimental design in four representative regions of production: Gurupi (150), Lagoa da Confusao (232), Formoso do Araguaia (265) and Porto Nacional (105). The sampling and collecting the leaves of plants with the presence of symptoms were performed once a week during the entire cultivation cycle. As a result, were observed by Dot-ELISA method, different types of...

Micropropagation of an elite F1 watermelon (Citrullus lanatus) hybrid from the shoot tip of field grown plants BABT
Khalekuzzaman,Mohammad; Khatun,Marufa; Rashid,Mohammad Harunur; Sheikh,Mominul Islam; Sharmin,Shamima Akhtar; Alam,Iftekhar.
The aim of this work was to develop a protocol for rapid micropropagation of an elite F1 hybrid watermelon cultivar using shoot tip of field-grown plants. Maximum frequency (73%) of shoot tip showed growth response in MS medium supplemented with 5 mg l-1 benzyl adenine (BA) and 0.1 mg l-1 indole-3 acetic acid (IAA). Upon transfer to cytokinin-enriched medium, the cultures produced multiple shoots and 2.0 mg l-1 BA was optimum in this respect. Addition of gibberellic acid (GA3) in the multiplication medium resulted in better growth of shoots. Rooting rate was 100% when shoots were obtained from second subculture were cultured in medium with 1.0 mg l-1 indole-3 butyric acid (IBA). The shoots produced more roots with increasing number of subcultures. About...

Production of crystallized fruit from watermelon rind Ciencia e Investigación Agraria
Gontero,Mauro; Brandelli,Adriano; Zapata Noreña,Caciano.
The aim of this work was to produce crystallized fruit from watermelon rind. The following procedure was developed: the outer peel was removed; the material was sliced into 7 mm cubes, blanched for, 0, 5 and 10 minutes, and then treated with 10% sodium chloride solution. This product was treated with solutions of sucrose (30 to 72 °Brix), and dried in a hot air dryer at different temperatures (40, 60 and 80 °C). Products were then analyzed by a sensory panel. The experimental design used was randomized blocks and the results were analyzed by the Tukey's test. The best acceptance of the sensory panel was for the product obtained by 5 minutes blanching followed by drying at 60 °C, whose intensity values for appearance, flavor and gummosis were between 6 and 7.
