Climate changes and environmental contaminants are daunting challenges that require an urgent change from current agricultural practices to sustainable agriculture. Biostimulants natural solutions adhere the principles of organic farming believed have low impacts on environment human health. Further, they may contribute reducing use chemical inputs while maintaining productivity in adverse environments. generally defined as formulated substances microorganisms showing benefits for plant growth, yield, rhizosphere function, nutrient-use efficiency, quality harvested products, or abiotic stress tolerance. These biosolutions categorized different subclasses. Several them enriched glycomolecules their oligomers. However, very few studies considered active molecules biostimulation a subclass own. Herein, we describe structure functions complex polysaccharides, glycoproteins, glycolipids relation defense biostimulation. We also discuss parallels between sugar-enhanced with introduce concept sweet glycostimulation.

This study introduces PollenQuantTom, a deep learning tool tailored for automatically analysis of RGB digital microscope imagery obtained via smartphone cameras tomato pollen grains from modified Alexander's staining. It revolutionizes grain by automating the process and applying convolutional neural networks precise classification quantification viable non-viable grains. In scenarios with 1 to 166 per image (2448x3264 pixels, 72 dpi), PollenQuantTom achieves remarkable correlation coefficient 0.992 both traits. Further evaluation through Bland Altman method highlights its reliability, mean differences 2.193 1.910 total counts. Beyond accuracy, significantly enhances efficiency, processing images 12.73-fold 80.41-fold faster than manual counting pre-cropped post-cropped images, respectively, in dataset 300 images. Expanding utility, quantifies counts flower 270 accessions, revealing significant genetic variability lowest viability (SVRDC4; = 42.50±9.98%) highest (LE404; 98.52±69.53%). Two-way ANOVA confirms consistent performance across blocks (p > 0.01). represents pioneering tool, advancing quality assessment tomatoes. Its speed, precision, reliability offer valuable support agricultural practices breeding, facilitating critical phenotypic trait evaluation.

The increasing use of photoselective nets (PNs) raises the question their influence on pollen traits. We aimed to evaluate effect PNs (yellow, pearl, and grey) ‘Matua’ ‘Tomuri’ Actinidia deliciosa cultivars. size exine were studied with a light microscopy scanning electron microscopy, fertility was analysed by viability assay in vitro germination. total soluble proteins (TSPs) sugars (TSSs) quantified colorimetric assays. molecular structure grain’s wall Raman spectroscopy. from plants under had larger width area lower germination rate. No significant changes observed exine’s microperforations. TSP TSS contents influenced cultivar (particularly pearl PN). spectra grown presented some bands that significantly shifted original position, indicating differences vibration modes molecules, but no overall at structural or organisation level found. Our study showed could several traits, PN inducing greater modifications. results also support idea cultivars affect outcome characteristics.
