The effect of exogenous CaCl2 on photosystem I and II (PSI and PSII) activities, cyclic electron flow (CEF), and proton motive force of tomato leaves under low night temperature (LNT) was investigated. LNT stress decreased the net photosynthetic rate (Pn), effective quantum yield of PSII [Y(II)], and photochemical quenching (qP), whereas CaCl2 pretreatment improved Pn, Y(II), and qP under LNT stress. LNT stress significantly increased the non-regulatory quantum yield of energy dissipation [Y(NO)], whereas CaCl2 alleviated this increase. Exogenous Ca2+ enhanced stimulation of CEF by LNT stress. Inhibition of oxidized PQ pools caused by LNT stress was alleviated by CaCl2 pretreatment. LNT stress reduced zeaxanthin formation and ATPase activity, but CaCl2 pretreatment reversed both of these effects. LNT stress caused excess formation of a proton gradient across the thylakoid membrane, whereas CaCl2 pretreatment decreased the said factor under LNT. Thus, our results showed that photoinhibition of LNT-stressed plants could be alleviated by CaCl2 pretreatment. Our findings further revealed that this alleviation was mediated in part by improvements in carbon fixation capacity, PQ pools, linear and cyclic electron transports, xanthophyll cycles, and ATPase activity.

“…Low-temperature stress, particularly low nocturnal temperature (LNT), is a major limiting factor curtailing productivity and limiting the cultivation distribution of peanuts (Wan, 2003). Tropical and subtropical plants are generally sensitive to chilling stress due to a lack of cold acclimation (Zhu et al, 2007;Liu et al, 2013;Hajihashemi et al, 2018). Low-temperature stress often negatively influences plant growth, development and photosynthetic carbon assimilation, especially during early growth.…”

“…The frequent and intense extreme climate environments of LNT stress followed by warm sunny days are common in temperate peanut-cultivating regions globally, particularly in north China (Wan, 2003). Peanut often experiences poor growth and seedling necrosis under LNT stress, which severely reduces peanut yield and seed quality (Bagnall et al, 1988;Wan 2003,;Liu et al, 2013).…”

“…Plants of tropical or subtropical origin are often susceptible to suboptimal, but non-freezing (chilling) temperature environments (Bauer et al, 1985;Damian and Donald, 2001;Zhu et al, 2007;Liu et al, 2013). LNT stress significantly reduces leaf growth and Chl a and Chl b concentrations in grapevine, which has a negative impact on photosynthesis (Bertamini et al, 2005).…”

Peanut (Arachis hypogaea L.) is a globally important oil crop, which often experiences poor growth and seedling necrosis under low nocturnal temperatures (LNT). This study assessed the effects of supplementary calcium (Ca 2+ ) and a calmodulin inhibitor on peanut growth and photosynthetic characteristics of plants exposed to LNT, followed by recovery at a higher temperature. We monitored key growth and photosynthetic parameters in a climate-controlled chamber in pots containing soil. LNT reduced peanut growth and dry matter accumulation, enhanced leaf nonstructural carbohydrates concentrations and non-photochemical quenching, decreased the electron transport rate, increased the transmembrane proton gradient, and decreased gas exchange rates. In peanuts subjected to LNT, foliar application of Ca 2+ restored growth, dry matter production and leaf photosynthetic capacity. In particular, the foliar Ca 2+ application restored temperature-dependent photosynthesis feedback inhibition due to improved growth/ sink demand. Foliar sprays of a calmodulin inhibitor further deteriorated the effects of LNT which validated the protective role of Ca 2+ in facilitating LNT tolerance of peanuts.

“…They maintained that yield increase could be achieved by improving ventilation and light penetration for the population as far as possible [3][4][5], as well as by improving LUE (light utility efficiency) on the premise of satisfying soil, fertilizer and water. A few studies showed that tillage methods could not only improve colony structure, but also improve soil microenvironment [6].…”

Abstract-Five planting modes were designed to study photosynthetic characteristics, leaf area index and yield of peanut variety as Fu Hua 17 in order to provide theoretical basis for peanut yield increase in the sandy area. Results showed that the mode of peanuts planted for double rows in the border check with mulched drip irrigation (T1) was the best. The second was the mode with single grain planted and staggered for double rows in the bare ridge (T2). The order for the yield from the highest to the lowest for the five modes was: those planted for double rows in the border check with mulched drip irrigation (T1) > those with single grain planted and staggered for double rows in the ridge (T2) > those planted and densified in the narrower ridge (T3) > those planted for three rows in the border check (T4) > those as normally planted in the bare field (CK). Therefore, the planting mode of double rows in the border check with mulched drip irrigation (T1) and the mode of single grain planted and staggered for double rows in the bare ridge (T2) were better for the sandy area.
