A field experiment was conducted to investigate the influence of composted pineapple residue return (CPRR) on soil bio-chemical properties and the growth performance of next-cropped pineapple plants. The results suggested that CPRR markedly decreased the soil bulk density and increased the contents of available P and K. CPRR significantly increased the abundance of bacteria and actinomycetes, a...

In a series of screening trials a number of new, non-mercurial fungicides have shown promising results in controlling pineapple disease of sugarcane (Ceratocystis paradoxa). Several of the fungicides tested are as effective as Aretan and Benlate and are now registered for use in sugarcane. Growers now have a choice of effective non-mercurial fungicides for sett dip treatment. Poor germination o...

Recent studies have shown that dietary fiber and polyphenols of vegetables and fruits improve lipid metabolism and prevent the oxidation of low density lipoprotein cholesterol (LDL-C), which hinder the development of atherosclerosis. The goal of this study was to measure the total polyphenol and dietary fiber contents of some tropical fruits (i.e., pineapple, wax apple, rambutan, lichi, guava, ...

A comparative study on diurnal changes in metabolite levels associated with crassulacean acid metabolism (CAM) in the leaves of three CAM species, Ananas comosus (pineapple), a hexose-utilizing species, and Kalanchoë daigremontiana and K. pinnata, two starch-utilizing species, were made. All three CAM species showed a typical feature of CAM with nocturnal malate increase. In the two Kalanchoë s...

Two methods were used to develop pineapple microsatellite markers. Genomic library-based SSR development: using selectively amplified microsatellite assay, 86 sequences were generated from pineapple genomic library. 91 (96.8%) of the 94 Simple Sequence Repeat (SSR) loci were dinucleotide repeats (39 AC/GT repeats and 52 GA/TC repeats, accounting for 42.9% and 57.1%, resp.), and the other three ...

Differences in carbohydrate contents and metabolizing-enzyme activities were monitored in apical, medial, basal and core sections of pineapple (Ananas comosus cv. Comte de paris) during fruit development and ripening. Fructose and glucose of various sections in nearly equal amounts were the predominant sugars in the fruitlets, and had obvious differences until the fruit matured. The large rise ...

Storage of 42° Brix Pineapple and Valencia orange concentrates at 40° F. resulted in in creased gelation, clarification, and apparent pulp content, whereas pectin decreased. Total glycosides, as hesperidin, remained constant in these products during storage. The experi mental packs heated at 1and 2-fold were more stable than those heated at 3and 4fold; also all of the Valencia concentrates, con...

The influences of storage temperature and modified O2 and CO2 concentrations in the atmosphere on the post-cutting life and quality of fresh-cut pineapple (Ananas comosus) were studied. Temperature was the main factor affecting post-cutting life, which ranged from 4 days at 10 ◦C to over 14 days at 2.2 and 0 ◦C. The end of post-cutting life was signaled by a sharp increase in CO2 production fol...

The present study examined the perception of smallholder pineapple farmers on Global GAP standard compliance, assessed compliant farmers’ rate of adherence to standard requirements, and compared the average farm profit of Global GAP compliant and non-compliant pineapple farmers in Akuapem South Municipal Area of Ghana. The study used mainly farm level data solicited from 150 randomly selected p...

Bifidobacterium longum was microencapsulated by extrusion technique and added in fresh milk tofu and pineapple juice. Microencapsulation of B. longum with Eleutherine americana extract, oligosaccharides extract, and commercial fructo-oligosaccharides was assessed for the bacterial survival after sequential exposure to simulated gastric and intestinal juices, and refrigeration storage. Microenca...
