“…The results of this study showed that the activity of antioxidant enzymes in grapevines tended to increase during cold acclimation, reaching a peak in January and February with cooler temperatures and decreasing during de-acclimation ( Figure 4 ). This is consistent with many previous studies ( Hashempour et al., 2014 ; Haghi et al., 2019 ) . ASA and GSH are also important components of the oxidative defense system, acting as antioxidant protection substances and maintaining the balance between ROS generation and scavenging by participating in the ASA-GSH cycling pathway ( Anjum et al., 2012 ).…”

“…With cold acclimation, the EL-LT50 showed a decreasing trend in the early overwintering period, demonstrating that the freezing tolerance of plants gradually increased, reaching maximum value in January. With the increase of temperature in February and March, deacclimation occurred and the freezing tolerance of plants was gradually lost, as seen in many previous studies ( Yang et al., 2015 ; Haghi et al., 2019 ).…”

Most cultivars of Vitis vinifera L. are very sensitive to cold. As an exogenous protectant, Biodegradable Liquid Film (BLF) is considered to protect winegrapes from low temperatures and dry winds for safe overwintering. This study aimed to reveal the physiological and biochemical mechanisms of BLF regulating the freezing tolerance of wine grapes. Groups of ten-year-old vines (Cabernet Sauvignon) were sprayed with BLF in November 2020 and 2021, or left untreated as a control treatment, and field plant mortality after overwintering were investigated. Branch samples were collected monthly for determination of biochemical indicators. Dormant two-year-old cuttings (Cabernet Sauvignon) were also used for the determination of relative expression levels of key genes. The results showed that the application of BLF reduced the branch semi-lethal temperature in January and February samples compared with control, and reduced the mortality of above-ground parts, branches and buds. The physiological status of shoots was greatly affected by the climatic conditions of the year, but BLF treatment increased the levels of soluble protein and soluble sugar, and also decreased the content of superoxide anion and malondialdehyde at most sampling times. Correlation analysis showed that the differences in freezing tolerance between BLF and no treated overwintering(CK) vines were mainly related to peroxidase activity, soluble sugar, reducing sugar and starch content. Low temperature stress activated the over expression of ICE1, CBF1, and CBF3, especially for 12h. BLF treatment significantly increased the expression levels of CBF1 and CBF3 under low temperature stress. Overall, these results demonstrate that BLF treatment protects vines from freezing damage by upregulating osmo-regulatory substances and alleviating oxidative damage.

“…May was cool in that season with a period of waterlogging affecting the outcome of the Ca treatments (Supplementary Materials), especially those carried out during the bloom for improving the fruit set [51]. Ca plays a vital role in plant growth and development as well as in stress responses as an intracellular messenger [52,53]. Obviously, Ca foliar spraying improved the plant's resistance to stress during periods of unfavorable weather.…”

The foliar application of micronutrients can improve primary nutrient uptake. As a result, foliar treatments can reduce fertilizer application rates and help to maintain the natural health of soil. Here, we report on the tentative implementation of this approach in an apple orchard located in a temperate climate (JSC “Dubovoye” 52°36′57.1″ N 40°17′04.1″ E; planted in 2002 according to the 6 × 4 m or 417 trees ha–1 cultivar (cv.) Bogatyr grafted on B118 (Budagovskii 118). Manganese treatments augmented foliar nitrogen content and, in certain seasons, foliar phosphorus, whereas zinc treatments enhanced foliar potassium. Low-rate chemical fertilizers application (once in 5 years) on the background of initial high-rate organic fertilization (60 t ha–1 manure) allowed us to retain the optimal soil pH in the experimental orchard.

“…Application of abscisic acid (ABA) by foliar spraying (Rubio et al, 2019) and some plant beneficial bacteria-Burkholderia phytofirmans Strain Ps (Barka et al, 2006) were proposed for improving resistance to frost of grapevines but there are somehow expensive, hard to apply and results are not constant obtained. A late application of spray with calcium chloride looks like to enhance the cold hardiness (Haghi et al, 2019). Pruning of lateral shoots can help because they have less tolerance to cold (Kaya & Kose, 2017).…”

"The experiments took place in the village Hotarele (Giurgiu County) comprising a vineyard area of 1.5 ha, with the Muscat Ottonel variety. From batches treated with copper sulphate with a concentration of 1.5% before the fall of the leaves and 3% after the fall of the leaves, samples were taken and their evolution was constantly monitored before and after the cold season. The buds and wood viability at negative temperatures of -15, -18, -21°C and the content in reserve substances were analyzed. It was found that the vines treated with copper sulfate have a higher viability, therefore a better resistance to frost as well as biochemical characteristics - higher content of reserve substances, which support this resistance."
