Field trials were conducted on own-rooted ‘Cabernet Sauvignon’ grape ( Vitis vinifera L.) in a commercial vineyard (Wingara Wine Group) in the Sunraysia region of Victoria, Australia (lat. 34°13′ S, long. 142°4′ E, elevation 52 m) in 2003 and on own

Spraying Roomy Red grapes with benomyl 15 days before harvesting was effective than the control in decreasing decay percentage during 77 days cold storage(2-3°C). On the other hand, it was of meaningless effect on shattering and bleaching.
Adding sodium bisulfite at a rate of 0.25 and 0.50 gms/skgs fruits just before storage minimized decay and shattering percentage. Simultaneously, no significant influence could be detected concerning its influence on bleaching. Sodium bisulffite reduced losses in grapes, weight as well as total soluble solids and acidity than the control and benomyl treatments. The studied parameters in grapes treated with benomyl and solium bisulfite as a pre and post-harvest treatment did not differ statistically than that of those treated with sodium bisulfite alone.

Rootstocks can offer benefits such as pest resistance, tolerance of certain soil characteristics and tolerance of salts and salinity. The objective of this study was to determine if `Cabernet Franc' grafted onto various rootstocks differed in a number of measured yield and quality variables. The plots consisted of Clone 1 `Cabernet Franc' with four different rootstocks: 1103 Paulsen, 140 Ruggeri, 3309 Couderc, and St. George. Rootstock did not have much effect on the yield or quality of fruit produced by `Cabernet Franc'. Although not significantly different, the overall yield of 3309C appears to be lower than the other rootstocks. With further data, it might be possible to identify annual climate patterns that favor one rootstock over another with respect to certain quality attributes. One particular problem with `Cabernet Franc' in Oklahoma is its tendency to overbear, thus resulting in uneven ripening.

Leaf area development and canopy structure are important characteristics affecting yield and fruit quality of grapevines. Trellising systems and wide row spacing are common viticultural practices that violate key assumptions of currently available indirect methods of leaf area determination. We have developed a protocol for using a commercially available instrument to determine leaf area index (LAI) indirectly in a trellised vineyard. From knowledge of plant spacing, leaf area per vine can be calculated as required. A derived calibration equation resulted in a near 1:1 relationship (y = 0.00 + 1.00 X; r2 = 0.998) between actual and indirectly determined LAI over a range of LAI induced by irrigation treatments. The protocol involved covering 75% of the sensor with a manufacturer-supplied field of view delimiter and masking data from the outer three (of five) concentric radiation sensors. The protocol could form the basis for a general measurement technique, but may require local calibration.

Aeration through subsurface drip irrigation (SDI) can promote plant growth and increase crop yield; however, more research is focused on annual crops, and there are few studies on perennial crops. We have studied a new type of SDI (SDI with tanks) suitable for cultivation and production of perennial fruit trees and photovoltaic aeration device in greenhouse. The results showed that aeration irrigation promoted the growth of new leaves, fine roots, and new branches of grape, regulated O2/CO2 content in rhizosphere soil, and accelerated air exchange in rhizosphere soil. This study showed that aeration irrigation did not change the structure of bacteria and fungi but significantly increased the abundance of aerobic bacteria, such as Nitrospira and Cytophagia. Moreover, it promoted the increase of Pseudomonas and Aspergillus related to phosphate solubilization, that of Bacillus related to potassium solubilization, and that of Fusarium related to organic matter (OM) decomposition. This study shows that aeration irrigation through SDI with tanks can promote grape growth, which may be related to the ability of aeration irrigation to change the gas composition of rhizosphere soil, optimize the structure of rhizosphere soil microorganism.
