Background and Aims The aim of this research was to examine the effect sustained regulated deficit irrigation regimes on vegetative growth, physiological aspects yield parameters field-grown Merlot grapevines. Methods Results 4-year trial (2009–2012) in a 13-year-old commercial vineyard Vitis vinifera cv. compared following treatments: three treatments two treatments. We measured leaf area index pruning mass assess we recorded stem water potential gas exchange vine status. At harvest,...
Premise of the Study The stem Vitis vinifera , a climbing vine global economic importance, is characterized by both wide and narrow vessels high specific hydraulic conductivity. While effect drought stress has been studied in 1‐ 2‐yr‐old stems, there are few data documenting effects on anatomical structure mature, woody near base vine. Here we describe mature wood responses to two irrigation regimes anatomy conductivity Merlot vines. Methods For 4 years was applied constantly at low, medium,...
Daily or weekly irrigation monitoring conducted per sub-field management zone is an important factor in vine decision-making. The objective to determine the crop coefficient (Kc) and leaf area index (LAI). Since 1990s, optic satellite imagery has been utilized for this purpose, yet cloud-cover, as well desire increase temporal resolution, raise need integrate more sources. Sentinel-1 (a C-band synthetic aperture radar—SAR) can solve both issues, but its accuracy LAI Kc mapping needs be...
Background and Aims The effect of the timing initiation irrigation during growing season on Vitis vinifera L. Cabernet Sauvignon vines was investigated 5 successive years. Methods Results Five thresholds based measurement midday stem water potential (Ψ s) were examined: at Budburst, −0.6 MPa, −0.8 −1.0 MPa − 1.2 MPa. Midday Ψ s, gas exchange parameters [stomatal conductance (g net assimilation rate (A n)] leaf area index (LAI) measured weekly. At harvest, 12 per replicate (48 treatment)...
‘Malbec’ grapevines commonly have high yield, thus intermittently negatively affecting wine quality parameters. Here, we describe the use of late shoot pruning (LSP) practice applied for improvement. We examined effect timing LSP on vines grown in Mediterranean conditions during three consecutive seasons (2016–2018) Israel. The treatment applications (applied one, two and weeks after bud break) were compared with cluster-thinned, winter-pruned (WP + T) standard winter (WP). postponed break...
In semi-arid areas, vineyards grown for winemaking are usually mildly irrigated by drip irrigation systems in a manner maintaining drought stress. This practice ensures the proper development of vegetative and reproductive organs on one hand, other, high-quality grapes which can be hampered overly abundant water application. previous work, we have developed demonstrated an model suitable grape production areas. Here, tackle question initiation dates-should wait vines to develop stress before...
Perennial plants perpetually adapt to environmental changes in complex and yet insufficiently understood manner. We aimed separate the intra-seasonal temperature effects on structure function from perennial annual water stress effects. This study focused grapevine (Vitis vinifera L. 'Cabernet Sauvignon') petioles, which being a continuously produced organ, represent current status of plant. Field-grown mature subjected multi-annual irrigation treatments (severe stress, mild non-stressed)...
Abstract Vitis vinifera is a climbing vine with wide vessels and high hydraulic conductivity. There lack of data on the anatomical structure mature stem, most current knowledge based first-year shoots. Moreover, effect drought stress has been partly reported in shoots but not stems. In study two irrigation approaches were applied Merlot vines: constant (low, medium irrigation) dynamic (early/late season water deficit). The following parameters measured: trunk diameter, annual ring width...
