The effectiveness of grapevine training with free shoot growth on modernized trellis in the Republic of Moldova

Abstract

An urgent problem in viticulture is the development of perspective technologies based on modernizing the trellis, improving the bush training system, adapted to the requirements of complex mechanization. The research was carried out on the variety Pinot blanc R7 where two pruning variants were studied comparing agrobiological indicators according to current standards adopted in viticulture. Was established that forming bushes on a high trunk, compared to low standard ones, has some advantages: possibilities to use of mechanization for caring the plantations, including mechanized pruning, reducing the need in manual work, ventilation of the crown of the bush and better lighting of the leaf apparatus reducing the risk of diseases and harmful effects of late spring frosts.
