1. CARACTERIZACIÓN MORFOLÓGICA DE GERMOPLASMA DE GUAYABOS DE MÉXICO: IMPLICACIONES EN SU CONSERVACIÓN Y MEJORAMIENTO GENÉTICO
ABSTRACT Guavas (Psidium guajava L.) growing throughout Mexico show broad morphologic and productive variation due the crop is commonly sexual-propagated. The characterization of genetic diversity of Mexican guava germplasm will allow identify potential parents for genetic improvement as well as the production of new clonal cultivars. In this work 88 guava

2. Ethanol on the postharvest control of anthracnose in ‘Kumagai’ guava
ABSTRACT The aim of this study was to evaluate the effects of ethanol on the control of Colletotrichum spp. in ‘Kumagai’ guava and on the fruit physical-chemical attributes. For this purpose, three assays were carried out. For the first assay, fruit were exposed to ethanol vapor (0, 1, 2, 4, and 8 mL∙kg-1), applied in hermetic containers. On the second

3. Effect of CaCl2 and controlled atmosphere storage on phytochemical attributes of Guava
Abstract Guava is very delicate and alluring fruit which is being ignored since very long time despite of highly nutritious fruit and rich source of Vitamin C. It contains Vitamin C 2-3 times more than orange. Naturally the guava fruit is enriched with vitamin C and polyphenoles. Guavas fruits after harvesting were dunked in solutions of CaCl2 (1, 2 and 3%)

4. Temporal progress and spatial patterns of quiescent diseases in guava influenced by sanitation practices
ABSTRACT: Postharvest diseases are a major problem in guava crops as the symptoms normally appear during fruit ripening. This study aimed to detect and characterize the temporal dynamics and spatial patterns of the most important guava diseases in orchards with and without removal of crop residues as a sanitation practice. The experiment was conducted in an

5. Incidence of postharvest diseases on 'Kumagai' and 'Pedro Sato' guavas at wholesale markets in Brazil
The time after harvest is characterized by physiological changes in the fruit that favor the occurrence of postharvest diseases, which are often observed only after sale. As a result, the damage resulting from the action of quiescent pathogens can be underestimated. From November to April of the years 2009/2010 and 2010/2011, a survey was conducted to quanti

6. Doenças quiescentes em goiabas: quantificação e controle pós-colheita / Quiescent diseases in guava: quantification and post-harvest control
Post-harvest diseases in guavas may represent damages from 20 to 40%. Environmental conditions and disease management, before or after harvesting, are among their major causes. Standards proposed by the Integrated Production Fruit (IPF) ensure fruit quality and sustainable production with rational use of agrochemicals. Using the white-fleshed variety Kumagai

7. EFEITOS DOS SUBPRODUTOS DA AROEIRA E DO BIOFILME A BASE DE QUITOSANA NA PÓS-COLHEITA E CONTROLE DA ANTRACNOSE EM GOIABAS PALUMA.
Guava is cultivated in many parts of the world, but the high perishability and the incidence of diseases such as anthracnose limits its commercialization. The challenge to the method used to attempt to solve these problems, the use of chemicals, has instigated the conduct of research with products. Thus, plantas have been studied mant times have active subst

8. Doenças da goiabeira no cerrado.
RESUMO: Várias doenças atacam a goiabeira (Psidium guajava L.) cultivada nas regiões de abrangência do Cerrado. A bacteriose (Erwinia psidii) é a mais importante. No Distrito Federal, essa doença pode provocar perdas de até 85% na produção do período de entressafra. Outras doenças como a antracnose (Colletotrichum gloeosporioides), ferrugem (Pucci

9. Determinación de vitamina C, compuestos fenólicos totales y actividad antioxidante de frutas de guayaba (Psidium guajava L.) cultivadas en Colombia
Some physicochemical parameters, vitamin C, total phenolic compounds and antioxidant activity (AA) measured by ABTS, FRAP and DPPH methods were determinated in four different varieties of ripe guava produced in Colombia. Samples were statistically similar in their titratable acidity. Soluble solids were statistically similar and higher in "Pear", "Pink Regio

10. Processamento mínimo de goiabas: estádio de maturação e controle de senescência / Minimal processing of guavas: ripening stage and senescence control
A goiaba é uma fruta saudável para consumo, oferece níveis elevados de licopeno, vitamina C e fibras e constitui-se numa boa opção ao processamento mínimo. Entretanto, o ponto de colheita e o controle da senescência são questões importantes para o sucesso do processamento. O objetivo do trabalho foi definir o melhor estádio de maturação para o pr

11. Infecção e colonização de goiabas por Colletotrichum gloeosporioides e Colletotrichum acutatum sob diferentes temperaturas e períodos de molhamento / Infection and colonization of guavas by Colletotrichum gloeosporioides and Colletotrichum acutatum under different temperatures and wetting periods
The main causal agents of Anthracnose in guava are Colletotrichum gloeosporioides and C. acutatum. Although anthracnose is the main postharvest disease affecting guava, little is known about the influence of environmental variables on its development. Consequently, the objective of the present study was to determine the influence of environmental factors on

12. Qualidade pós-colheita da goiaba vermelha (Psidium guajava L.) submetida ao tratamento quarentenário por irradiação gama / Postharvest quality of red guava (Psidium guajava L.) submitted to quarantine treatment by gamma irradiation
Red guava is not a well-known fruit by importing markets; however, it has a great commercial potential, since it is considered one of the most complete fruits in terms of nutritional quality. However, the presence of fruit-flies in fruits leads importing countries to impose commercial restrictions due to phytosanitary risk. The USA permit the use of irradiat
