A study on foliar epidermis was conducted nine species belonging to the Moraceae family investigate diverse micromorphological characteristics that hold taxonomic importance in leaf epidermis.Based LM (light microscopy) and SEM (scanning electron microscopy), it found shape of epidermal cells studied members is rectangular, irregular, polygonal, pentagonal both surfaces.The common polygonal most species.The size cell length width varies from wall thick species, except Broussonetia papyrifera (L.) L'Hér.ex Vent.and Morus alba L., laevigata Wall.ex Brandis, where are thin surfaces.It majority plants hypostomatic, i.e., adaxial surface leaves has no stomata.Most have anomocytic stomata abaxial leaf.The cyclocytic were only Ficus elastica Roxb.ex Hornem.and benjamina L. The type, which rare cyclocytic, laterocytic, paracytic.We variations surfaces all selected important element stomatal index, serves as a geographic indicator shows transpiration rate index ranges (76.7%) B. (2.13%) F. surface, while highest (61.8%) religiosa lowest (3.06%) virens Aiton.The identification at genus specific-levels be taxonomically appropriate based architecture leaves.Thus, current aims clarify qualitative quantitative properties order give information for categorization.

Applications of scanning electron microscopy in taxonomy with special reference to family Euphorbiaceae

Microscopy Research and Technique, Год журнала: 2020, Номер 83(9), С. 1066 - 1078

Опубликована: Июнь 9, 2020

Abstract The present study was carried out to identify the 20 medicinally important species of family Euphorbiaceae by aid scanning electron microscopy (SEM) foliar anatomical characteristics. Both qualitative and quantitative measurements for characters like epidermal cells, stomata, trichomes, subsidiary cells on both abaxial(ab) adaxial(ad) epidermis were recorded. Remarkable variations in these features had been observed among studied species. Most irregular or polygonal shape, only five hexagonal that is, Euphorbia neriifolia L., prostate Aiton, Jatropha integerrima Jacq., Vernicia fordii (Hemsl.), royleana Boiss. Stomata abundant abaxial as compared adaxial epidermis. E. pulcherrima Willd. Ex Klotzsch Phyllanthus emblica L. possessed anomocytic helioscopia cotinifolia Ricinus communis anisocytic while rest paracytic stomata. Trichomes very few including hirta Klotzsch, Putranjiva roxburghii Wall. Similarly, also reported such can be distinguished from basis length 103.4 ± 0.15 74.9 0.55 μm, respectively. Moreover, trichomes with 408 μm P. trichome 314.2 1.35 These findings confirmed taxonomic utility traits identification taxa.

Seed morphometry and ultrastructure studies on some Turkish orchids (Orchidaceae)

Microscopy Research and Technique, Год журнала: 2021, Номер 84(10), С. 2409 - 2420

Опубликована: Апрель 27, 2021

Abstract Orchid seeds have great morphological variations that imply the phylogenetic relationship of species depending on biodiversity family or act as an adaptation to seed dispersal mechanisms life form. This study aims both describe and analyse qualitative quantitative traits 12 Turkish orchids representing epidendroids orchidoids in detail investigate which properties are diagnostic among these taxa also reveal if differentiated ecological preferences studied species. Both features were determined, measurements obtained using light scanning electron microscopy. We applied unweighted pair group method with arithmetic mean (UPGMA) cluster analysis canonical discriminant traits. Furthermore, we analyzed same orchid correlation such habitats elevation confirmed usefulness data sets for effectively assessing variation seeds. Although characters cell shape differences chalazal medial region, sizes, numbers longitudinal axis, periclinal wall ornamentation taxonomically conserved, some other characteristics shape, absence ornamentation, larger embryo size developmental achievement germination. confirms value features, effective explaining variety.

Comparative authentication of Semiliquidambar cathayensis and its substituted species via macroscopic and microscopic features

Chinese Herbal Medicines, Год журнала: 2022, Номер 14(4), С. 535 - 542

Ban Fenghe recorded in the Quality Standard of Yao Medicine Guangxi Zhuang Autonomous Region (Volume 1) is derived from dried stems and leaves Semiliquidambar cathayensis. It usually confused with medicinal herbs Pterospermum heterophyllum Dendropanax dentiger. However, they are very different chemical composition, should not be used as same drug. To ensure their safety efficacy, a method based on macroscopic microscopic characteristics was developed to distinguish them.A total 14 batches samples three species were collected producing areas China. The examined by observing external traits. tissue structures transverse sections leaves, leaf epidermis, powder observed microscopically.The branchlets surfaces S. cathayensis P. hairy, especially lower densely covered hairs, but those D. dentiger hairless. pericyclic fibers intermittently distributed circular shape accompanied stone cells, whereas bundled without cells. So cells hairs present powder, found powder. distribution sites, sizes types secretory tissues these also leaves. Stomata epidermis paracytic, anomocytic.Ban drugs could readily distinguished features.
