Effects of water stress on vegetative growth and ‘merlot’ grapevine yield in a semi-arid mediterranean climate

Water stress is considered to be the most influential type of abiotic stress to which plants may be exposed. In grapevines (Vitis vinifera L.), it is a common practice to keep plants under water stress at different stages of the season with the aim of reducing yield and improving the composition of...
