“…Nevertheless, carotenoids were less affected than chlorophylls, leading to a decrease in ratio (total chlorophyll/total carotenoids) in all genotypes, as observed in maize (Holá et al, 2007). This ratio decrease resulting from a stronger reduction of energy-capture pigments could be considered a response to low capture of excessive light energy under stress conditions.…”

The objective of this work was to evaluate photoprotective mechanisms related to low positive temperatures in Coffea canephora (Conilon clones 02 and 153) and C. arabica ('Catucaí' IPR 102) genotypes, involved in cold temperature tolerance. To accomplish this, one-year-old plants were successively submitted to: temperature decrease of 0.5ºC day-1, from 25/20ºC to 13/8ºC; a three-day chilling cycle at 13/4ºC; and a recovery period of 14 days (25/20ºC). During the experiment, leaf gas exchange, chlorophyll a fluorescence and leaf photosynthetic pigment content were evaluated. Total activity of ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) and ribulose-5-phosphate kinase (Ru5PK) were quantified to measure the activity of photosynthesis key enzymes. All genotypes showed low temperature sensitivity, but displayed diverse cold impact and recovery capabilities regarding the photosynthetic-related parameters studied. Catucaí IPR 102 cultivar showed better ability to cope with cold stress than the Conilon clones, especially Conilon 02, and had full recovery of leaf gas exchange, fluorescence parameters, enzymatic activity, and higher contents of the photoprotective pigments zeaxanthin and lutein.

“…In many studies, it has been shown that chilling temperatures affected the photosynthesis negatively [10,17,35]. Kaur et al [19] reported that chlorophyll content in chickpea leaves exposed to chilling stress decreased, compared to the control.…”

“…ROS leads to chlorophyll degradation and lipid peroxidation [32]. There are reports stating that it causes a decrease in chlorophyll contents in leaves of low temperature plants, especially in plants with tropical and subtropical origin [17,18]. Lipid peroxidation in biological membranes is an important symptom of oxidative stress in plants [20].…”

In this study, the changes caused by chilling stress on some physiological parameters of pepino (Solanum muricatum Ait.) plant and the effects of ascorbic acid (100 mM) applied exogenously on these changes were examined. For this purpose, the photosynthetic pigments (chlorophyll a, chlorophyll b, total chlorophylls and carotenoids), ascorbic acid, total phenolic compounds, malondialdehyde and proline contents in leaves of pepino taken on 5 th and 10 th days were determined. As a result of chilling stress, it was found that while the photosynthetic pigments and proline contents decreased in pepino leaves, the ascorbic acid, total phenolic compounds and malondialdehyde contents increased. In plants which were subjected to pre-treatment of ascorbic acid on the 10 th day of stress, ascorbic acid and proline contents increased while a decrease was observed in malondialdehyde content, compared to stress group without pre-treated. This study may be important for explaining resistance induced by treatment of exogenous ascorbic acid in pepino exposed to chilling stress.

“…Temperatures below 12-15ºC may damage the young plants, causing chilling stress (Hola et al, 2007;Leipner, 2009). Maize plants are the most sensitive to chilling during the transitional phase from heterotrophic to autotrophic nutrition (Stamp, 1984), which usually lasts several weeks after sowing.…”

“…The performance of maize plants during both chilling stress and recovery strongly depends on hybrid tolerance (Bano et al, 2015;Sowinski et al, 2005). Many reports demonstrated significant differences in chilling tolerance among maize hybrids (Aroca et al, 2001(Aroca et al, , 2003Haldimann 1998Haldimann , 1999Hola et al, 2007). Photosynthetic performance during the chilling period and after recovery could be a good indicator for the hybrid tolerance to chilling.…”

Abstract:In the climate conditions of Bulgaria, early stages of maize plants development often go under suboptimal temperatures. Chilling stress is known to cause different physiological disturbances in young maize plants during the transition period from heterotrophic to autotrophic nutrition. However, the effect of chilling may differ among maize hybrids. Photosynthetic performance could be a good indicator for the hybrid tolerance to chilling. The aim of our study was to evaluate the tolerance of young maize plants from two hybrids -the new Bulgarian hybrid -Kneza 307 and the hybrid P9528 using as criteria the changes in their photosynthetic performance.Plants at the third leaf stage were exposed for seven days to chilling stress. At the end of the experimental period, growth, leaf lipid peroxidation, and several photosynthetic parameters were measured. We found that chilling stress reduced the fresh mass accumulation, increased lipid peroxidation, diminished net photosynthetic rate and chlorophyll content, and enhanced non-photochemical quenching of chlorophyll fluorescence. Although the responses of both hybrids were similar, some specificity were observed and discussed.UDC Classification: 581.1; DOI: http://dx
