Test-plants for Investigations of the Physiology of Fruiting in Vitis vinifera L.

Abstract

EXPERIMENTAL work on the physiology of fruiting in woody plants is often made difficult by the large size of most mature fruit trees and vines. Many potentially useful techniques are denied the research worker, for example, growth of plants under closely controlled environmental conditions. The annual occurrence of the crop raises another difficulty because treatments must be applied and data recorded within the space of a few days or weeks, and the information obtained must suffice until the following year, as repetition of experiments in the same year is impossible.
