Background and Aims. Shiraz disease (SD) is a viral associated with Grapevine virus A that causes significant yield loss in economically important grape cultivars Australia such as Merlot. Current diagnostic methods are time-consuming costly. This study evaluates an alternative methodology using visible remote sensing imagery to detect SD grapevines. Methods Results. High-resolution images were...

The objective of this article is to study the microeconomic motivations grubbing up vines by analyzing application files and a survey in department south France, Hérault, year before 2008/2009 campaign, which implements European program 175,000 hectares vines. Only one French campaign are evaluated: Hérault 2007/2008. Our originality analysis subset consisting 341 Viniflhor applications for pre...

Background and Aims Environmental effects of global warming are leading to extended ripening seasons, which may either require or allow new vineyard management techniques. An innovative double-cropping technique is proposed for temperate climate areas. Methods Results The principle was maintain the primary crop as well obtain a second, late through release dormancy auxiliary buds during current...

This chapter presents the incorporation and use of regular vines into Estimation of Distribution Algorithms for solving numerical optimization problems. Several kinds of statistical dependencies among continuous variables can be taken into account by using regular vines. This work presents a procedure for selecting the most important dependencies in EDAs by truncating regular vines. Moreover, t...

The detrimental effect of soil acidity on the performance vines can be attributed to both P deficiency and Al toxicity stresses. This study aimed investigate different agronomical techniques applied in a vineyard Nebbiolo solve problem low productivity due pH. liming, phosphorus fertilization pre-bloom shoot trimming yield bud fruitfulness was followed over period 3 years. Moreover, last year g...

WHIGHAM, D. 1984. The influence of vines on the growth of Liquidambar styraciflua L. (sweetgum). Can. J. For. Res. 14: 37-39. The effect of vines on diameter growth of Liquidambar styraciflua L. (sweetgum) in a 40-year-old abandoned field was measured by vine removal experiments. Removal of vines from the trunk, branches, and ground had a significant positive effect on growth during each of the...

Previous surveys of vineyards had indicated that Mesocriconema xenoplax was present in 85% of vineyards in western Oregon, but yields were not depressed in established vines. Microplot studies were initiated in 1997 in a Willamette Valley vineyard to determine the impact of M. xenoplax on vine establishment. Plots were infested with 0.03, 0.6, and 3.0 M. xenoplax g soil and planted with self-ro...
