Knowledge on gene action and trait expression are important for effective breeding. The objective of this study was to determine the general combining ability (GCA), specific combining ability (SCA), maternal effects and heritability of drought tolerance, yield and yield components of candidate sweetpotato clones. Twelve genotypes selected for their high yield, dry matter content or drought tol...

Motivation: Science Gateways are web portal environments targeted for given community and dedicated to the specific scientific domain. End users require different set of tools, applications, data integration patterns to be able to satisfy special demands of different kind of scientific research approach. To let users benefit from computational resources and storage, a portal framework should su...

this study aimed to determine the effects of different shading ratio and covers on “sultana seedless” table grape quality and storability. grapevines were covered at the veraison stage with 3 shading nets (0, 35, and 75% shading), which were then replaced with covering materials including polypropylene cross-stitch (pc), life pack (lp) and mogul (mg), just before harvest. harvested grapes in al...

This paper describes the evaluation of the stability of amylose-polymer inclusion complexes under solution state in dimethyl sulfoxide (DMSO) depending on guest polymers. The three complexes were prepared by the vine-twining polymerization method using polytetrahydrofuran (PTHF), poly(ε-caprolactone) (PCL), and poly(l-lactide) (PLLA) as guest polymers. The stability investigation was conducted ...

The growth form of a vine profoundly influences its overall performance as well as many aspects of a grower's vine management. Therefore, I place the choice of a vine training system fourth in importance when establishing a new vineyard after: (1) whether or not to plant a vineyard, (2) the site for the vineyard, and (3) the variety/rootstock combination to be planted. The increasing recognitio...

BACKGROUND Quantifying terrestrial carbon (C) stocks in vineyards represents an important opportunity for estimating C sequestration in perennial cropping systems. Considering 7.2 M ha are dedicated to winegrape production globally, the potential for annual C capture and storage in this crop is of interest to mitigate greenhouse gas emissions. In this study, we used destructive sampling to meas...

Vine vigour involves the production capacity of the vine. Production capacity encompasses shoot and leaf production, as well as grape production. It would benefit grape production systems to find the correct balance between the vegetative growth (shoot and leaf “production”) and reproductive development (grape production). One could optimise vine performance by improving vine balance. Vine bala...

primary bud necrosis (pbn) in grapevine is a physiological disorder that leads to death of fruitful buds and yield loss. the aim of this study was to determine the changes in soluble sugars and starch and their relationship to the incidence of the primary bud necrosis in askari grapevine. experiment was conducted in a vineyard that the vines were 15 years old, with a head system, vines spaced 2...

Synergistic eff ect of acid and salt content plays the most important role in the marinating process. Selection of suitable procedures for preparing raw fi sh material for marination, the marinating baths compositions and storage conditions, are carried out in order to achieve a longer shelf life, to maintain quality and achieve good sensory characteristics of marinated products. In this paper ...
