The series of lectures on the effect of defoliation on the grapevine and on the quality of grapes - Dobrovo
On January 14th, 2014 at 13.00 at the Vinska Klet in Dobrovo, Goriška Brda, Slovenia, Prof. Paolo Sivilotti (University of Nova Gorica, The School of Viticulture and Enology), in collaboration with the Agriculture and Forest Chamber of Slovenia, The Agriculture and Forest Institute of Nova Gorica (KGZS - Institute GO), opened the series of his lectures for the year 2014.
The lecture, a result of a decade-long research, continues the work of the VISO project theme. Its presentation follows the tasting of experimental wines at the Lanthieri Palace in Vipava in Slovenia, organized in December 2013 in order to experience wines produced in the defoliation tests conducted by the University of Nova Gorica in 2013.
" The plants produce metabolic responses in response to water stress (polyphenols), to light stress (polyphenols, thiols ) and pathogens (PR proteins)," says Prof. Sivilotti and continues: "some agronomic techniques, such as defoliation, decrease the pressure of the diseases as they improve the microclimate of the grape bunches. "
The lesson will focus on the effects of defoliation techniques on the production and quality of the grapes in pre- bloom and post- bloom period and on improving the microclimate of the grape bunches with the optimization of agronomic management and organised defense of the vineyard. The results of the tests, set up from 2006 to present, will be presented, regarding varieties of Pinot Grigio, Pinot Noir, Merlot, Friulano and Sauvignon.
The lesson of Dobrovo is a part of the 2014 program of professional training called “The Knowledge as a key element of agricultural development ", organized by Kmetijski Gozdarski Zavod Nova Gorica, Department for Agricultural Consultancy - Brda.
The first lecture was attended by 65 members and producers from the wine sector, mainly from the Slovenian Collio and Italy.
