Abstract

The consumption of cut roses (Rosa hybrida) has always ranked first in the world. However, it is vulnerable to rapid petal and leaf wilting due to leaf stomatal water loss, which seriously affects its ornamental quality and economic value. Stomatal movement, a key in plant physiological processes, is influenced by potassium and nitrate. Advancing comprehension of its physiological and molecular mechanism holds promise for preserving the freshness of cut roses. This study observed the impacts of different concentrations of KNO₃ vase treatments on stomatal opening and water loss in cut rose ‘Carola’ leaves, as well as their transcriptional responses to… More >

Abstract Drought stress has become more common in recent years as a result of climate change impacts on the production of banana crops and other fruit trees. The growth and productivity of Musa spp are severely impacted by the gradual degradation of water resources and the erratic distribution pattern of annual precipitation amount. The aim of the work includes increased drought tolerance in light of water scarcity in the world as a result of the bananas’ being gluttonous for water needs. This investigation was carried out from 2019 to 2020 to study the effect of potassium silicate on morphological growth and… More >

Abstract Fusarium dry rot is considered to be the most critical soilborne and postharvest disease that damages potato tubers worldwide when they are stored for a long time. This study was performed to demonstrate the effect of crude extract, culture filtrate, and cell suspension obtained from the bacterium Bacillus subtilis HussainT-AMU, on the net house and field. From oil-contaminated soil, through the serial dilution method, biosurfactant bacteria were isolated on nutrient agar medium. To isolate and screen the prospective biosurfactant strain, various biosurfactant screening methods were used. Standard protocols were carried out for morphological, molecular, and chemical characterization. The disease incidences… More >

Abstract

The current work was performed to know the impact of cadmium (Cd) toxicity on two different genotypes of chickpea (Cicer arietinum L.) namely Pusa-BG1053 and Pusa-BG372. Cadmium was applied in the form of cadmium chloride (CdCl₂), in varying levels, 0, 25, 50, 75, and 100 mg Cd kg^-1 soil. Plant growth as well as physiological attributes were decreased with increasing concentration of Cd. Both genotypes showed the maximum and significant reduction at the maximum dose of Cd (100 mg Cd kg^-1 soil). Results of this study proved that the genotype Pusa-BG1053 was more tolerant and showed a lower decline in… More >

Abstract Haze is mainly caused by the suspended particulate matters in the air, of which the particulate matters pollution harms leaf vegetables. In this paper, oilseed rapes at four different growing periods were investigated in a simulated particulate pollution environment. In combination of hyper-spectral technology and micro examination, the response of hyper-spectral characteristics of the leaf to particulate matters was investigated in-depth. The hyperspectral, chlorophyll content, net photosynthetic rate and stomatal conductance of leaf were obtained. The deposition and adsorption of particulate matters on the leaf were observed by Environmental Scanning Electron Microscope (ESEM). Normalized difference vegetation index (NDVI), modified red… More >

Abstract A drought event can cause entire crops to fail or yield loss. In order to study the effects of continuous drought on photosynthetic characteristics, yield, and water use efficiency (WUE) of winter wheat (Triticum aestivum L.), the winter wheat variety “Aikang 58” was selected as test material with controlling the water of the pot-planted winter wheat under a mobile rainout shelter. Based on foot planting and safe wintering, winter wheat was evaluated under different drought conditions, including light, moderate and severe drought at the jointing (B), heading (C), and filling (G) stages. The soil water content was controlled in a… More >

Abstract The particle matter, particularly the suspended particle matter (PM ≤ 2.5) in the air is not only a risk factor for human health, but also affects the survival and physiological features of plants. Plants show advantages in the adsorption of particle matter, while the factors, such as the leaf shape, leaf distribution density and leaf surface microstructure, such as grooves, folds, stomata, flocculent projections, micro-roughness, long fuzz, short pubescence, wax and secretory products, appeared to play an important role determing their absorption capacity. In this paper, the research progress on the capture or adsorption of atmospheric particles was summarized, and… More >

Abstract The leaf structure and micromorphology characterize plant species and reflex its interactions with the environment. Leaf epidermis sculptures aid high transpiration plants on light reflection. The form and distribution of epicuticular wax crystalloids are important to characterize the surface. Aiming to know the micromorphology and the ultrastructure of G. arborescens, G. pohlii and G. virgata, leaves of these Cerrado native species were collected in Brasília, Distrito Federal, Brazil, at the Olympic Center of the Universidade de Brasília and at Reserva Ecológica do Roncador. Leaves of G. globosa, an Indian native species, were also studied for comparison. Leaves were fractionated, fixed… More >

Abstract Micromorphological and anatomical differences in leaf epidermis and stem xylem of Rosa hybrida ‘Lovely Red ‘ (LR) and ‘Rouge Baiser’ (RB), commercially grown in Buenos Aires, Argentina, were examined in the lower half of the terminal leaflet of 5-foliate leaves and in the basal part of stem, respectively. Digital images obtained from SEM and a phase contrast microscope were used with this purpose. Epicuticular wax, which was present on both sides of the leaves, was more abundant in LR than in RB. Stomata were only present on the abaxial side; they were 111 and 129 per mm² in LR and… More >

Abstract The natriuretic peptides (NP) are vertebrate hormones involved in the regulation of ion and water homeostasis in the cell. In plants, natriuretic peptides (PNP) have been identified by molecular and biochemical methods. It has been suggested that PNPs, have similar functions to the PN, since they mediate (1) ion transport through the cell, (2) the opening and closing of Na⁺ and K⁺ channels through the stimulation and synthesis of a second messenger such as cGMP, and (3) the aperture of stomata. In this study, a PNPs gene was partially identified by PCR in garlic (Allium sativum L.), which was called… More >
