“…In a study on common bean responses to aluminum toxicity, Toth and Grusak [5] concluded that genotypes have the ability to respond differently to Al stress. However, for observations of this differential response, it is necessary to use adequate evaluation methods.…”

“…Studies evaluating dozens of common bean genotypes from different regions and diversity centers in nutrient solution also reported a great variability in Al-toxicity responses, with the identification of Al-tolerant and -sensitive genotypes [5,12,13]. According to Blair, López-Marín, and Rao [12], genotypes from the Andean diversity center tend to be more tolerant to Al toxicity, contrary to the results of this study, which indicated that genotypes of the black group (Mesoamerican) were most Al-tolerant.…”

“…Consequently, several adverse environmental conditions interfere in the cultivation of the crop. Aluminum (Al) toxicity is one of the most limiting factors to plant development, especially in acid soils [5]. Approximately one-third of the common bean-producing areas in Brazil are located in regions with sandy soil, low fertility, and high acidity and Al concentration, negatively affecting the plant development and causing yield losses [6][7][8][9].…”

Response of Common Bean Cultivars and Lines to Aluminum Toxicity

The soils in the common bean-producing regions (Phaseolus vulgaris L.) of Brazil are usually acid and conta\y66\yin toxic levels of aluminum (Al) for plants. This ion causes yield losses by inhibiting root cell expansion, thus reducing water and nutrient uptake. This study investigates the optimal Al concentration for the screening of genotypes in hydroponics cultivation and tries to identify cultivars and lines for cultivation in Al-toxic soils. The study consisted of two series of experiments. In the first one, four cultivars were evaluated at five Al concentrations (0, 2.5, 5, 7.5 and 10 ppm) and in the second, four independent tests were carried out (1-carioca, 2-black, 3-red, and 4-white), each with seven genotypes and two Al concentrations (0 and 4 ppm). The optimized concentration of Al in the first stage was 4 ppm, which allowed the early identification of genotypes with less affected development under Al toxicity in the second stage. The common bean cultivars IPR Quero-Quero (carioca group), BRS Esplendor (black group), KID 44 (red group), and WLine 5 (white group) may be indicated for cultivation under Al toxicity.

“…Under extreme drought stress when the stomatal resistance just around 0.1 mol H 2 O m −2 s −1 , poor performance of photosystem II (F v /F m ) and downregulated activities of CO 2 assimilating enzymes such as Rubisco become the dominant limitations to reduced photosynthesis [63]. The optimal photochemical activity (F v /F m ) values were sensitive for the investigated two environmental factors, and genotype differences were established in tolerance [64]. Chl-fl parameter's sensitivity for detecting nitrogen deficiency is different, but some of them are really applicable for describing nitrogen lack [65].…”

Global Wheat Production

With the projection of the Earth's population reaching eight billion in coming years and nine billion by 2050 which means increasing demand for food. Wheat (Triticum aestivum L.) is the main important and strategic cereal crop for feeding the majority of world's populations. Scientific forecasts predict that wheat production in the future will be affected by climate change and will decrease on the global level. To reduce these risks, the impact of climate change mitigation strategies and management systems for crop adaptation to climate change conditions should be considered. Demand for increases in food production will have to occur on less available arable land, which can only be accomplished by intensifying production. Chemical fertilisers are responsible for 40-60% of the world's food production. Because nonlegume plants generally require 20-50 g of nitrogen to produce 1 kg dry biomass, the natural supply of soil nitrogen usually restricts plants yield in most agricultural cropping system. The goal of ecological intensification is to increase yield per unit of land, intensify production, while meeting acceptable standards of environmental quality. This chapter discusses some aspects of connection between nitrogen supply and different abiotic conditions.

“…The number of plants per unit area is one of the most important yield components in plant production (Ma et al, 2014;Masarirambi et al, 2012;Pepó and Murányi, 2014;Varga et al, 2015;Li et al, 2017;Varga et al, 2017;Vinze, 2017). According to Balodis and Gaile (2016) plant population in relation to the sowing rate particularly affects the number of pods per plant and seed number per pod.…”

The aim of this study was to analyze the yield components of winter oilseed rape depending on the plant population in 2017/2018 growing season. Three plant populatios were considered in the study: 20, 40 and 60 plants m -2 . At harvest several yield components were determined: plant height (cm), plant mass (g), height of the first fertile branch (cm), number of fertile lateral branches, number of pods per plant, length of the pod (cm), number of seeds per pod, mass of seeds per pod (g), number of seeds per plant, 1000 grain mass (g) and yield of seeds per plant (g). At the plant population of 40 plants m -2 the plants were the highest (153.4 cm), with the highest plant mass (295.3 g) and the number of lateral fertile branches (5.6 branches per plant). Furthermore, the plants from 40 plants m -2 had the highest number of pods per plant (716 pieces), the longest pods (6.5 cm) with the largest number of seeds per pod (21.0) and the number of seeds per plant (15 036 seeds). The highest and significant correlation coeficient was found between number of pods per plant and plant mass (r=0.890***) and than between the number of lateral branches and number of pods per plant (r=0.850***). Linear regression showed that for every centimeter increment of pod length the number of seeds increase for 4.8 seeds at 20 and 40 plants m -2 and for 5.5 seeds per pod at 60 plants m -2 . Furthermore, regression analysis showed that for every centimeter pod length increment the seeds mass per pod increase on average of all plant population for 0.02 g.
