The scutellum is part of the structure of a barley and rice [1] seed—the modified seed leaf. The scutellum (from the Latin scutella meaning "small shield") can also refer to the equivalence of a thin cotyledon in monocots (especially members of the grass family ).
The plant is referred to by the Indians of Iowa as Tipsina, the seed-bearing plant is due to climatic conditions especially in high, dry spots and can be found near rivers or in the steppe. [b] The relative scarcity of the plant today compared to its previous abundance may be because most prairie has been converted to farmland or managed grassland.
The cotyledon of grasses and many other monocotyledons is a highly modified leaf composed of a scutellum and a coleoptile. The scutellum is a tissue within the seed that is specialized to absorb stored food from the adjacent endosperm. The coleoptile is a protective cap that covers the plumule (precursor to the stem and leaves of the plant).
Scutellum may refer to: Scutellum (insect anatomy), a term used in the anatomy of arthropods; Scutellum (botany), a term used in the morphology of grasses;
Seed production in natural plant populations varies widely from year to year in response to weather variables, insects and diseases, and internal cycles within the plants themselves. Over a 20-year period, for example, forests composed of loblolly pine and shortleaf pine produced from 0 to nearly 5.5 million sound pine seeds per hectare. [ 60 ]
These small true bugs are almost spherical or trapezoidal in shape and shiny deep black, sometimes with green, blue or bronze gloss. The side edges of the abdomen are yellow. The scutellum covers the abdomen and the tarsus is bipartite. [2] [3]
Scutelleridae is a family of true bugs.They are commonly known as jewel (stink) bugs or metallic shield bugs due to their often brilliant coloration. With the name based on the Asian genus Scutellera, they are also known as shield-backed bugs due to the enlargement of the thoracic scutellum into a continuous shield over the abdomen and wings. [1]
Epeolus cruciger is a small bee in which the females have a reddish scutellum and tend to have entirely red legs. The fifth sternite is straight when viewed from the side and from below it is noticeably wider than it is long. The abdomen is nearly completely reddish. The males have a dark scutellum (scutellum dark) usually have a reddish ...
