flowers, and
fruit. The canopy plays a key role in light energy capture via
photosynthesis, water use as regulated by
transpiration, and
microclimate of ripening grapes.
Canopy management is an important aspect of viticulture due to its effect on grape
yields, quality,
vigor
Vigor or vigour may refer to:

Vine

The vine is the main part of the grapevine, extending from the
root system in the ground up to the cordons, or arms, of the vine. When the grape is young the trunk is very
