Foliar application of putrescine, salicylic acid, and ascorbic acid mitigates frost stress damage in Vitis vinifera cv. ‘Giziluzum’

Abstract

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.

Physiochemical Responses and Ecological Adaptations of Peach to Low-Temperature Stress: Assessing the Cold Resistance of Local Peach Varieties from Gansu, China

“…The cold resistance of peach may be closely associated with multiple parameters. For instance, MDA, the end product of membrane lipid peroxidation, serves as a marker for assessing cell membrane damage in cold-resistance evaluations [ 15 , 16 ]. Under LT stress, plants accumulate various osmoregulatory substances to enhance their osmoregulation capacity and improve cold resistance [ 17 ].…”

Exogenous Spermidine Alleviated Low-Temperature Damage by Affecting Polyamine Metabolism and Antioxidant Levels in Apples

“…In a study of grape response to drought, Zhao et al [ 23 ] found that exogenous Put could accelerate the ascorbate–glutathione (AsA-GSH) cycle and upregulate the transcription of PA synthesis genes and the accumulation of PAs, thereby improving the drought resistance of grapes. Jalili et al [ 24 ] found that the exogenous application of 5 mM Put could alleviate lipid peroxidation, increase membrane stability in grapes, and reduce frost damage in different grape varieties. However, few studies have investigated the effects of exogenous PAs on cold resistance in apples.…”

Transcriptome Analysis Reveals That Ascorbic Acid Treatment Enhances the Cold Tolerance of Tea Plants through Cell Wall Remodeling

“…Although comparable studies on various plant species have been published with similar conclusions, the potential molecular mechanisms are different. For instance, previous studies demonstrated that the exogenous application of AsA enhanced cold stress tolerance by activating various antioxidant enzyme activities such as CAT, GPX, APX and SOD [ 46 ]. Other investigations, however, have reached different explanations.…”
