“…Frost damage can significantly reduce yield or even be a limiting factor of grape growth in cold regions [ 46 ]. Rekika et al [ 47 ] showed a significant difference in the survival of primary grape sprouts among the cultivars. The initial sprouts of grapes were much more sensitive to cold than the second sprouts, which were less tolerant than the third sprouts.…”

Background Cold stress is an effective factor in reducing production and injuring fruit trees. Various materials, such as salicylic acid, ascorbic acid, and putrescine, are used to alleviate the damage of abiotic stress. Results The effect of different treatments of putrescine, salicylic acid, and ascorbic acid on alleviating the damage of frost stress (− 3 °C) to grapes ‘Giziluzum’ was investigated. Frost stress increased the amount of H2O2, MDA, proline, and MSI. On the other hand, it decreased the concentration of chlorophyll and carotenoids in the leaves. Putrescine, salicylic acid and ascorbic acid significantly increased the activities of catalase, guaiacol peroxidase, ascorbate peroxidase, and superoxide dismutase under frost stress. Following frost stress, the grapes treated with putrescine, salicylic acid, and ascorbic acid showed higher levels of DHA, AsA, and AsA/DHA than the untreated grapes. Our results showed that the treatment with ascorbic acid outperformed the other treatments in adjusting frost stress damages. Conclusion The use of compounds, such as ascorbic ac id, salicylic acid, and putrescine, modulates the effects of frost stress, thereby increasing the antioxidant defense system of cells, reducing its damage, and stabilizing stable cell conditions, so it can be used to reduce frost damage to different grape cultivars.

“…The most practical of these tests is to take the sections from the cane taken at the end of the dormant period and to obtain the cross sections in which the damage levels can be determined in advance. For this purpose, determination of the degree of damage by looking at the color change (browning of bud tissues) of living and dead tissues in winter buds is one of the most widely used methods (Odneal, 1984;Rekika et al, 2004;Köse and Güleryüz, 2009). By predetermining the level of damage, it is possible to minimize the indirect losses with appropriate pruning (Küpe and Köse, 2015;Ershadi et al, 2016).…”

This study was conducted to detect cold damage in dormant buds of grapevine under vineyard (by shooting test) and laboratory (by sectioning method) conditions. In the determination of the low temperature damage, it has been investigated whether there is a difference between the method of sectioning in laboratory conditions and the real shooting level in the vineyard conditions. The study was carried out in the vineyard which was established with the Karaerik (Vitis vinifera L.) grape cultivar in the Üzümlü district of Erzincan in 2012, 2013 and 2014. Samples of one-year-old canes from the vineyard was transported to the laboratory on the same day and sections were taken to determine the damage level. Cold damage was assessed based on 1-4 bud averages. In addition, cold damage was evaluated separately in 1 st , 2 nd , 3 rd and 4 th nodes. The mortality rates of primary and secondary buds for the first 1-4 buds average were determined and the vitality rates of tertiary buds were determined in order to determine the ultimate vitality. At the second stage of study, the mortality rates (%) of primary and secondary buds and the viability rates (%) of tertiary buds were determined by counting in spring the shoots come from the primary, secondary, and tertiary buds of the first 4 buds that were left in pruning in vineyard. Secondary and tertiary buds were also considered alive if the primary buds have sprouted in vineyard. In the study that determined the level of damage of the buds, it was found that the difference between the sectioning method and the shooting test was 7.9% in primary buds, 14.56% in secondary buds, and 0.1% in tertiary buds. The mortality rates of primary buds and the viability rates of tertiary buds were found statistically insignificant differences between the methods, however the mortality rates of the secondary buds were found statistically significant differences between the methods.
