Effect of timing of water deficit on fruit development and composition of Vitis vinifera cv. Shiraz / M.G. McCarthy.

Abstract

This thesis describes an irrigation experiment established on Vitis vinifera cv. Shiraz in a mature vineyard in the Australian Murray-Darling basin. It concentrates on the relationship between the timing of the water deficit and the depth of irrigation applied and the difference in berry weight between different irrigation treatments. The study includes a polynomial equation which describes the relation between growing degree days and ?p0?sBrix. A two phase linear model is used to describe the change in red-free glycosyl-glucose (G-G).
