The Effect of Grape Marc and Olive Pomace Organic Wastes on Nutrition of Kalecik Karası and Narince (Vitis vinifera L.) 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

I Gene

The aim of this study was to compare the natural variability of the expression of class I chitinase gene in grapes of Vitis vinifera L. varieties as well as investigate their antimicrobial activity. Further, the effect of antimicrobial activity in chitinase expression was analyzed. Matured berries of thirteen grape varieties were used in the study—Alibernet, Dornfelder, Cabernet Sauvignon, Blaufränkisch, Sauvignon Blanc, Welschriesling, Weisser Riesling, Irsai Oliver, Pinot Blanc, Pálava, Müller-Thurgau, Grűner Veltliner, and Feteasca Regala, grown in the Small Carpathians wine region of Slovakia, Vrbové. Chitinase I gene expression was found to be similar in most of the analyzed varieties with the except of two varieties, where the expression of chitinase I was significantly higher—Pinot Blanc and Savignon Blanc. By comparing the varieties between the lowest and highest expression fold change, they were statistically different in the level of its chitinase I gene expression. Grape pomace extracts of analyzed Vitis vinifera L. were effective against Gram-positive, Gram-negative bacteria and yeasts, but a weak correlation tendency was found between chitinase I gene expression and antimicrobial activity, only against Staphylococcus aureus subsp. aureus, Candida albicans, and Candida glabrata.

Hailstorms are typically localized events, and very little is known about their effect on crops. The objective of this study was to examine the physiological and vine performance responses to natural hail, registered four weeks after full bloom, of field-grown Thompson seedless (Vitis vinifera L.) grapevines, one of the most important table grape varieties cultivated in Greece and especially in the Corinthian region in northeastern Peloponnese. Leaf gas exchange, vegetative growth, vine balance indices, cane wood reserves, yield components, and fruit chemical composition were recorded from hail-damaged vines and compared with control vines. Visibly, the extent of the hailstorm damage was great enough to injure or remove leaves as well as cause partial stem bruising and partial injury or total cracking of berries. Our results indicated that natural hail did not affect leaf photosynthesis, berry weight, total acidity, and cane wood reserves but significantly reduced the total leaf area, yield, and the total phenolics of berries at harvest. At the same time, hail-damaged vines increased the leaf area of lateral canes and presented a higher total soluble solid (TSS) accumulation, while no effect on the next year’s fertility was registered. The present work is the first attempt to enhance our understanding of the vegetative yield, berry quality, and physiological responses of grapevines to natural hail, which is an extreme and complex natural phenomenon that is likely to increase due to climate change.
