In part this is because over half of Ph.D.s will teach at institutions in which teaching is as important, if not more important, than research. Departments in the non-Ivies need excellent teachers who can attract students—especially non-majors. They are looking for scholars who can not only publish, but who can teach successfully, and who can effectively advise and mentor students. Even Ivies a...

Yield, growth, and vigor of individual grape vines were correlated with nematode population densities in a series of California vineyards. In a Hanford sandy loam soil, Xiphinema americanum densities showed negative correlations with yield, growth, and vigor of vines. When vines were categorized according to vigor, X. americanurn densities had little relationship to yield of high-vigor vines, b...

The role of Grapevine Pinot gris virus (GPGV) in the etiology of grapevine leaf mottling and deformation was investigated by biological and molecular assays. A survey on different cultivars from the Trentino Region in Italy showed a widespread distribution of GPGV, which was associated with symptomatic (79%) but also with symptomless (21%) vines. Symptomatic and GPGV-infected 'Pinot gris' vines...

Potato vines are a potential feed for cattle if the vines can be preserved. The objectives of this study were primarily to study alternative methods to preserve potato vines by ensiling and determine the effects of soil contamination on ensiling. In experiment 1, vines from four potato varieties were harvested individually with a flail chopper set at three heights to vary soil contamination. Th...

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...

Copulas and vines allow us to model the distribution of multivariate random variables in a flexible way. This article introduces copulas via Sklar’s theorem, explains how pair copula constructions are built by decomposing multivariate copula densities and illustrates vine graphical representations.

Grapevine leafroll disease (GLD) is an economically important virus disease affecting wine grapes (Vitis vinifera L.), but little is known about its effect on wine chemistry and sensory composition of wines. In this study, impacts of GLD on fruit yield, berry quality and wine chemistry and sensory features were investigated in a red wine grape cultivar planted in a commercial vineyard. Own-root...

to improve commercial grapevine cultivars, it is necessary to apply such methods that by cultivation of a certain number of vines in a certain area, higher yield could be harvested. to achieve such a goal, healthy stocks with resistant to pests and diseases, high fructification and high quality of vines are needed. all these properties can be obtained successfully through clonal selection. viti...

BACKGROUND AND AIMS Covering whole vines with shade cloth is used to protect the vines from heat stress, but may have costs on vine productivity through reduced light availability. Our aim was to assess the carbon balance of vines growing with and without shade to quantify the impact of the covering. METHODOLOGY Whole vines were covered with 70 % shade cloth, and shoot leaf area and leaf, ste...
