13. Resistência de pimentão ao PepYMV e PepYMV-Lins e obtenção de híbridos resistentes
RESUMO O Pepper yellow mosaic virus (PepYMV) é o mais importante Potyvirus infectando plantas do gênero Capsicum no Brasil. Perdas podem chegar a 100% caso a infecção ocorra no início do cultivo. A resistência genética é a principal forma de controle desta virose. Em 2009 um novo isolado denominado PepYMV-Lins foi detectado quebrando a resistência g

14. Productivity and photosynthetic pigments in bell pepper plants grown in soil with biofertilizer and protected against water loss
ABSTRACT The search for techniques that maximize the use of water is becoming necessary for the sustainability of agriculture in semi-arid areas. In this sense, the present work aimed to evaluate the effects of soil protection against water loss and the use of bovine biofertilizer on fruit production and chlorophyll content in bell pepper plants. The experim

15. Selection in segregating populations of ornamental pepper plants (Capsicum annuum L.) using multidimensional scaling
ABSTRACT Multidimensional scaling is a multivariate analysis technique that can be used to exploit genetic diversity, aiming at the selection of Capsicum genotypes with desirable characteristics for in-pot ornamental purposes. This work aimed to select genotypes with ornamental potential within F4 populations of ornamental pepper plants. Three F4 families we

16. Genetic variability in peppers accessions based on morphological, biochemical and molecular traits
ABSTRACT The evaluation of genetic diversity among the accessions of a germplasm collection results in information about promising materials suitable for breeding programs. Thus, the goal of this work was to characterize Capsicum baccatum accessions from different Brazilian regions, based on morphological, biochemical and molecular traits, aiming to support

17. Yield and morphological attributes of bell pepper fruits under biological fertilizers and application times
ABSTRACT Bell pepper (Capsicum annuum) is one of the most consumed vegetables around the world. Balanced fertilization is essential for growing this vegetable. The objective of this study was to evaluate the yield and morphological attributes of bell pepper under doses and times of application of biological fertilizers. Two experiments were carried out with

18. GROWTH OF ORNAMENTAL PEPPER IN COLORED CONTAINERS UNDER PROTECTED ENVIRONMENTS
ABSTRACT Ornamental pepper plants produced in containers under protected environments have high added value. We carried out research with an aim to evaluate the growth and development of ornamental pepper in containers of different colors under two protected environments, both with thermal-reflective screens under a polyethylene film: one with 18–22 % shad

19. New Diesters Derived from Piperine: in silico Study and Evaluation of Their Antimicrobial Potential
Piperine, previously extracted from black pepper (Piper nigrum L.), was used as a precursor for the synthesis of twelve new diester derivatives. The final products were obtained through the bimolecular nucleophilic substitution reaction (SN2) of the alkyl 2-chloroacetates and the salt of piperic acid, obtained from the basic hydrolysis of piperine. The compo

21. Multi-Element Evaluation in Black Pepper (Piper nigrum L.) According to the Processing
Black pepper is one of the most consumed spices worldwide and the evaluation of trace elements content is essential to promote consumer safety. In this study, concentrations of the elements As, Cd, Co, Cu, Fe, Mn, Mo, Ni, Pb, Se, V and Zn was determined in samples of black peppercorn (n = 25) and ground black pepper (n = 25) to verify how processing affects

22. Sensitivity of ornamental pepper to ethylene
RESUMO As plantas do gênero Capsicum têm níveis variáveis de sensibilidade ao etileno. O conhecimento desta variabilidade permite o planejamento de metodologias de pós-produção de pimenteiras em vaso e pode ser usado em programas de melhoramento genético. O objetivo foi avaliar a sensibilidade ao etileno de três genótipos de pimenteiras ornamentais
