Watermelon fusarium wilt caused by Fusarium oxysporum f.sp. niveum (FON) is a 13 destructive soil-borne disease throughout the world leading to serious economic losses and limit 14 watermelon production. Cuminic acid, extracted from the seed of Cuminum cyminum L., belongs to 15 benzoic acid analogues. In this study, the median effective concentration (EC50) values for cuminic 16 acid in inhibit...

This paper reports the potential of watermelon seed as a natural coagulant for water treatment. It was aimed at identifying watermelon seed as a possible replacement for alum and other synthetic polyelectrolytes in treating water. Laboratory scale studies using jar test experiments were performed on medium turbid water to determine the effect of dosage, pH stirring time and speed on coagulation...

ABSTRACT To assess the diversity of Acidovorax avenae subsp. citrulli, 121 strains from watermelon, cantaloupe, and pumpkin were compared using pulse field gel electrophoresis of SpeI-digested DNA and gas chromatographic analysis of fatty acid methyl esters. Twenty-nine unique DNA fragments resulted from DNA digestion, and 14 distinct haplotypes were observed. Based on cluster analysis, two sub...

ABSTRACT A novel whitefly-transmitted member of the family Potyviridae was isolated from a squash plant (Cucurbita pepo) with vein yellowing symptoms in Florida. The virus, for which the name Squash vein yellowing virus (SqVYV) is proposed, has flexuous rod-shaped particles of approximately 840 nm in length. The experimental host range was limited to species in the family Cucurbitaceae, with th...

Melatonin, a pleiotropic signal molecule, has been shown to play important roles in the regulation of plant growth, development, and responses to environmental stresses. Since a few species have been investigated to unveil the effect of exogenous melatonin on salt stress, the underlying mechanism of melatonin-mediated salt stress tolerance in other plant species still remains largely unknown. I...

This study was conducted to determine the influence of L-tryptophan (LTRP) applied to soil on the yield of two watermelon (Citrullus Lanatus L.) and one muskmelon (Cucumis melo L.) cultivars. Experiments were established in which L-TRP was applied to seedlings as a soil drench in the glasshouse ranging from 6 × 10 to 60 mg·kg soil; the seedlings were transplanted into the field 2 weeks later. T...

Iron deficiency anaemia secondary to gastrointestinal bleeding is very common in the elderly. Gastric antral vascular ectasia (GAVE) syndrome, also known as watermelon stomach is an uncommon but significant cause of acute or chronic gastrointestinal blood loss in the elderly. It is characterised endoscopically by "watermelon stripes." It is more common in females than males, and manifests mostl...

The model of vicious walkers was introduced by Fisher [4]. He gave a number of applications in physics, such as modelling wetting and melting processes. In general, the model of vicious walkers is concerned with p random walkers on a d-dimensional lattice. In the lock step model, at each time step all of the walkers move one step in any of the allowed directions, such that at no time any two ra...

Producers of fresh fruits and vegetables face increasing production costs and international market competition. Growers who can offer high-quality watermelons [Citrullus lanatus (Thumb.) Matsum. & Nakai] that are also highly nutritious will have better market opportunities. To accomplish that, germplasm must be identified that has enhanced phytonutrient levels. Surprisingly, there is little inf...
