diaspore

The structure known as seed by the agronomists and used for the sexual production of yellow mombin, is a diaspore of the nuculanic type (CAVALCANTE et al., 2009; CARVALHO; NAKAGAWA, 2012) from the botanical point of view.

Bauxite is a mixture of minerals such as gibbsite, boehmite and diaspore, iron oxides such as goethite and hematite, clay mineral kaolinite and some amounts of anatase.

In this sense, one of the most important structural components of wetland ecosystems is the diaspore bank, defined as an aggregation of non germinated seeds, potentially capable of replacing adult plants (Bakker, 1989).

Lower Miocene leaf, palynomorph, and diaspore assemblages from the base of the lignite-bearing sequence in the opencast mine Obcrdorf, N Voitsberg (Styria, Austria) as an indication of <<Youngcr Mastixioid>> vegetation.

John Bradshaw, Coast-to-Coast Rare Stones International, Nashua, New Hampshire, USA, for 21 bags containing part-cut crystals of: apatite (Canada and Mexico), cassiterite (Namibia), celestine (Kansas, USA), cerrusite (Namibia), crocoite (Tasmania, Australia), diaspore (Turkey), oligoclase (Kenya), pollucite (Conneticut, USA), scheelite (Pakistan and Arizona, USA), smithsonite (Namibia), sphalerite (Spain), tourmaline (Maine, USA, and Afghanistan), tugtupite (Greenland), willemite/leucophoenicite (New Jersey, USA) and zincite on calcite (New Jersey); and also for 95 faceted mixed-shape tourmalines, mostly pink, green and blue.

X-ray diffraction (XRD) analyses show that the Zan laterites consist of kaolinite, diaspore, hematite, goethite, boehmite, anatase, siderite, rutile, and quartz.

The main minerals of this group are: Brucite, Geothite, Diaspore, Bauxite, Lepidocrocite, Manganite, Groutite, Stainierite and Chalcopanite that this project discusses the diaspore minerals and processing of them from the diaspore minerals.

Previous studies showed that diaspore mass and shape differed significantly among phylogenetic groups and dispersal syndromes in this desert [31].

the Keystone Trappe Rock quarry at Cornog (exquisite small specimens of Alpine-type cleft minerals), Brinton's quarry at Darlington's Corners (the world's best large clinochlore crystals), the Poorhouse quarry, West Bradford Township (excellent microcline), Corundum Hill, Newlin Township (good corundum and superb diaspore crystals), the fields around Parkesburg where line rutile crystals may still be found loose in the soil.

Diaspore morphology and seed dispersal in several wind-dispersed Asteraceae.

Fruiting periodicity depends principally on flowering, but it is also influenced by environmental conditions appropriate for fruit development, diaspore dispersal, and seedling establishment (Rathcke and Lacey, 1985; Ibarra-Manriquez et al., 1991; van Schaik et al., 1993).
