Opuntia is the most diverse and widely distributed drought resistant promising genus of family Cactaceae. The cladodes were utilized to quantify chemical composition these plants helpful in lignocellulose conversion their application towards biofuel production. present study was aimed evaluate compare taxonomic relationship based on morphology, stem anatomy palynology important desert cacti including dillenii monacantha. This also evaluates potential usefulness morphological, anatomical pollen traits using light scanning electron microscopy. obtained microcharacters flowers are considered diagnostic at generic specific levels. Some distinguishing morphological features observed elliptical obovate cladodes, 1-7 spines per areole presence glochidia O. dillenii. Pollen characters studied taxa highly species epidermis has irregular wavy cells, with straight sinuate wall pattern paracytic stomata. grains appear as pantoporate prolate spheroidal having reticulate perforate-reticulate sculpturing while exine semi-tectate tectate. could be valuable elaborate correctly identification species. methods microscopic examination providing sufficient evidence about taxonomy RESEARCH HIGHLIGHTS: Description illustration Opuntia.

This research aimed to explore the melliferous bee flora pollen from arid zones of District Attock, Islamabad Capital and Rawalpindi. Morpho-palynological features has provided key information for classification help explain taxonomy several genera species. Therefore, in this work, we examined morphological characters potentially be used species delimitation flora. A total 18 floral species, classified into 12 different families were collected, pressed, identified then acetolyized observe grains under microscopy. Bee can described by small, medium large sized morphotypes presenting five types shapes, prolate spheroidal (seven species), sub-prolate (six oblate (three (one each) was examined. The observed polar equatorial diameter found maximum Zea mays 73.5 μm Pelargonium inquinans 66.75 respectively. Pollen six namely: tricolporate, 3-zonocolporate, monoportae, tetracolporate, tetraporate mononsulcate. Whereas highest value colpi length measured Grewia tenax (24.55 μm). Exine surface nature echinate psilate scabrate. thickness noted Verbena tenuisecta (8.40 μm) minimum Citrus macrocarpa (0.4 considered difficult identify based on other traits successfully distinguished using quantitative qualitative traits, confirming importance morphology diagnose correctly honeybee RESEARCH HIGHLIGHTS: diversity among Highly variations via microscopy micromorphology.

The family Euphorbiaceae is one of the most taxonomically complex and diverse among angiosperm. Therefore, this study aims to document pollen morphology taxa collected from different geographical regions Hainan Island South China, strengthen taxonomy support subfamilial classification. includes 23 species 10 genera bi-ovulate subfamily Phyllanthoideae tri-ovulate Crotonoideae, Euphorbioideae, Acalyphoideae were examined under light scanning electron microscopy. principal component analysis was performed by using six variables show variation relationships between species. A significant found in (exine colpus sculpturing). croton-type pattern diagnostic trait Crotonoideae. Euhphorboideae mostly homogenous however, muri pattern. Acalyphoideae, have fossulate scabrate verrucate exine sculpturing that can delimit rest sub-families. Phyllanthoideae, showed reticulate exine, tri tetra-colporate having various morphology. maximum size Croton hirtus (59.49 × 60.86 μm) minimum Acalypha indica (10.86 73 μm). Similarly, width observed Euphorbia pulcherrima (8.3 Hence traits relevance phylogenetic define boundaries at taxonomic levels. This subfamilies fill palynological gap these will contribute future systematic studies Euphorbiaceae.Some selected four including (Euphorbiaceae) Island. both qualitative features surface membrane morphology) quantitative (polar axis, equatorial diameter, length width, polar area clava diameter.

Pollen Morphological Peculiarities of Selected Mimosoideae Taxa of Hainan Island and Their Taxonomic Relevance

Agronomy, Год журнала: 2022, Номер 12(5), С. 1122 - 1122

Опубликована: Май 6, 2022

Mimosoideae is one of the taxonomically complex subfamilies Fabaceae. Several studies have reported pollen morphology taxa and their taxonomic relevance, but no such study was found specifically for Hainan Island in southern China. Therefore, present designed to investigate selected explore new palynological traits support strengthen systematics using multiple microscopic techniques. The polar axis, equatorial diameter grains, colpus length width were measured. smallest grain size Mimosa pudica (7.8 × 7.75 µm), while largest Albizia lebback (87.54 77.97 µm). Similarly, significant variation exine surface patterns. subfamily considered eurypalynous because traits. In addition, also quantitative Comparatively, features be helpful at genus species levels, as well correct identification discrimination taxa. Hence, this gives a detailed account morphologies certain collected from different geographical regions on Island. morphological proven potential can used additional tools These results will provide basis further systematic studies.

Pollen micromorphology is not only used to check the functional and structural evolution in plants but also solve taxonomic problem related classification of plants. Therefore, keeping view significance pollen traits, selected taxa subfamily Caesalpiniaceae was collected from different geographical regions Pakistan. The species were then analyzed under both light microscopy scanning electron techniques investigate importance micromorphological characters identification species. Great variation recorded equatorial shape, surface ornamentation, tectum, polar diameter, exine thickness. However, little observed type, fertility pollen. shape five types observed: prolate, prolate-spheroidal, spheroidal-subprolate, subspheroidal-prolate, subspheroidal. Four psilate, granulate, clavate, perforate, recorded. Tectum types, intactate, reticulate regulate, medium reticulate, tactate, striate, observed. Sexine thicker than nexine all studied largest diameter Caesalpinia pulcherrima 64.1 μm while smallest Parkinsonia aculeata 26.1 μm. found C. 70.25 whereas P. 27.57 All pollens tricolporate. have a ratio more 90%. A key developed show features delimit for correct identification. In conclusion, traits useful define boundaries at various ranks will strengthen taxonomy this subfamily. Besides, study explored palynological their implication Caesalpiniaceae.
