EFFECT OF INTERACTION BETWEEN MOISTER TENSION, MAGNESIUM AND SOIL TEXTURE ON SOME ANATOMICAL PROPERTIES OF CORN. (ZEA MAYS L .) [PDF]

مجلة جامعة الانبار للعلوم الصرفة, 2014
A Factorial experiment has been carried out on the basis of Random Complete Block Design (RCBD) with three replicates for each treatment. Flowerpots with a capacity of (8 kg ) of soil have been prepared and filled with dry soil that was sifted using 2 ...

Does size matter? Atmospheric CO2 may be a stronger driver of stomatal closing rate than stomatal size in taxa that diversified under low CO2.

Frontiers in Plant Science, 2016
(1) One strategy for plants to optimise stomatal function is to open and close their stomata quickly in response to environmental signals. It is generally assumed that small stomata can alter aperture faster than large stomata.

A Bespoke Programmable Interpenetrating Elastomer Network Composite Laryngeal Stent for Expedited Paediatric Laryngotracheal Reconstruction

Advanced Functional Materials, EarlyView.
A programmable interpenetrating double‐network architecture, created via 3D‐TIPS printing and resin infusion, synergistically combines thermoplastic and thermosetting elastomers to balance structural rigidity and surface softness—crucial for paediatric laryngeal stents.

Differences in stomatal number per unit area within the same species under different micro-environmental conditions: A working hypothesis [PDF]

Acta Amazonica, 1977
A summary of Salisbury's (1927) work on stomata is presented here. He found, basically, that the number of stomata per unit area increased under more xerophytic conditions.

Stoma‐Shell Nanoarchitecture for Enhanced Plasma Confinement Catalysis in Synthesis of Ethanol from CO2

Advanced Functional Materials, EarlyView.
High‐energy electron impact in plasma catalysis often causes excessive dissociation of active intermediates, limiting C2+ product selectivity. To address this challenge, a bio‐inspired stoma‐shell nanoarchitecture is designed to decouple electron impact from catalytic reaction zones.

Microscope image based fully automated stomata detection and pore measurement method for grapevines

Plant Methods, 2017
Background Stomatal behavior in grapevines has been identified as a good indicator of the water stress level and overall health of the plant. Microscope images are often used to analyze stomatal behavior in plants. However, most of the current approaches

Stomatal Arrangement Pattern: A New Direction to Explore Plant Adaptation and Evolution

Frontiers in Plant Science, 2021
The arrangement patterns of stomata on the leaf surface influence water loss and CO2 uptake via transportation and diffusion between stomata, the sites of photosynthesis, and vasculature.

3D‐Printed Gastrointestinal Stents: In Vivo Evaluation in a Swine Small Bowel Perforation Model

Advanced Healthcare Materials, EarlyView.
Gastrointestinal fistulae and perforations can lead to severe complications including sepsis and patient death. In this work, the efficacy of 3D‐printed gastrointestinal stents composed of poly‐lactic‐acid (PLA) was evaluated in an in vivo swine model.

Integrated Single‐Cell and Spatial Transcriptomics Reveal Cell‐Type‐Specific Immune Regulatory Networks in Maize Responding to Southern Corn Rust

Advanced Science, EarlyView.
By integrating single‐nuclei and spatial transcriptomics, this study presents a stereoscopic landscape of maize leaf to Puccinia polysora infection. Epidermal and mesophyll cells initiate primary defenses via RLPs/RLKs and jasmonic acid signaling. Cell‐cell communication analyses further reveal the underlying the dynamics of the underlying immune ...
