The influence of climate on the grapevine phenology and content of sugar and total acids in the must
For the period of 10 years in the condition of Skopje vineyard area, at two regional (Vranec and Smederevka) and two international (Cabernet sauvignon and Chardonnay) grapevine cultivars, the researches are done.
The influences of temperatures sum on the duration of following phenological stages (number of days) are analyzed: from budburst to full maturity; from budburst to flowering and from veraison to full maturity. The temperature sum has a high impact on the duration of each phenological stage, especially from budburst to full maturity and from budburst to flowering. The climate has the influence on the content of sugar and total acids in the must. These parameters show grater variation at the cultivars Cabernet sauvignon and Chardonnay than cvs. Smedervka and Vranec.
