In vitro cultures of grape tissues : new possibilities to study grape berry phy...
Breia, Richard; Serôdio, J.; Gerós, H.; Cunha, AnaGrape berries suffer important morphological, biochemical and physiological changes during its development and maturation. It is known that photoassimilates translocated from leaves serve as the major source of carbon and energy to support fruit needs, but recent findings revealed that, at least in the green phase, grape berries show high photosynthetic activity especially in the exocarp. The contribution of fr...
A 2d in vivo approach to study photosynthesis in grape berry
Breia, Richard; Vieira, S.; Silva, J. Marques da; Serôdio, J.; Gerós, H.; Cunha, AnaIs argued that fruit photosynthesis serves mainly as a respiratory CO2 refixation mechanism [1] but its contribution to growth and metabolism, localization and dynamics during fruit development are poorly known. Unlike the leaves, fruit volume imposes a constraint to photosynthesis by limiting light penetration. However, the patterns of chlorophyll distribution are apparently independent of a light intensity gr...
