The responses of two red grape varieties, Bovale Grande (syn. Carignan) and Cannonau (syn. Grenache), to temperature and natural UV radiation were studied in a three-years field experiment conducted in Sardinia (Italy), under Mediterranean climate conditions. Vines were covered with plastic films with different transmittances to UV radiation and compared to uncovered controls. Light intensity a...

1MS. intended for publication and books, etc., intonded for miew should be snt to the Editor of &Sxzwc; Garrisn-onkHudson, N. Y. ON SOME RESEMBLANCES OF CROWNGALL TO HUMAN CANCER 1 THE disease on which I shall speak today is known in this country as crown-gall, because it has been observed most frequently on the crowns of trees and shrubs, but it is not peculiar to this situation. It occurs als...

Eutypa lata is a fungal pathogen causing severe dieback in vineyards worldwide. This fungus colonizes vines through pruning wounds, eventually causing a brown sectorial necrosis in wood as well as stunted vegetative growth. Several years may pass between infection and the expression of external symptoms, hindering the rapid evaluation of both grapevine cultivars susceptibility and E. lata varia...

Botrytis cinerea is the cause of the most common disease in the Galician and Portuguese vineyards. Knowledge of the spore levels in the atmosphere of vineyards is a tool for forecasting models of the concentration of spores in order to adjust the phytosanitary treatments to real risk infection periods. The presented study was conducted in two vineyards, one located in Cenlle (Spain) and other i...

The Amur grape (Vitis amurensis Rupr.) thrives naturally in cool climates of Northeast Asia. Resistance against the introduced pathogen Plasmopara viticola is common among wild ecotypes that were propagated from Manchuria into Chinese vineyards or collected by Soviet botanists in Siberia, and used for the introgression of resistance into wine grapes (Vitis vinifera L.). A QTL analysis revealed ...

A MIP (Major Intrinsic Protein) subfamily called Uncharacterized Intrinsic Proteins (XIP) was recently described in several fungi and eudicot plants. In this work, we cloned a XIP from grapevine, VvXIP1, and agrobacterium-mediated transformation studies in Nicotiana benthamiana revealed that the encoded aquaporin shows a preferential localization at the endoplasmic reticulum membrane. Stopped-f...

Pest and disease management in the grapevine sector has become difficult due to several instances (e.g., pathogen resistance, agrochemicals withdrawals). Therefore, viticulture switched more environmentally friendly practices. On these bases, most promising tool is use of a resistant variety grapes. Luckily, genetic genomic selection have made great steps accelerating plant breeding. In recent ...

The researches carried out followed the behavior of some cultivares vines with red grapes in ampelographic collection, over a period three years (2020-2022). During study, grape for wines budded between April 13-20, 'Mamaia' cultivar earliest, and 'Pandur' at latest. Shoot fertility recorded different values ​​depending on climatic conditions. From point view average production grapes, analyzed...

In recent years, the economic impact of grape and wine industry within Texas has significantly increased. The majority grapes grown in are produced High Plains American Viticultural Area (AVA). Vineyards this AVA subject to late spring frosts that may potentially reduce crop yields, lower fruit quality. Objectives experiment were compare growth fruitfulness shoots from primary secondary buds V....

Four-week-old French Colombard plants rooted from green cuttings were inoculated with 0, 1,000, 2,000, 4,000, or 8,000 Meloidogyne incognita second-stage juveniles and maintained at 25 C night and 30 C day. Leaf area and dry weight and the rates of photosynthesis, stomatal conductance, and internal leaf CO concentration were measured at intervals up to 59 days after inoculation. Nematode stress...
