“…In our investigation, the short‐term chilling stress provoked differential physiological responses in two common fig varieties, Zamorčica and Green matalon. Although cold stress is known to distort integrity of chloroplast membranes (Banerjee & Roychoudhury, 2019; Ruelland & Zachowski, 2010), duration of chilling stress in our case did not induced damage to the membrane lipids (TBARS levels, Figure 1a) compared to control suggesting competent antioxidative system in both fig varieties. It was previously reported for several species, including common fig, that developing leaves possess efficient antioxidative enzymatic system that prevented them from damage caused by environmental stress (Cai, Slot, & Fan, 2005; Jiang et al, 2005; Lepeduš et al, 2011; Mlinarić et al, 2016).…”

Common fig (Ficus carica L.) is widely cultivated Mediterranean species. Such warm‐climate species are adapted to elevated temperatures and are susceptible to chilling stress (0–12°C). However, occasional short chilling periods are common during growing season in temperate areas that can affect functionality of the plant. The aim of this work was to investigate influence of short‐term chilling stress on antioxidative response and PSII photochemistry in developing leaves of two common fig varieties: Zamorčica and Green matalon. Leaves were detached from the trees, acclimated at room temperature in dark for 16 hr and then exposed to low temperature (10°C) at low irradiation (50 μmol m−2 s−1) for 4 hr. Dark adapted leaves were considered as the control. The damage to the membranes was determined as lipid peroxidation (thiobarbituric acid reactive substances) while the antioxidative response was evaluated by determining activities of the selected antioxidative enzymes. Photosynthetic performance was analysed by measuring in vivo chlorophyll a fluorescence (ChlF) increase. Relative accumulation of the main photosynthetic proteins (D1 and Rubisco LSU) was determined, as well. Due to efficient antioxidative activity, neither of investigated variety showed damage of the membrane lipids. Both varieties revealed functional antennae and its good connectivity to their reaction centres shown as negative L and K bands as well as stable D1 protein accumulation suggesting functional electron transport through photosystem II (PSII) and efficient primary photochemistry. Blocked electron flow further than QA resulted in limitation of the Photosystem I (PSI) functionality in both varieties. Due to differential relative accumulation of D1 and Rubisco LSU proteins upon the chilling stress, Zamorčica revealed greater decrease of the main photosynthetic parameters derived from in vivo ChlF induction (PItotal, PIABS and φP0) in comparison to Green matalon. In addition, increased specific energy fluxes through PSII in Zamorčica suggested its higher susceptibility to photoinhibition caused by chilling stress in comparison to Green matalon.

“…Cold stress is the main factor that decreases productivity at high altitudes in mountainous zones worldwide (Banerjee & Roychoudhury, 2019). Plants that are not well adapted to cold can survive punctual stress but are incapable of surviving prolonged cold stress and present various signs of cold‐induced damage such as chlorosis, wither leaves or necrotic tissues.…”

“…Plants affected by these abiotic stresses have evolved several morphological, physiological, and molecular responses (Körner, 2003). Regarding physiological defensive strategies, a combination of elements allows plants to avoid and/or tolerate damages produced by these abiotic stresses (Banerjee & Roychoudhury, 2019; Germino & Smith, 2000; Marothia et al, 2020). One of the processes highly affected is photosynthesis (Gururani et al, 2015), a key biological process that determines growth and development, and ultimately the vigor of plants at every development stage.…”

“…One of the processes highly affected is photosynthesis (Gururani et al, 2015), a key biological process that determines growth and development, and ultimately the vigor of plants at every development stage. The photosynthetic machinery is likely to be affected by environmental conditions that can cause an energetic imbalance in chloroplasts leading to photoinhibition, which is the decrease of the photosynthetic activity due to an excess of absorbed light energy (Molina‐Montenegro & Cavieres, 2010; Verhoeven, 2013), causing a reduction of photosynthetic efficiency (Banerjee & Roychoudhury, 2019). More specifically, the production of singlet oxygen in chloroplasts can increase under excess light conditions and lead to photoinhibition due to the combination of high solar irradiation and cold stress, both limiting the photosynthetic electron transport and the capacity of the Calvin cycle to consume ATP and reducing power (Buchner et al, 2017).…”

“…Plants that are not well adapted to cold can survive punctual stress but are incapable of surviving prolonged cold stress and present various signs of cold‐induced damage such as chlorosis, wither leaves or necrotic tissues. Exposure to cold generates different types of damage in different plant tissues, most of them related to membrane damage of different cellular compartments (Banerjee & Roychoudhury, 2019). Cold stress changes the lipid membrane composition and triggers the production of compounds such as proline, sugars, or polyphenols, as well as the synthesis of enzymatic and nonenzymatic antioxidants.…”

High‐mountain plants must withstand high solar irradiation and low temperatures during winter. Furthermore, climate change is increasing drought events, which pose an additional threat to plants. Here, we studied the stress tolerance mechanisms at various levels of biological organization in English plantain (Plantago lanceolata L.), focusing on photoprotective and antioxidant responses. The response of populations from three different altitudes in the Eastern Pyrenees (1030, 1380, and 1660 m. a.s.l.) was compared during both autumn and winter. Results showed that plants not only suffered from photoinhibition due to very low temperatures at the highest elevation during winter, but also from mild drought stress at the lowest altitude during autumn. Individuals growing at the highest elevation showed reductions in the maximum photochemical efficiency of PSII (Fv/Fm ratio), which might be caused by the lack of an increased induction of tolerance mechanisms at the highest elevation compared to the intermediate one. Although most leaves died at the highest elevation, plants could withstand stress at the organism level by generating new leaves once the stress ceased. Drought at the lowest elevation during autumn caused mild stress with small decreases in the Fv/Fm ratio, along with an increase in abscisic acid and jasmonic acid content. This study underlines the great capacity of English plantain to adapt to high elevation by activating not only photo‐ and antioxidant protection mechanisms and adjustments in stress‐related phytohormones, but also by fully regenerating its aboveground biomass through renewed growth once the stress has ceased.

Water stress negatively impacts plant morphology and physiology by inducing metabolic oxidative stress, which leads to cellular damage. Applying nutrients and/or organic molecules, such as amino acids, may mitigate the effects of drought stress. In the present study, the effects of a protective foliar complex (PFC) on late‐harvest sugarcane (Saccharum spp L.) (dry season) were evaluated. Four field experiments were carried out in commercial areas of sugarcane production in the central‐south region of Brazil using sugarcane variety CTC4: in the fourth and second ratoons in 2019 and in the fifth and third ratoons in 2020. The treatments consisted of foliar application or no application of the PFC at the beginning of the dry period in June. The PFC was applied at a dose of 10 L ha−1 in a water volume of 100 L ha−1. PFC application increased the activities of antioxidant enzymes (superoxide dismutase, peroxidase, and catalase) in sugarcane leaves. PFC application also reduced leaf levels of malondialdehyde and hydrogen peroxide (H2O2). On average, PFC application increased sucrose accumulation by 2.26 and 1.74 Mg ha−1 in 2019 and 2020, respectively, indicating improved raw material quality. In addition, PFC application mitigated damage caused by drought, with average increases in stalk productivity of 10.7 and 7.6 Mg ha−1 in 2019 and 2020, respectively. The positive effects of PFC application on plant antioxidant enzymes enabled greater biomass accumulation and, in turn, higher energy cogeneration.
