WineEast Grapegrowing inside and outside the tunnel on a clear day. Typically, noontime radiation is 1 watt per cm2, and this was the measurement at the site in June. In the tunnel, the incident radiation measured 0.75 watt/cm2. However, when the meter was turned off of perpendicular by just a few degrees outside, there was a dramatic drop in the incident radiation. In the tunnel, the fall off in radiation was much less. This indicated that the plastic was responsible for diffusing the incoming light and allowing the light to come into the grape canopy at many more and different angles. It did not take long after planting for differences to show up between inside and outside vines. Cabernet and Petit Verdot vines under the tunnel grew faster, and the plants were stronger with more leaves that were darker green on the inside. The canopy for outside vines was more sparse, with less intensely Visit Eastern��W��us��at�� ine March��6 ry��Expo -7, Booth��#1 2013 92 Your��Source��for��Quality��Label��Printing Award��Winning�� Custom��Pressure-Sensitive��Labels Digital������� UV��Flexo������� Letterpress������� Foil��Stamping Paper��&��Film��Stocks������� ���Ice��Bucket�����Labels�� Luminescent��Effects��on��Foil��&��Silver��Film��Stocks�� UV��Coating������� Lamination 2��Witte��Lane,��Great��Meadows,��New��Jersey����07838 Office:���� 08.637.8188�������Fax:��908.637.8189�������Cell:��908.963.7703 9 Email:��classicimpressions@embarqmail.com Website:��www.classicimpressionsco.com Trademarks Copyrights Marketing Merchandising Social Media Internet Traphagen Associations Law PLLC Intellectual Property for Business, Media, and the Arts Washington DC * (202) 223-4775 * traphagenlaw.com 62 W in e s & V i ne s M AR C H 20 13 The vines that have been housed inside a tunnel (right) are green, while those exposed to the elements were shut down by mid-October frost. green leaves. There were more shoots on the inside plants than outside. During this first year, the primary cane shoot on each vine was allowed to grow unimpeded until it reached the top of the trellis, which happened about mid-August. Shoots also budded out from this primary cane. It was a disorganized but very robust growth habit for the Cabernet and Petit Verdot. All fruit was stripped off. The Viognier was quite different. It is a testament to the vigor of the Viognier vines that they survived to grow the next year. Unfortunately, the Viognier arrived very late in 2010 and did not get planted until about July 1. As a result, they suffered severely stunted growth. Compared to the vines planted earlier, the difference between the inside and outside Viognier plants was not as significant, and the canopy in both areas was sparse. After the 2010 growing season, the Viognier produced less than one pound of pruning weight for both inside and outside plants. The Cabernet and Petit Verdot grown in the tunnel produced much higher weights: 2.1 pounds for Cabernet and 1.7 pounds for Petit Verdot, while the outside Cabernet produced 1.3 pounds and Petit Verdot 1.2 pounds. In 2011 we did not train the vines into VSP until too late in the season for adequate cane selection for the cordon. This decision led to a second year of somewhat disorganized plant growth.
