The micromorphological typology of seed surfaces was investigated in rapid-cycling Brassica (RCBr) forms, using scanning electron microscopy. Four types of basic ornamentation pattern were recognized: reticulate (B. rapa, B. juncea), reticulate-foveolate (B. nigra), randomly reticulate (B. oleracea, B. napus) and reticulate-rugose (B. carinata). The seed coats showed variation in the shape and ...

This review is concerned with some key features observed within grouped samples of ancient ceramics that provide important evidence concerning the selection appropriate raw materials and evolution firing technologies employed in their production. It also demonstrates importance distinguishing accounting for mineralogical microstructural attributes identifying processes responsible these ceramic...

This study reports a high-resolution micromorphological characterization of floodplain deposits to investigate the relationships among compositional, textural and geotechnical data, integrate soil micromorphology with sequence stratigraphy. Compositional facies associations features are calibrated against parameters. The latter, obtained from cone penetration pocket penetrometer tests borehole ...

The purpose of this study was to investigate the micromorphological features tongue domestic turkey (Meleagris Gallopavo). studied by means histological and histochemical methods elucidate its features. Six adult male turkeys were used in study. Samples from tip, body root portions fixed 10% neutral buffered formalin. Stained sections with H&E revealed that lingual mucosal lining is stratified ...

Plant cuticles are covered by epicuticular waxes with considerable ultrastructural and chemical diversity and have great systematic significance. Pinus elderica is a rare pine found naturally only in desert environment southeast of Tbilisi (Georgia). This tree have been probably introduced to Iran about 800 years ago and gradually altered in both shape and size in Nashtifan-Khaf, and changed in...

Abstract The leaves of different species the genus Artemisia show considerable inner and external structural diversity. This paper presents a comparative study micromorphological features leaf surface for seven from regions Ukraine: A. absinthium L., annua dracunculus marschalliana Spreng., vulgaris argyi H.Lév. & Vaniot, verlotiorum Lamotte. vegetative organs these plants have potentially ...

introduction: soil genesis and development in arid and semi-arid areas are strongly affected by geological formations and geomorphic surfaces. various morphological, physical, and geochemical soil properties at different geomorphic positions are usually attributed to different soil forming factors including parent material and climate. due to variations in climate, geological formations (quater...
