The Mathematical Treatment of Leaf Venation: the Variation in Secondary Vein Length along the Midrib
Different plant species have different levels and locations of silicon accumulation in their tissues, and may or may not have silica bodies. Grasses usually accumulate these bodies, which may have different shapes depending on the genotype. Besides, this element can be beneficial to crops. The present study aimed to examine the forms and locations of silicon accumulation, as well as silicon con...
The main role of leaf venation is to supply water across the photosynthetic surface to keep stomata open and allow access to atmospheric CO2 despite evaporative demand. The optimal uniform delivery of water occurs when the distance between veins equals the depth of vein placement within the leaf away from the evaporative surface. As presented here, only angiosperms maintain this anatomical opti...
Abstract. Daipan BPO, Buot IE Jr., HMO. 2022. Comparative analysis of the leaf architectural characters Saurauia bontocensis Merr. and polysperma (Blanco) with application Digital Image Analysis Software. Biodiversitas 23: 3869-3875. Major confusion still exists among several authors concerning taxonomy dagwey plant. This species is economically significant to Ikalahan tribe Luzon, Philippines....
Background: Many Mexican Ternstroemia species mainly inhabit the tropical montane cloud forest. These have been misidentified in herbaria due to their morphological resemblance.
 Question: Are there foliar anatomical and micromorphological characters with diagnostic value that allow discriminating between of Ternstroemia?
 Study species: sylvatica Schltdl. & Cham., T. lineata DC. ...
STYLOSA (STY) in Antirrhinum and LEUNIG (LUG) in Arabidopsis control the spatially correct expression of homeotic functions involved in the control of floral organ identity. We show here that the sty mutant also displays alteration in leaf venation patterns and hypersensitivity towards auxin and polar auxin transport inhibitors, demonstrating that STY has a more general role in plant developmen...
Leaf hydraulic conductance (KLeaf) is a measure of the efficiency water transport through leaf, which determines physiological parameters such as stomatal conductance, photosynthesis and transpiration rates. One key anatomical structure that supports KLeaf leaf venation, could be subject to evolutionary pressure in dry environments. In this context, it useful assess these traits species from ar...
Varietal control to avoid unwanted varietal mixtures is an important objective for the nursery plant industry. In this study, we have developed and analyzed capabilities of a computer vision system based on deep learning varieties in industry evaluating its capabilities. For purpose, three datasets images were compared. The came from two almond trees (Prunus dulcis) named Soleta Pentacebas. Eac...
Leaf disease detection is the process that help users to detect of plant leafs. It not only useful for farmers but also researchers.Now a days agriculture wealth has been increased in each and every country particularly agricultural strength main rural areas. But technology hasn‟t inproved area so people over there certainly educated about disease. That causes heavy loss plants some can pass th...
The success of beetles is mainly attributed to the possibility to hide the hindwings under the sclerotised elytra. The acquisition of the transverse folding function of the hind wing is an important event in the evolutionary history of beetles. In this study, the morphological and functional variances in the hind wings of 94 leaf beetle species (Coleoptera: Chrysomelinae) is explored using geom...
