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.

The challenge of quality in sulphur dioxide free wines: natural polyphenol alternatives

Sulphur dioxide (SO2) seems indispensable in winemaking because of its properties. However, a current increasing concern about its allergies effects in food product has addressed the international research efforts on its replacement. This supposes a sufficient knowledge of its properties and conditions of use. Several studies compared SO2 properties against new alternatives that are supposed to overcome SO2 disadvantages. Firstly, the state of art on SO2 wine replacements is revised, and secondly, the last promising results using natural enriched polyphenol extracts are shown.

From soil to canopy, the diversity of adaptation strategies  to abiotic constraints in grapevine

Climate change is here. One of the main consequences is an increase in the frequency and severity of abiotic stresses which mostly occur in a combined manner. Grapevine, which grows in a large diversity of pedo-climatic conditions, has presumably evolved different mechanisms to allow this widespread adaptation. Harnessing the genetic diversity in these mechanisms will be central to the future of viticulture in many traditional wine growing areas. The interactions between the scion and the rootstock through grafting add an additional level of diversity and adaptive potential to explore.
At the physiological level, these mechanisms are related to processes such as root system development and functioning (water and nutrient uptake), interactions with the soil microbiome, gas exchange regulation, hydraulic properties along the soil-plant-atmosphere continuum, reserve storage, short and long distance signaling mechanisms and plasticity for some of these traits.
