“…The HS exhibited a negative effect on all studied faba bean genotypes. The observed decrease in growth parameters (PH, Shoot FW and DW, leaf area) with increasing levels of temperature over the control may be due to the loss of turgidity and RWC (Table 2) (Kesici et al, 2013). The high level of temperature stress might be altered cell division and cell elongation resulted in reduced leaf area in all genotypes (Table 1).…”

Heat stress (HS) is the major constraint to crop productivity worldwide. The objective of the present experiment was to select the tolerant and sensitive genotype(s) on the basis of morpho-physiological and biochemical characteristics of ten Vicia faba genotypes. These genotypes were as follows: Zafar 1, Zafar 2, Shebam 1, Makamora, Espan, Giza Blanka, Giza 3, C4, C5 and G853. The experimental work was undertaken to study the effects of different levels of temperature (control, mild, and modest) on plant height (PH) plant(-1), fresh weight (FW) and dry weight (DW) plant(-1), area leaf(-1), content of leaf relative water (RWC), proline content (Pro) and total chlorophyll (Total Chl), electrolyte leakage (EL), malondialdehyde level (MDA), hydrogen peroxide (H2O2), and activities of catalase (CAT), peroxidase (POD) and superoxide dismutase (SOD) enzymes. HS significantly affected growth performance of all genotypes. However, the magnitude of reduction in genotypes 'C5' was relatively low, possibly due to its better antioxidant activities (CAT, POD and SOD), and accumulation of Pro and Total Chl, and leaf RWC. In the study, 'C5' was noted to be the most HS tolerant and 'Espan' most HS sensitive genotypes. It was concluded that the heat-tolerant genotypes may have better osmotic adjustment and protection from free radicals by increasing the accumulation of Pro content with increased activities of antioxidant enzyme.

“…There are wider variations in strawberry cultivars in terms of their response to abiotic stress . Cultivars Elsanta, Redlans Hope and Camarosa were found to be tolerant to high temperature whereas cultivars Festival, Whitney, Fern and Cal Giant3 cultivars were sensitive . Elsanta cultivar was reported as more sensitive to salinity stress than Korona cultivar .…”

Considering the rise in global warming, identification of resistant and tolerant cultivars to stress conditions are crucial for future breeding programmes. Our results showed that some of the fruit's physical features were affected negatively by stress conditions whereas many of the biochemical features such as total anthocyanin content, total phenolic content and antioxidant activity were positively modulated. © 2017 Society of Chemical Industry.

The mechanism of tolerance to high temperatures was investigated in two strawberry (Fragaria × ananassa Duch) cultivars, 'Redlands Hope' ('R. Hope' , heat tolerant) and 'Cal. Giant 3' ('CG3' , heat sensitive). Leaves were collected from plants that were exposed to gradual heat stress and heat-shock stress separately. The contents of nonenzymatic antioxidants such as ascorbic acid (AsA) and glutathione (GSH) and the activities of enzymatic antioxidants such as ascorbate peroxidase (APX) (EC 1.11.1.11), catalase (CAT) (EC 1.11.1.6), and glutathione reductase (GR) (EC. 1.6.4.2) were measured followed by heat treatments. Additionally, proline content was determined, and heat shock proteins (HSPs) were analyzed with an immunoblotting method to investigate protein markers involved in the heat-stress tolerance of strawberry plants. The contents of AsA and GSH did not change depending on heat stress type, temperatures, or cultivars. While APX and CAT activities increased with high temperatures, GR activity was almost unchanged. The proline content of the cultivars increased in both treatments. Anti-HSP60 immunoblots revealed that a 23 kDa polypeptide was detected during the heat acclimation of strawberry cultivars. The intensity of the heat shock protein in 'R. Hope' plants was more than in 'CG3' plants. Thus, the accumulation of 23 kDa heat shock protein was correlated with the heat tolerance of the cultivars. In conclusion, strawberry leaf tissues of 'R. Hope' were found to enhance the structural stability of cellular membranes under high temperature by increasing both the activity of such enzymes as CAT and APX to activate the antioxidative systems and the expression of 23 kDa HSP.
