Occurring as a direct effect of climate, the
grapevine’s growth can be described by its phenological
events. Understanding the phenology of a given plant
system is important in determining the ability of a
region to produce a crop within the confines of its
climatic regime [6]. From a husbandry viewpoint,
knowledge of a plant’s growth stages is advantageous
as cultural and chemical practices can be applied at
optimum times in a plant’s annual growth cycle. Additionally,
information regarding growth stages can be
useful in estimating crop yields.
