Optimization of in vitro multiplication for exotic banana (Musa spp.) in Pakistan

The present attempt aimed to optimize micropropagation protocols supplemented with different concentrations and combinations of benzylaminopurine (BAP) (0, 2, 4, 6 mg L-1) and indole acetic acid (IAA) (0.5 and 1.0 mg L-1). Exotic banana (Musa spp) genotypes GCTCV-215 (AAA), ‘Yangambi’ Yangambi Km-5 (AAA) and FHIA-23 (AAAA) were used in research work. Experiments were conducted at Plant Tissue Culture...

Growth performance and nutrient quality of three Moringa oleifera accessions grown as potplant under varied manure rates and watering intervals

Growth performance and nutrient quality of three Moringa oleifera accessions grown as potherbs under varied manure rates and watering intervals were investigated at the Department of Crop Science, University of Nigeria, Nsukka. The treatments included three accessions of Moringa (Awo-Anaekpa, Idere and Kano), three pig manure rates (0, 10 and 20 t/ha) and three watering intervals (3, 4 and 5 days). These were laid out...

Provenance variation in growth and genetic potential of Aquilaria malaccensis under nursery condition

Aquilaria malaccensis Lam. is commonly known as Agarwood which is distributed in the Indo-malesian genus Aquilaria of family Thymelaeaceae known to produce resin-impregnated heartwood that is fragrant and highly valuable. Agarwood is reputed to be the most expensive wood in the world. Twenty two open pollinated families in A. malaccensis were selected and evaluated for growth attributes and genetic divergence. The...

Application of zein antimicrobial edible film incorporating Zataria multiflora boiss essential oil for preservation of Iranian ultrafiltered Feta cheese

Zein based edible film was developed and incorporated with Zataria multiflora boiss essential oil. Mechanical and microbiological characteristics of this biofilms were measured. Increasing concentration of antimicrobial agent in film reduced stretchability, tensile strength and elongation, however increased the thickness and water vapor transmission parameters (P<0.05). Addition of Z. multiflora boiss essential oil,...

Minimally processed fruit salad enriched with Lactobacillus acidophilus: Viability of anti-browning compounds in the preservation of color

Minimal processing promotes browning of some vegetal tissues due to cell membrane disruption, which results in the release of oxidative enzymes. This study evaluated the efficiency of citric acid, ascorbic acid, sodium metabisulfite and L-cysteine ​​hydrochloride to retard enzymatic browning of minimally processed fruit salad and enriched this product with Lactobacillus acidophilus LA-5. Control treatment was fruit...

Physico-chemical and rheological properties of prato cheese during ripening

The influence of storage temperature (6, 12 and 18°C) on texture parameters of Prato cheese were evaluated during 22 days of ripening. A reduction of firmness, gumminess and elasticity was observed; however, cohesiveness and adhesiveness increased. With the increasing temperature, firmness and gumminess reduced, whereas the elasticity, cohesiveness and adhesiveness did not change. It can be concluded that storage...

Evaluation of the postharvest quality of Cagaita fruits (Eugenia dysenterica DC.) coated with chitosan and associated with refrigeration

Cagaita fruits are subject to seasonality and perishability. This work aims to use scanning electron microscopy (SEM) to evaluate the physicochemical characteristics, texture, color and physical structure of cagaita fruits coated with different chitosan concentrations. The fruits were divided as follows: T0 (uncoated fruits), T1 (fruits coated with 1% (v/v) chitosan), T2 (fruits coated with 2% (v/v) chitosan) and T3...

Effects of Nigeria Ekete light crude oil on plasma electrolytes, packed cell volume (PCV) and lipids profile in wistar (Rattus norvegicus) rats

Hydrocarbon is known to alter blood parameters; some of these blood parameters may affect the activities of certain systems like cardiovascular system. Hydrocarbon gets into man and animal either through ingestion of contaminated food and water, bio-concentration through food chain, occupational exposure or by using hydrocarbon products. Effects of crude oil on plasma electrolytes, packed cell volume (PCV) and plasma...

Therapeutic role of glucogalactan polysaccharide extracted from Agaricus bisporus on trimethyltin chloride induced neuropathy in rats

Trimethyltin (TMT) chloride induces limbic system neuro-degeneration, resulting in behavioral alterations including cognitive deficits. The aim of the present study was to investigate the effect of glucogalactan polysaccharide (GA) which purified from the roots of mushroom Agaricus bisporus extract on the Trimethyltin Chloride (TMT) induced neuropathy in rats.  Adult male rats (200 ±10 g) were divided into...
