In order to exploit remote sensing data operationally for precision agriculture applications, efficient and automated methods are required for the accurate detection of vegetation, crops and different crop varieties. To this end, we have designed, developed and evaluated an object-based classification framework towards the detection of vineyards, the vine canopy extraction and the vine variety ...

In this paper we propose a vine copula based Monte Carlo simulation model for estimating Portfolio Value at Risk. The vine copula model is introduced to analyze the complex dependence structure of different regional markets in the typical financial markets. Then we construct the vine copula based Portfolio Value at Risk model, taking into account the identified high dimensional dependence struc...

Professor Hume was right: rootstocks are critical and much is still to be learned. Rootstocks and scions are the foundation of many tree fruit industries of the world. Together, those components establish profitability, but it can be argued that the rootstock is the critical component; otherwise, scions would be grown on their own roots everywhere. There is no precedent for the failure of a cit...

Xylella fastidiosa (Xf) is the causative agent of Pierce’s Disease (PD). Collectively, a team of researchers (Lindow, Dandekar, Labavitch/Powell and Gilchrist) has identified or constructed and advanced the evaluation of five (Table 1) novel genes (DNA constructs) that, when engineered into grapevines, suppress symptoms of PD by reducing the titer of Xf in the plant, reducing its systemic sprea...

The Iberian viticultural regions are convened according to the Denomination of Origin (DO) and present different climates, soils, topography and management practices. All these elements influence the vegetative growth of different varieties throughout the peninsula, and are tied to grape quality and wine type. In the current study, an integrated analysis of climate, soil, topography and vegetat...

In Aas et al. (2009) and Aas and Berg (2009), it is shown that vine copulas constructed from bivariate t-copulas can provide better fits to multivariate financial asset return data. Several published articles indicate that for several assets there might be stronger tail dependence of returns in the joint lower tail than upper tail. We use vine copula models with appropriate choices of bivariate...

Natural infection of Cucumber mosaic virus (CMV) in Indian long pepper (Piper longum L.) and betel vine (Piper betle L.) was detected by reverse transcription polymerase chain reaction (RT-PCR). The coat protein gene sequences of CMV infecting these hosts were amplified. The resulting amplicons were cloned and sequenced. In both the cases coat protein gene consisted of 657 nucleotides, potentia...

INTRODUCTION Collectively, a team of researchers (Lindow, Dandekar, and Gilchrist) identified, constructed and advanced to field evaluation five novel DNA constructs (Table 1) that, when engineered into grapevines, suppress symptoms of Pierce’s Disease (PD) by a) reducing the titer of Xylella fastidiosa (Xf) in the plant, b) reducing systemic spread of the bacteria or c) blocking Xf’s ability t...

To evaluate the role of root-synthesized ABA in regulating growth and stomatal behaviour under well-watered conditions, isogenic wild-type (WT) and ABA-deficient flacca (flc) tomato (Solanum lycopersicum) were reciprocally and self-grafted just below the cotyledonary node. Since flc scions had lower leaf water potentials due to higher transpiration rates, a subset of all graft combinations was ...

"Lane Late" sweet orange grafted on six different citrus rootstocks and grown in the Guadalquivir valley (Seville, Spain) were picked at different ripening stages in two consecutive seasons to characterize their antioxidant activity (free radicals scavenging activity, reducing power and lipid peroxidation inhibition) and quantify their main antioxidant compounds (vitamin E and vitamin C). Linea...
