In this study, S. nigra L. and ebulus (Adoxaceae) species belonging to the Sambucus genus were examined. Species of collected from northern Turkey anatomical comparisons made. Stem leaf anatomy examined by light microscopy. The plants have woody stem anatomy. druse crystals which are main characters observed in taxa. Differences found number cells vascular bundles, arrangement druze crystals, s...
Pterocephalus (Caprifoliaceae) consists of 30 species worldwide, mainly distributed in the temperate regions of the northern hemisphere, of which 14 species were reported from Iran, including five endemic ones. In this study, 35 leaf-related traits and 30 peduncle-related traits were investigated by light microscopy of 15 samples from 11 Iranian species of Ptreocephalus. Our results showed that...
the anatomical and epidermal characteristics, as well as the physiological response, of 'colombia' ecotype cape gooseberry plants treated or untreated with foliar applications of kaolin at 2 irrigation levels (well-irrigated plants vs. water-stressed plants) were evaluated. relative water content (rwc), stomatal density, and chlorophyll index were reduced under water stress. water stress increa...
The characteristics of Lycium chinense Mill and barbarum L., species, taxonomy, origin use in medicineare given. adaptation these plants the conditions Botanical Garden Tashkent, as well Namangan region, was studied. morphological anatomical structures two species genus have been morphology structure vegetative generative organs, which differ from each other leaf shape venation, are described. ...
The stem and leaf anatomical studies of Euphorbia hirta L. were conducted for finding identical traits. The fresh hand sections were stained with safranin and examined under light microscope. Cross section of the stem has a circular shape where epidermis was uniseriate and isodiametric. Cortex was distinctly formed with about 5-6 rows composed of chlorenchyma and found laticifers. Tracheary ele...
The present study was aimed to investigate foliar anatomy and flower, fruit and seed morphology of three subspecies of Agrimonia eupatoria (i.e. A. eupatoria subsp. eupatoria, A. eupatoria subsp. grandis and A. eupatoria subsp. asiatica) and the species of Aremonia agrimonioides, belonging to the subtribe Agrimoniiae (Rosaceae) in Iran. Firstly, plant specimens were collected and then identifie...
The Trialeurodes vaporariorum first instars (crawlers) are mobile and able to choose the optimal spots on leaf for 
 constant feeding favorable pest development. Spatial distribution of larvae adults cucumber Ginga F1 cotyledon leaves, as well morpho-anatomical structure cotyledons cross sections have been studied in laboratory. Some differences topology sites between were revealed. Female...
The anatomical and morphological parameters of the leaf blade Forsythia suspensa were investigated to determine species’ stability in Kyiv metropolis (Ukraine) conditions monitor environmental pollution. leaves F. selected at four monitoring sites Kyiv, which differed their distance highways intensity traffic. histological structure changed toward xeromorphism variants where plants exposed incr...
The size and shape of the plant leaf is an important agronomic trait. To understand the molecular mechanism governing plant leaf shape, we characterized a classic rice (Oryza sativa) dwarf mutant named narrow leaf1 (nal1), which exhibits a characteristic phenotype of narrow leaves. In accordance with reduced leaf blade width, leaves of nal1 contain a decreased number of longitudinal veins. Anat...
