Repeatability of agronomic and morphological characteristics in ornamental pepper
Provedor de dados: 75
Autores: Ribeiro,Wellington S; Costa,Lucas C; Dias,Fabíola S; Silva,Francisco CS; Pinto,Cleide MF; Finger,Fernando L.
Breeding programs seek to reduce the time spent assessing characteristics more times than necessary. However, this reduction should in no way undermine the representativeness and reliability of the information. Thus, an important success factor in breeding programs is the knowledge of the ideal number of assessments needed to evaluate commercially important characteristics in each species or population. In this context, this study aimed to determine the repeatability coefficient of eight biometric traits in four populations of ornamental pepper, seeking to increase the efficiency of evaluation and selection processes. There was no significant influence of the calculation method used over the estimate of the repeatability coefficient. The results indicated...

1-MCP efficiency in quality of ornamental peppers
Provedor de dados: 75
Autores: Ribeiro,Wellington S; Carneiro,Clebson dos S; França,Christiane de Fátima M; Pinto,Cleide Maria F; Lima,Paula Cristina C; Finger,Fernando L.
ABSTRACT 1-MCP has been effectively used as an antagonist of ethylene deleterious actions in flowers and ornamental plants. The objective was to evaluate the efficiency of 1-MCP (0.0, 0.5, 1.0 and 1.5 g m-3) in maintaining post-production quality of exogenous ethylene sensitive ornamental pepper. Two commercial varieties were evaluated: Pimenta Colorida and Pimentão Ornamental, both Capsicum annuum. The pre-treatment with 1-MCP, regardless of the applied concentration, was effective in blocking the ethylene action reducing the leaves abscission, flowers and fruits of both genotypes by 100%. Plants pretreated with 1-MCP had postproduction life increased by eight and nine days for Pimenta Colorida and Pimentão Ornamental, respectively. The 1-MCP application...

Paclobutrazol application in potted ornamental pepper
Provedor de dados: 75
Autores: Ribeiro,Wellington S; Carneiro,Clebson dos S; França,Christiane de Fátima M; Pinto,Cleide Maria F; Lima,Paula Cristina C; Finger,Fernando L; Costa,Franciscleudo B da.
ABSTRACT Within the genetic variability of the Capsicum genus there are plants with ornamental potential, but awry height required by the market. Paclobutrazol (PBZ), gibberellin retardant and growth inhibitor, is normally used as alternative to reduce plant height. The objective was to evaluate the PBZ (0, 25, 50 and 75 mg L-1) effect on plant height of eight pepper genotypes. Seven accessions [BGH 1032, BGH 1039, BGH 7073 (C. annuum), BGH 4285, BGH 4199, BGH 4355 and BGH 6371 (C. chinense)] of the germplasm bank from Universidade Federal de Viçosa and one access [MG 302 (C. annuum)] from the germplasm bank of the Empresa de Pesquisa Agropecuária de Minas Gerais were evaluated. The PBZ application was ineffective in altering plant architecture of BGH...

Sensitivity of ornamental pepper to ethylene
Provedor de dados: 75
Autores: Ribeiro,Wellington S; Carneiro,Clebson dos S; França,Christiane de Fátima M; Pinto,Cleide Maria F; Lima,Paula Cristina C; Finger,Fernando L; Costa,Franciscleudo B da.
ABSTRACT The genus Capsicum has varying levels of sensitivity to ethylene. Variability knowledge allows planning post-production methodologies of potted pepper plants and can be used in breeding programs. The objective of this study was to evaluate the ethylene sensitivity of three ornamental pepper genotypes of the germplasm bank of Universidade Federal de Viçosa. Pepper plants were exposed to 10 μL L-1 ethylene during 48 hours. The flowers were highly sensitive to exogenous ethylene in all genotypes except Pimenta colorida which was moderately sensitive. Regarding leaf abscission, Pimenta colorida and Pimentão ornamental are classified as highly sensitive to ethylene application. Already the fruits responded with the early appearance of the typical...
