| Summary: | The light and temperature come at the beginning of the climatic factors that have an impact on the development
of grapevine. Light and temperature have a direct impact on photosynthesis, respiration, assimilation, transpration, formation
of color pigments, shading, berry set, acidity, productivity, shoot growth, blooming, soluble solid accummulation and
maturation on the grapevine. Temperature is one of the most important parameters that determines whether viticulture can
be made or not in an ecology. Temperature is driving several physiological processes such as bud burst, flowering, berry set,
colorization, photosynthesis, respiration, sugar accimilation and ripening. In particular, in order to carry out maximum
photosynthesis of vine should be sufficient sunshine in the vegetation period. On condition that carbon dioxide and other
factors not be limitting, the light increases the photosynthesis up to a certain point. Not only the limited amount of the light,
but also the excess of light intensity may have an adverse impact on the development of the plant. While low light causes
poor development in the shoots, high light intensity prevents the photosynthesis as a result of chlorophyll degradation. In
the vineyards to ensure the highest level of sunshine should be attention to the selection of appropriate training systems and
canopy management. |
