In recent years, technological innovations have allowed significant advances in the diagnosis of seed quality. Seeds with superior physiological quality are those highest level maturity and integration rapid precise methods to separate them contributes better performance field. Autofluorescence-spectral imaging is an innovative technique based on fluorescence signals from fluorophores present tissues, which biological implications for Thus, through this technique, it would be possible classify seeds different maturation stages. To test this, we produced plants a commercial cultivar (MG/BR 46 “Conquista”) collected at five reproductive (R) stages: R7.1 (beginning maturity), R7.2 (mass R7.3 (seed disconnected mother plant), R8 (harvest point), R9 (final maturity). Autofluorescence were extracted images captured excitation/emission combinations. parallel, investigated physical parameters, germination, vigor dynamics pigments verify accuracy predicting stages autofluorescence-spectral imaging, created machine learning models three algorithms: (i) random forest, (ii) neural network, (iii) support vector machine. Here, reported unprecedented use soybean seeds, especially using combination chlorophyll (660/700 nm) b (405/600 nm). Taken together, algorithms showed high segmenting maturation. summary, our results demonstrated that their identity wavelengths chlorophylls, allows as marker

Drought stress poorly impacts many morphological and physio-biochemical processes in plants. Pea (Pisum sativum L.) plants are highly nutritious crops destined for human consumption; however, their productivity is threatened under drought stress. Thiamine (vitamin B1) well-known essential micronutrient, acting as a cofactor key metabolic processes. Therefore, this study was designed to examine the protective effect of foliar application thiamine (0, 250, 500 ppm) on two varieties pea Here, we conducted pot experiment at Government College Women University, Faisalabad, investigate traits (sarsabz metior) grown treatment. applied after germination period 1 month. Results showed that root fresh dry weight, shoot number pods, leaf area, total soluble sugars, phenolics, protein contents, catalase, peroxidase, mineral ions were reduced against However, (both 250 overcome also enhances these parameters, significantly increases antioxidant activities (catalase peroxidase). Moreover, performance sarsabz better control conditions than metior variety. In conclusion, exogenous enabled withstand by regulating several physiological biochemical mechanisms. agriculture, it great latent alleviate antagonistic impact through thiamine.

Summary Plant photosynthesis is highly responsive to fluctuations in environmental cues. To achieve optimal photosynthetic performance, plants must accurately regulate light absorption, maintaining a dynamic balance between energy supply and consumption the field. Understanding potential damage imbalances caused by excessive during necessitates comprehensive insight into protective role of non‐photochemical quenching (NPQ). This rapid photoprotective mechanism dissipates excess excitation as heat ubiquitous throughout plant kingdom. Previous reviews have primarily focused on regulation NPQ amplitude, often overlooking its efficiency photoprotection. review outlines significance, components, mechanisms NPQ, presenting fundamental equations that quantitatively describe both amplitude functions. I highlight methodological approaches quantify levels necessary prevent photoinactivation photoinhibition, respectively. conclude identifying key open questions regarding suggesting directions for future research.

The economically adaptable mulberry (Morus alba L.) has a long history of grafting in China, yet the physiological mechanisms and advantages drought tolerance remain unexplored. In our study, we investigated responses self-rooted 2X (diploid), 3X (triploid), 4X (tetraploid) plants, as well polyploid plants grafted onto diploid seedling rootstocks (2X/2X, 3X/2X, 4X/2X) under stress. We found that exhibited most severe phenotypic damage, lowest water retention, photosynthetic capacity, least effective osmotic stress adjustment compared to tetraploid triploid plants. However, showed mitigation drought-induced with higher relative content improved soil retention. Grafted also photosystem response through elevated potential, closed stomatal aperture, faster recovery chlorophyll biosynthesis leaves. Additionally, altered protective compound levels, including starch, soluble sugar, proline content, thereby enhancing resistance. Absolute quantification PCR indicated expression levels synthesis-related genes were not influenced after stress, whereas they significantly increased Consequently, findings support mulberries superior resistance Moreover, enhanced against mulberry, but tetraploid. Our study provides valuable insights for comprehensive analysis effects between stem-roots rootstocks.

Numerous works have demonstrated that cold plasma treatments constitute an effective procedure to accelerate seed germination under nonstress conditions. Evidence also exists about a positive effect of plasmas for environmental stress For barley seeds, this work studies the influence on rate and initial stages plant growth in common environments, such as drought, salinity, low-temperature As general result, it has been found was higher plasma-treated than untreated seeds. Plasma induced favorable changes radicle dimensions, which depended environment. The obtained results demonstrate affects biochemical metabolic chains seeds plants, resulting concentration growing factors, faster germination, initially more robust growth, even These phenotype are accompanied by differences biomarkers photosynthetic pigments (chlorophylls b carotenoids), reactive oxygen species, and, particularly, amino acid proline leaves young with depend conditions application treatment. This supports idea that, rather increase water imbibition capacity, there clear beneficial effects seedling treatments.
