The effect of ecological conditions on the germination of pollen, fecundation and yield of some grapevine cultivars in Skopje region, Republic of Macedonia

Abstract

The ecological conditions (climatic factors and soil) during the whole year, and especially before flowering and during the time of flowering, have a great influence on the functional ability of pollen, the pollination, the fecundation and the yielding potential of the cultivars of grapevine.
During the period of time 2003-2005, researches have been conducted about the percentage of germination of pollen, the percentage of self-pollination and cross-pollination and the yielding potential of certain cultivars of grapevine in R. Macedonia, more precisely in Skopje area of vineyards.
The following cultivars of grapevines were examined: Vranec, Dattier, Italia and two different varieties of Drenok (Drenok red and Drenok black). They had different resistance to the winter low temperatures and the spring late frosts, which had a certain influence on the fecundation.
The examined cultivars of grapevine are mainly characterized with good germination of pollen and they are with a good degree of fecundation in optimal climatic conditions, excepting the varieties of Drenok (Drenok red and Drenok bleck). The obtained results of the examined elements are of a great importance for further yield and quality of the grape of the examined cultivars.

Effect of stilbenes on malolactic fermentation performance of onoccocus oeni and lactiplantibacillus plantarum strains in wine production

Malolactic fermentation (MLF) is an important step in winemaking to improve wine quality through deacidification, increased microbial stability, and altered wine flavor. The phenolic composition of wine influences the growth and metabolism of lactic acid bacteria (lab) used for MLF.

Agronomic behavior of three grape varieties in different planting density and irrigation treatments

In the O Ribeiro Denomination of Origin, there is a winemaking tradition of growing vines under a high-density plantation framework (8,920 vines/ha) and maintaining its vegetative cycle under rainfed conditions.
Currently, viticulture is advancing to plantation frames in which the density is considered medium (5,555 vines/ha), thus allowing mechanized work to be carried out for vineyard management operations. Although, the application of irrigation applied proportionally to the needs of the vegetative cycle of the vine, is a factor that increasingly helps a good development of the vine compared to the summer period, with increasingly uncertain weather forecasts.
