any planning for the future requires estimates of future conditions. it is possible to study changes over time series. in this study, changes of production and cultivated area of 17 field crops of khorasan razavi province in a 25-year period were determined with mann - kendall test, sen’s estimator slope and linear regression. analysis of the three tests showed that performance of 76.5% from yi...

Experiments were carried out to determine the potential of using the powder and essential oil from dried ground leaves of Cymbopogon citratus (lemon grass) to control storage deterioration and aflatoxin contamination of melon seeds (Colocynthis citrullus L.). Four mould species: Aspergillus flavus, A. niger, A. tamarii and Penicillium citrinum were inoculated in the form of conidia suspension (...

BACKGROUND The genus Cucumis contains two species of important vegetable crops, C. sativus, cucumber, and C. melo, melon. Melon has iconographical and textual records from lands of the Mediterranean Basin dating back to antiquity, but cucumber does not. The goal of this study was to obtain an improved understanding of the history of these crops in the Occident. Medieval images purportedly of Cu...

Behaviors of Eretmocerus sp. nr. californicus females attacking Bemisia argentifolii Bellows & Perring infesting cotton, Gossypium hirsutum L., and melon, Cucumis melo L., were quantified. Adult female behaviors were described and quantified for Eret. sp. nr. californicus to establish a behavioral time budget analysis. Females readily searched for host whitefly nymphs on cotton leaves with walk...

Phenylpropanoids and flavonoids belong to a large group of secondary metabolites, and are considered to have antioxidant activity, which protects the cells against biotic and abiotic stresses. However, the accumulation of phenylpropanoids and flavonoids in bitter melon has rarely been studied. Here, we identify ten putative phenylpropanoid and flavonoid biosynthetic genes in bitter melon. Most ...

The melon (Cucumis melo) genome and genetic maps with hundreds to thousands of single nucleotide polymorphism markers were recently released. However, a high-resolution genetic map was lacking. Gummy stem blight (Gsb) is a destructive disease responsible for considerable economic losses during melon production. We herein describe the development of an ultra-dense genetic map consisting of 12,93...

Background: Worldwidely cultivated, melon is commercially an important fruit crop, as it is in Iran. Objectives: Establishment of an efficient in vitro plant regeneration system plays a pivotal role in the plant transformation, hence, the importance of regeneration protocol for Iranian melon (Cucumis melo L. var. Gorgab) has encouraged us to work on in vitro melon regeneration. Material and Me...

The major challenge for the tomato farmers is getting a fair price at the market price given that there are many actors involved in the tomato value chain. Given this situation, this project's goal was to improve communication pathways in dissemination of agricultural market information in tomato value chains in Iringa and Dodoma Regions in Tanzania. The specific objectives were to: identify an...
