Professor and Viticulture Extension Specialist Dr. Hellman plans and conducts Extension educational programs in viticulture in support of the Texas grape and wine industry. His program offers workshops, symposia, field days, and on-farm research demonstrations to instruct growers in improved grape management practices. He has created an award-winning website, the Texas Winegrape Network, as a comprehensive information resource for grape producers. Dr. Hellman recently launched a Viticulture Certificate program awarding continuing education units (noncredit) jointly offered by Texas Tech University and Texas Cooperative Extension. Dr. Hellman also leads the viticulture research program in efforts to better understand the interaction of grapevines with the environment, to discover improved management practices, and to address grape production constraints. Dr. Hellman's research program investigates the physiological basis
of grape variety adaptation to climate, conducts evaluations of wine
grape varieties and rootstocks, studies the distribution of Pierce's
disease in Texas using a geographic information system (GIS), and is
developing a GIS for vineyard site assessment in Texas. Recently
completed projects evaluated deficit irrigation strategies for grapevines
and investigated delay of bud break with abscisic acid. Basinger, A.R. and E.W. Hellman. 2006.
