Abstract:
Vine resistance over the winter is influenced by the maturation of the
shoots on the one hand, and the genetic resistance of cultivated plants, on the
other hand. A big problem is the intensity of extreme values of climate factors.
Although they were considered incidental in recent years they have become
common. Due the excessive heating of the air in winter, often producing strong
annealing, negative values occur leading to loss of viability buds (Dobreva et al.,
2006). Among the carbohydrates, starch is the most important reserve substance
of string, and the percentage that is in the string, the end of the growing
influence plant resistance to low temperatures in winter conditions. Starch
content values close to normal (3.6%) were recorded in most varieties analyzed,
except Fetească albă in Dealul Bujorului vineyard cultivated and grown cultivar
Riesling italian in Dealul Bujorului vineyards and Iasi, which starch content was
a maximum, showing that the enzymatic hydrolysis was less pronounced.
