Spiny Hopsage Fruit and Seed Morphology
Journal of Range Management, 1996Rangeland seedings of spiny hopsage (Grayia spinosa [Hook.] Moq.) may be made with either bracted utricles or seeds. Problems have resulted from inconsistent use of terminology describing these 2 structures and the fact their germination and seedling emergence is not the same with similar environmental conditions and seeding techniques. We examined the

SEED MORPHOLOGY AND SYSTEMATICS OF MENYANTHACEAE
American Journal of Botany, 1992Scanning electron microscopic investigations of seed morphology of the five genera of Menyanthaceae illustrate a remarkable diversity of seed characteristics for a small family. Seeds of the monotypic northern hemisphere Menyanthes and Fauria are unomamented and similar, and those of the monotypic Liparophyllum of New Zealand and Tasmania are similar ...

Seed morphology of 17 Dendrobium species from Yunnan
China Journal of Chinese Matera Medica, 2010Seed morphology of 17 Dendrobium species from Yunnan were observed under light microscope and environment scanning electron microscope and 16 of them were reported first time. All seeds were yellow and fusiform, but big differences existed in sizes of seeds and embryos, which were not significantly related to the division of sections under Dendrobium ...

Seed Dormancy and Seed Morphology Related to Weed Susceptibility to Biofumigation
Weed Science, 2017Biofumigation is practiced to control soilborne pests and weeds in agronomic fields. The objectives of this research were to assess the dose response of weed seeds to Indian mustard biofumigation and associate responses to seed dormancy state, initial dormancy, and seed parameters. A petri dish biofumigation methodology was developed to expose seeds of

Predispersal Seed Predation in Leguminous Species: Seed Morphology and Bruchid Distribution
Oikos, 1995We measured and calculated seed morphological parameters [axonometric linear measures, weight, volume and minimum-maximum seed size ratio (SMIMA)] of 110 leguminous plant species occurring in Hungary. We collected seed samples, reared the predispersal seed predators from the samples, took morphological data from the bruchids (elytra length, body width,

Seed morphology in Southern AfricanOrchidoideae (Orchidaceae)
Plant Systematics and Evolution, 1993The seed morphology of 151 species of Southern AfricanOrchidoideae (Orchideae andDiseae; sensuDressler 1981) was studied by means of scanning electron microscopy. Two different seed types were found. (1) In the majority of species the seeds are minute and fusiform.

Aerodynamics Properties of Silflower Seed: Effect of Moisture and Seed Morphology
Journal of the ASABEHighlights Terminal velocity increased linearly with moisture (10%–15% d.b.) for both silphium seed types. Wingless SP-16 type exhibited higher terminal velocity and densities than winged CP-16 type.
