Gleditsia sinensis Lam. (Fabaceae) is an endemic species in China, which has a wide range of ecological functions and high economic value. G. belongs to androdioecy, the stamens perfect flowers are aborted, meaning that flower functional female flower. Understanding dynamic process flowering characteristics pollen morphology effectively determine viability vitality, suitable conditions for short-term storage can provide theoretical basis technical reference hybrid breeding germplasm conservation sinensis. In this study, male plants Guiyang area were used as research materials. The was recorded through field observation. observed analyzed with scanning electron microscope (SEM). germination studied vitro method, vitality also determined using four staining methods. effects different temperatures water contents on rate discussed. results showed had short, single period, lasting 2–3 days from opening shedding. artificially divided into five stages. Pollen grains oblate spheroidal, tricolporate equatorial elongated endoapertures sporoderm surface reticulate.

Every pollen grain tells a story: A palynological analysis of selected melliferous plant species native to the Sahara Desert with implications for honey origin determination

Current Plant Biology, Год журнала: 2024, Номер 38, С. 100348 - 100348

Pollen analysis is essential for discerning the botanical and geographical origins of honey, ensuring authenticity, quality, commercial value. The Sahara Desert in Algeria boasts unique floral diversity, with its melliferous plant species contributing to regional honey production. Nevertheless, a lack comprehensive information on pollen characteristics these plants impedes precise identification Saharan honeys. Given importance understanding origin quality assurance, this study addresses challenge posed by scarcity melissopalynological data Desert. By offering detailed characterization pollen, research contributes valuable insights broader field authentication underscores significance industry. Therefore, was conducted characterize Desert, which establishing database that can aid determination origins, protect against fraudulent activities, support conservation efforts. This aimed at spontaneous from facilitate honeys produced region. In three regions (Ghardaïa, Touggourt Ouargla), morphological features namely: polar length (PL) equatorial diameter (ED), size, shape, apertures exine ornamentations 19 native were studied through sampling ten flowers per grains flower each (n = 3800 measurements). surveyed showed medium-sized pollens (25–50 µm) most dominant (73.34%), followed slam-sized (21.18%), smallest size observed Tetraena alba (PL 18.98 ± 4.82 μm, ED 18.95 5.06 μm) largest measured Faidherbia albida 58.03 4.65 µm, 57.46 4.70 μm). frequent forms different prolate-spheroidal (32.68%) oblate-spheroidal (26.53%). Diverse types detected unit level dominance reticulate (57.89%). Tricolporate (42.11%) tricolpate (31.58%) dominate apertures. characterized plants, determination, supporting conservation, implications authentication, protection, preservation resources sustained

Morpho‐palynological and anatomical studies in desert cacti (Opuntia dillenii and Opuntia monacantha) using light and scanning electron microscopy

Microscopy Research and Technique, Год журнала: 2022, Номер 85(8), С. 2801 - 2812

Опубликована: Апрель 12, 2022

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. Morpho-anatomy LM SEM. Highly variation qualitative quantitative features. Systematic significance presented.

Palynology, a prominent field in plant systematics and biodiversity studies, plays vital role identifying determining the species present specific region. The current study was performed to evaluate micromorphological traits of pollen from flora Lesser Himalaya. Pollen microstructural variations aid identification belonging botanical families various geographic habitats. Flowers 24 selected categorized into 16 were collected, preserved then acetolysis protocol followed. examined under light scanning microscopy (LM SEM) for palynomorph description. palynomorphs characteristics such as size, shape, exine surface, aperture orientation, examined. Status these plants show that herbs are being dominant (11 species), while shrubs (7 climbers (3 bulbous (2 small tree, sedge, weed (1 each). shape determined equatorial view were; spheroidal, sub-prolate, oblate-spheroidal, prolate, spherical sub-oblate. seen among types; tricolpate, tricolporate polyporate most species. Exine stratification observed mostly scabrate echinate, cristate-reticulate, granulate, punctate, rugulate-perforate, striate-rugulate, verrucate, cristate-foveolate visualized each different Palynomorph apertural patterns sunken, furrowed, slightly bulged, scabrate, slit like, perforate. largest polar diameter measured Hymenocallis littoralis (138.6 µm) whereas smallest Parthenium hysterophorus (14.70 µm). Equatorial distance calculated maximum Cascabela thevetia (110.1 minimum Hibiscus rosa-sinensis (1.7 P/E ratio (1.8) lowest Duranta erecta (0.89). taxonomic characters investigated can be helpful level provide baseline conduct more systematic research with respect genera.
