Abstract Gamma-Aminobutyric acid (GABA) accumulates in plants following exposure to heavy metals. To investigate the role of GABA cadmium (Cd) tolerance and elucidate underlying mechanisms, (0, 25 50 µM) was applied Cd-treated maize plants. Vegetative growth parameters were improved both control due application. Cd uptake translocation considerably inhibited by GABA. Antioxidant enzyme activity enhanced subjected Cd. Concurrently caused further increases catalase superoxide dismutase...

Abstract Identifying environmental factors that improve plant growth and development under nitrogen (N) constraint is essential for sustainable greenhouse production. In the present study, role of light intensity N concentrations on biomass partitioning physiology chrysanthemum was investigated. Four intensities [75, 150, 300, 600 µmol m −2 s −1 photosynthetic photon flux density (PPFD)] three (5, 10, 15 mM L ) were used. Vegetative generative traits improved by increase in PPFD...

GABA (gamma-aminobutyric acid) and melatonin are endogenous compounds that enhance plant responses to abiotic stresses. The response of Vicia faba different stressors (salinity (NaCl), poly ethylene glycol (PEG), sulfur dioxide (SO2)) was studied after priming with sole application or their co-application (GABA + melatonin). Both increased leaf area, number flowers, shoot dry fresh weight, total biomass. Plants treated GABA, melatonin, developed larger stomata wider aperture compared the...

Abstract γ-Aminobutyric acid (GABA) is a non-protein amino with multifunctional roles in dynamic plant responses. To determine the effects of exogenous GABA application (0, 25 and 50 µM) on drought response, two chickpea cultivars contrasting tolerance to water deficit were examined. Plants exposed four irrigation levels (irrigation 100, 60, 40 20% field capacity). Water decreased growth, chlorophyll content, photosynthetic efficiency. It increased electrolyte leakage lipid peroxidation...

Abstract Light quality and intensity markedly influence stomatal activity, a crucial physiological process regulating gas exchange water loss in higher plants. Stomata dynamically open close response to environmental signals, facilitating carbon dioxide uptake for photosynthesis while modulating transpirational loss. Although red blue light are well-established regulators of function, the effect green on this remains comparatively underexplored. In study, effects multiple wavelengths (430...

The legalization and expanding applications of Cannabis sativa L. demand standardized cultivation practices to ensure consistency, quality, compliance across the burgeoning cannabis industry, academia, home growers. However, historical legal status has fragmented knowledge base, leading disparities in methodologies outcomes. This manuscript introduces a pioneering cloning propagation protocol for L., developed through comprehensive synthesis current research, practical observation, agronomic...

This study offers new perspectives on the biochemical and physiological changes that occur in wheat following a gene-for-gene interaction with fungal pathogen Zymoseptoria tritici. The Z. tritici isolate IPO323, carries AvrStb6, while ΔAvrStb6#33, lacks AvrStb6. cultivar (cv.) Shafir, bears corresponding resistance gene Stb6. Inoculation of cv. Shafir these isolates results two contrasted phenotypes, offering unique opportunity to immune response caused by recognition AvrStb6 We employed...

The postharvest lighting environment is a main factor that influences quality preservation for harvested biomass. objective of this study was to evaluate changes in bioactive compounds lettuce with different storage light spectra. effects green LEDs peaks at 500 nm and 530 nm, white (400–700 nm), dark were evaluated, where intensity (10 μmol m -2 s -1 ) photoperiod (12 h per day) constant air temperature 5°C over the 14 d treatment period. Lettuce stored exhibited 1474.5% 1451.8%...

Abstract Biomass partitioning is one of the pivotal determinants crop growth management, which influenced by environmental cues. Light and CO 2 are main drivers photosynthesis biomass production in plants. In this study, effects levels: ambient 400 ppm (a[CO ]) elevated to 1,000 (e[CO different light intensities (75, 150, 300, 600 μmol·m −2 ·s −1 photosynthetic photon flux density – PPFD) were studied on growth, yield, chrysanthemum The plants grown at higher intensity had a dry weight (DW)...

Basil (Ocimum basilicum L.) is one of the important medicinal and aromatic plants. Light intensity an indispensable factor for plants due to its effect on photosynthesis physiological processes. Here, we investigated impact light intensities harvesting times green purple basil. The experiment involved subjecting three different sunlight levels 12 days: complete – 100%, 50%, 30% sunlight. In addition, scrutinize time. highest photosynthetic protective pigments were detected under full...

Basil (Ocimum basilicum L.) is one of the most important medicinal and aromatic plants. Light intensity an indispensable factor for plants due to its effect on photosynthesis physiological processes. Here, we investigated impact light intensities harvesting times green purple basil. The experiment involved subjecting three different levels sunlight 12 days: complete—100%, 50%, 30%—sunlight. In addition, evaluated harvest time during day. highest photosynthetic protective pigments were...

The root knot nematodes (RKNs) parasitizing almost all plant species. RNKs are difficult to control due their wide host range, short life cycle, and high reproduction. This study planned develop an effective environmentally safe method for managing RKNs. Different light spectra, including Red (R), Blue (B), Red:Blue (75%R:25%B) white (W) with 250 µmol.m-2.s-1 were used in separate growth chambers. In each chamber, tomato plants treated Meloidogyne javanica, Bacillus subtilis, combination,...

Zymoseptoria tritici is the causal agent of Septoria blotch (STB), one most economically destructive wheat foliar diseases. In this study, we explore physiological and molecular changes elicited in two cultivars with divergent responses (Taichung 29 = susceptible, Shafir resistant) upon infection by Z . Our aim to uncover novel insights into intricate mechanisms that govern defense against infection. quantitative histopathological study showed H 2 O accumulated resistant cultivar a higher...
