ABSTRACT Using nematode-resistant and/or -tolerant rootstock is a strategy that has maintained guava cultivation feasible in the irrigated perimeters of Brazilian semi-arid region. The objective was to evaluate production, gas exchange, and fruit quality ‘Paluma’ with without nematode-tolerant under different irrigation depths production periods. experimental design randomized blocks, mixed 2 ×...

The guava (Psidium guajava L.), which has unique and quince-banana like flavor, is an economically important subtropical fruit in many tropical countries on all seasons. Volatile constituents from three Colombian varieties of guava fruits: Coronilla (commonly named guayaba común), Palmira ICA-1 (commonly named guayaba pera) and Glum Sali (commonly named guayaba manzana) were isolated by headspa...

Background: Edible coating is an effective and widely used approach for preservation of quality fruits.

Methods: Chitosan nanoemulsion was prepared ultrasonication guava samples were dipped in ...

BACKGROUND The purpose of this study is to investigate cardiovascular benefits of juices obtained from two commonly consumed fruits in Thailand, Pachyrhizus erosus, L. (yam bean) and Psidium guajava, L. (guava), by examining their acute cardiovascular effects in healthy volunteers.

The infesting species and their infestation indices of fruit flies were determined for eleven guava genotypes (Psidium guajava L.). From March to April 2000, ten mature fruits of each genotype were harvested at weekly intervals from insecticide unsprayed trees located in the municipality of Monte Alegre do Sul, SP, Brazil. Fruits were brought to the laboratory, weighed and placed in individual ...

The present investigation was carried out to appraise the levels of total phenols and vitamin C as well as antioxidant potential at three different ripening stages (un-ripe, semi-ripe and fully-ripe) of guava (Psidium guajava L.) fruit collected from three different geographical regions of Pakistan (Islamabad, Faisalabad and Bhakkar). The antioxidant potential of guava fruit extracts was assess...

The behavioral and electrophysiological responses of males and females of the Mexican fruit fly Anastrepha ludens (Loew) to guava ( Psidium guajava L.) volatiles were investigated in laboratory tests. Males and females were significantly more attracted and landed more often on guava fruits than yellow spheres used as control in the wind tunnel. Also, both sexes were more attracted to Porapak Q ...

The objectives of this study were to evaluate the hydrophilic antioxidant activity (AOAH) and the lipophilic antioxidant activity (AOAL); and their correlations with vitamin C, and total phenolic and beta-carotene contents in fresh guava fruits of one white flesh clone ('Allahabad Safeda') and three pink flesh clones ('Fan Retief', 'Ruby Supreme,' and an advanced selection). A ferric reducing a...

The ascorbic acid content of selected fruits was collected from a local market Mandya and Maddur in these were determined by volumetric method using 2,6-dichlorophenol indophenol. results obtained confirms the presence fruits. highest yield found Guava lowest different tested. These suggest that wide variety can be consumed to meet daily requirements vitamin C cost-effective manner.

Psidium guajava (Guava) could be an ancient remedy used for a variety of health conditions. Research suggests that guava fruits and leaves might have advantages.
