Stage 1

Sugar concentrations were analyzed in grapevine (Vitis vinifera) buds at three different phenological stages (stage 1, dormant bud; stage 2, woolly bud; stage 5, green tip) and were submitted, under controlled conditions, to negative temperatures corresponding to the intracellular liquid crystallization points. In absence of any treatment, starch concentration diminished according to the phenological evolution, indicating its utilization during bud breaking. Starch and raffinose accumulated when controlled cooling was applied, except for stage 1 buds collected on March 6, 1993. Similarly, saccharose concentrations were reduced in bud complexes after temperature reductions. Fructose and glucose concentrations seemed to be less sensitive to thermal variations. The accumulation of starch observed at the end of a cold treatment could be partly explained by the inhibition of amylase activity under cold conditions.

Tissue Homogenates

Cell walls have been isolated from the mesocarp of mature grape (Vitis vinifera L.) berries. Tissue homogenates were suspended in 80% (v/v) ethanol to minimise the loss of water-soluble wall components and wet-sieved on nylon mesh to remove cytoplasmic material. The cell wall fragments retained on the sieve were subsequently treated with buffered phenol at pH 7.0, to inactivate any wall-bound enzymes and to dislodge small amounts of cytoplasmic proteins that adhered to the walls. Finally, the wall preparation was washed with chloroform/methanol (1:1, v/v) to remove lipids and dried by solvent exchange. Scanning electron microscopy showed that the wall preparation was essentially free of vascular tissue and adventitious protein of cytoplasmic origin. Compositional analysis showed that the walls consisted of approximately 90% by weight of polysaccharide and less than 10% protein. The protein component of the walls was shown to be rich in arginine and hydroxyproline residues. Cellulose and polygalacturonans were the major constituents, and each accounted for 30-40% by weight of the polysaccharide component of the walls. Substantial varietal differences were observed in the relative abundance of these two polysaccharides. Xyloglucans constituted approximately 10% of the polysaccharide fraction and the remainder was made up of smaller amounts of mannans, heteroxylans, arabinans and galactans.

Os sistemas atmosféricos exercem um papel significativo no clima de uma região e poucos trabalhos determinaram os impactos dos sistemas atmosféricos no de­senvolvimento e na produção de videira. Os objetivos deste trabalho foram deter­minar a frequência de ocorrência dos sistemas atmosféricos durante o período da maturação à colheita da videira (Vitis vinifera L.) var. Cabernet Sauvignon para as duas regiões produtoras de Santa Catarina em diferentes safras e determinar a as­sociação entre a ocorrência dos sistemas atmosféricos e as regiões produtoras e as safras. Os sistemas atmosféricos foram identificados durante as safras de 2005/2006 à 2008/2009. Os municípios de Água Doce e Campos Novos foram escolhidos para re­presentar a região produtora 1 e os municípios de Bom Retiro e São Joaquim para re­presentar a região produtora 2. As frequências de ocorrências dos sistemas atmosfé­ricos durante o período da maturação à colheita de videira são muito semelhantes entre as regiões, somente houve diferença na frequência de ocorrência do sistema jato subtropical entre regiões. Houve uma diferença significativa da ocorrência da frequência dos sistemas atmosféricos entre safras.
