Asteraceae are especially common in open and dry environments. [7] Many members of Asteraceae are pollinated by insects, which explains their value in attracting beneficial insects, but anemophily is also present (e.g. Ambrosia, Artemisia). There are many apomictic species in the family.
This is true for all members of the Asteraceae family. [23] After pollination, they mature in 3–4 weeks [ 15 ] and become gray or tan with an oblong-obovoid shape, 1.3–2.2 mm (0.051–0.087 in) in length with 3–5 nerves , and with a few stiff, slender bristles on their surfaces ( strigillose ).
Maize (Zea mays, Poaceae) is the most widely cultivated C 4 plant.[1]In botany, C 4 carbon fixation is one of three known methods of photosynthesis used by plants. C 4 plants increase their photosynthetic efficiency by reducing or suppressing photorespiration, which mainly occurs under low atmospheric CO 2 concentration, high light, high temperature, drought, and salinity.
This is true for all members of the Asteraceae family. [8] After pollination, they mature and become gray or tan with an obovoid shape (like an egg), 1–1.8 mm long with 4–5 faint nerves, and sparsely strigillose (with a few stiff, slender bristles) or sericeous (silky-looking) on their surface.
Flaveria is a genus of plants in the family Asteraceae. [3] [4] They are sometimes called yellowtops. Some are annual or perennial herbs and some are shrubs. They bear yellow flowers in heads, with zero, one, or two ray florets in each head. [5] These plants are found in the Americas, Asia, Africa, and Australia. [5] [6]
Symphyotrichum undulatum (formerly Aster undulatus) is a species of flowering plant in the family Asteraceae native to eastern North America. Its common name is wavyleaf aster, [3] and it is a perennial, herbaceous plant that flowers August through October and may reach heights between 30 and 160 centimeters (1 and 5 feet).
Unlike most tubers, but in common with many other members of the Asteraceae (including the artichoke), Jerusalem artichoke tubers store their carbohydrate as inulin (not to be confused with insulin) rather than as starch. This has made them an important source of inulin used as a dietary fiber in food manufacturing. [41]
Symphyotrichum dumosum (formerly Aster dumosus) is a species of flowering plant of the family Asteraceae commonly known as rice button aster [3] and bushy aster. [4] It is native to much of eastern and central North America, as well as Haiti and Dominican Republic. [4] It is a perennial, herbaceous plant that may reach a height of 1 meter (3 ...
