Southern Greece

In warm regions, such as in southern Greece, the climate change can lead to prolonged dormancy as well as to problems in bud dormancy (delay in breaking time, reduce the rate of budbreak, intensity of the phenomenon of acrotony, grapevine bud fall, disorders in bloom with intense blossom dropping, etc.), with a significant impact on the production of the vines. In these areas, it is necessary to apply chemical substances in order to break the dormancy and advance budbreak, especially when it comes to new table grape varieties, most of which are seedless. Another phenomenon which is observed on grapevines and is directly associated with budbreak is acrotony, where the apical buds of the cane break first compared to the middle and basal ones. Acrotony can constitute a problem because it can cause irregular grape ripening, different timing of various activities in the vineyard, which brings about higher cultivation costs. In this research, a new method to measure and evaluate the acrotony and its intensity on the latent buds of grapevine canes was described. The results of two chemical substances applied on table grape variety ‘Prime’ in order to advance budbreak were presented.   ********* In press - Online First.

Reducing Energy

The primary imperative of the sustainable development of the wine sector is to obtain organic pro-ducts, with low consumption of resources, in conditions of increased economic efficiency and the use of tec-hnological links that contribute to reducing energy consumption and protecting the environment. As a result of crossing Vitis vinifera L. with Muscadinia rotundifolia Michx. interspecific vine genotypes have been obtai-ned and identified that can be multiplied by pruning, without grafting, thus obtaining rhizogenic propagating material that contributes to reducing the costs of setting up vineyards. They were approved as table grape vari-eties: "Malena", "Nistreana" and "Algumax" and grape varieties for fresh consumption and processing: "Au-gustina", "Alexandrina" and "Amethyst". By creating plantations, it will contribute to the extension of the area to the northern limit of vine cultivation and obtaining products derived from the "organic" category.

Grape Varieties

Grape (Vitis vinifera L.) is globally cultivated as commercial fruit crop usually used for fruit purpose or industrial product. The objective of the current review is to review and identify the research gap on the effect of different growth media and vitrification on shooting and rooting performance of grape. Factors affecting rooting of grape cuttings can be internal or external factors. Currently, grapevines are very sensitive to disease in the conventional method of propagation. Even if tissue culture is recommended for healthy propagation of the grape varieties, still factors affecting the growth of the plant verifications were reported. This, review paper progressively revised for the existing factors and possible solutions during in vitro propagation of grapevines. Int. J. Agril. Res. Innov. Tech. 10(1): 1-5, June 2020
