“…Plants act in response to different abiotic stresses by shifting and changing concentration of metabolite related to different biochemical pathways so that they can acclimatize to unfavorable physiological changes (Kumar et al, 2012). Heat stress produces a significant reduction in fresh weight and RWC in aerial parts of plants (Rodríguez et al, 2015). In this study, FW and RWC gradually reduced with an increase in temperature in all four wheat cultivars and heat susceptibility index was calculated using these two parameters.…”

The aim of this study is to understand the effect of elevated temperature on wheat seedlings of four cultivars, gayetri (GY), gandhari (GN), kedar (KD), PBW343 in terms of tolerance/susceptibility, along with antioxidative and biochemical responses. For this, seedlings of four cultivars were exposed to different temperatures ranging from 25°C to 40°C for 6 h. According to heat susceptibility index calculated, GN was found to be heat tolerant, PBW343 heat sensitive, and the other two, GY and KD moderately tolerant. Exposure to high temperature led to a gradual increase in membrane lipid peroxidation and hydrogen peroxide accumulation. H 2 O 2 and malonaldehyde accumulated to much higher amount in leaf tissues of PBW343 and GY than GN and KD. Among antioxidative enzymes, catalase, glutathione reductase, and ascorbate peroxidase activity initially increased at 35°C, followed by reduced activity under heat stress in all cultivars. However, peroxidase activity continued to increase under heat stress. Total chlorophyll and non-enzymatic antioxidant carotenoids, initially increased up to 30°C, following which there was a gradual decrease in these components. Compatible osmolytes -proline and total sugar level within cellular compartments were enhanced up to 35°C. Results suggested that wheat can endure heatinduced oxidative stress up to the certain period, manifested by elevation of non-enzymatic antioxidants and osmoprotectants, as well as upregulation of antioxidative enzymes.

“…Lettuce is a cool season crop with a preferred temperature range of 7-24 • C. Inflorescence initiation is encouraged by exposure to high temperatures and photoperiods of ≥13 h [23]. Producing lettuce above these thresholds affects plasma membrane fluidity, microtubules and microfilaments, and the photosynthetic apparatus [24]. This causes an intracellular signal cascade that ultimately reduces plant yield and quality.…”

Effects of Elevated Temperature and Potassium on Biomass and Quality of Dark Red ‘Lollo Rosso’ Lettuce

Abstract:Lettuce is an economically important crop for small and medium-sized growers. When grown in adverse environmental conditions, lettuce is vulnerable to a deterioration of yield and quality. Research concerning the impact of elevated potassium (K) levels on leafy vegetables, such as lettuce, is lacking. Therefore, seeds of dark-red 'Lollo' lettuce were germinated under greenhouse conditions at 25/20 • C (day/night). Plants were transferred into 11-L containers and placed into growth chambers at 25 and 33 • C. Plants were grown with K treatments of 117.3 (control), 234.6 (2×), 469.2 (4×), and 4) 938.4 (8×) mg·L −1 . Increasing K treatments resulted in a negative quadratic response on lettuce dry mass and generated 14% more leaf calcium at 234.6 mg·L −1 . An increase in temperature from 25 to 33 • C increased leaf dry matter and biomass by 40% and 43%, respectively. Leaf water content increased by 3% as temperature increased. Plants grown at 33 • C had greater quercetin glycosides compared to plants grown at 25 • C. The results from this study suggest that temperature is a stronger regulatory factor than increasing K in the determination of lettuce yield and quality. Increasing K concentration to 234.6 mg·L −1 results in greater concentrations of leaf minerals without compromising plant yield.

“…Information on the photosynthetic aspects of brassicas, even as monocrops, is scarce. Important among the related works is that of Rodriguez et al (2015), who found stomatal conductance (gs) varying from 0.2 to 0.8 mol H 2 O m -2 s -1 in kale plants grown under temperatures of 12°C and 32°C respectively. For canola (B. napus L.), Jensen et al (1996) observed an average photosynthetic rate of 29 µmol CO 2 m -2 s -1 , stomatal conductance of between 1 and 1.5 mol H 2 O m -2 s -1 1, and Ci/Ca of 0.82 in plants subjected to a temperature of 22°C.…”

“…Kale is a sturdy crop that adapts well to different environmental conditions (Vilar et al, 2008). It is also responsive to management techniques, and can be grown under various levels of technology and cropping systems, with its own differing response mechanisms to environmental variables, even when under conditions of stress (Rodriguez et al, 2015). Among the systems for growing vegetables, intercropping is an alternative production system based on such ecological principles as diversity, where two or more species are planted together in a given area (Willey, 1979;Albuquerque et al, 2012).…”

The effectiveness of intercropping depends on the complementarity or the adaptive capacity of species during the period of coexistence. Kale is a plant that displays differing responses to environmental factors, and may therefore display different behaviour when grown with other species. The aim of this study was to analyse the physiological behaviour and competitive ability of kale when intercropped with the Welsh onion, coriander, basil and parsley. The experiment was carried out under field conditions, in a randomised block design with nine treatments and five replications. The following were evaluated: net photosynthesis, stomatal conductance, CO 2 concentration of the sub-stomatal chamber, transpiration rate, ratio between the CO 2 concentration of the substomatal chamber and the CO 2 concentration of the environment, instantaneous carboxylation efficiency, aggressivity index, and the competitive and compensation ratios. The kale plants intercropped with coriander displayed values for net photosynthesis (A) and instantaneous carboxylation efficiency (A/Ci) of 18.75 µmol CO 2 m -2 s -1 and 0.060 respectively, the lowest values for all the treatments under evaluation. The kale displayed less competitive ability. The more aggressive crops were the Welsh onion (2.25) and coriander (2.08). The parsley displayed the lowest competitive effect, having no effect on yield in the kale. The conclusion is that the coriander was prejudicial to the photosynthetic performance of the kale. The intercropping system with parsley was the most advantageous, due to the balance seen in interference between species for productive resources.
