Vaccinium virgatum is a deciduous shrub growing to 3 to 6 feet tall and with up to a 3-foot spread. [4] The leaves are spirally arranged, oblate to narrow elliptic, 3 inches long and start red-bronze in the spring only to develop into a dark-green. [4]
Vaccinium darrowii is an evergreen shrub growing to 30–120 cm (1–4 ft) tall, with small, simple ovoid-acute leaves10–15 millimetres (3 ⁄ 8 – 5 ⁄ 8 in) long and in non-hybrid forms are a light blue-green color on the base of the plant and a light pink color at the tips of the branches.
Habropoda laboriosa, the southeastern blueberry bee, is a bee in the family Apidae.It is native to the eastern United States. [1] It is regarded as the most efficient pollinator of southern rabbiteye blueberries, because the flowers require buzz pollination, and H. laboriosa is one of the few bees that exhibit this behavior.
The rabbiteye blueberry (Vaccinium virgatum syn. V. ashei) is a southern type of blueberry produced from the Carolinas to the Gulf Coast states. Production of rabbiteye blueberries was a focus in Texas in the early 21st century. [17] Other important species in North America include V. pallidum, the hillside or dryland blueberry.
Allogamy ordinarily involves cross-fertilization between unrelated individuals leading to the masking of deleterious recessive alleles in progeny. [11] [12] By contrast, close inbreeding, including self-fertilization in plants and automictic parthenogenesis in hymenoptera, tends to lead to the harmful expression of deleterious recessive alleles (inbreeding depression).
Cross-pollination involves the transfer of pollen grains from the flower of one plant to the stigma of the flower of another plant. The main characteristics which facilitate cross-pollination are: Herkogamy : Flowers possess some mechanical barrier on their stigmatic surface to avoid self-pollination, e.g. presence of gynostegium and pollinia ...
Few flowering plants self-pollinate; some can provide their own pollen (self fertile), but require a pollinator to move the pollen; others are dependent on cross pollination from a genetically different source of viable pollen, through the activity of pollinators. One of the possible pollinators to assist in cross-pollination are honeybees.
Entomophily is a form of plant pollination whereby pollen is distributed by insects, particularly bees, Lepidoptera (butterflies and moths), flies and beetles. Honey bees pollinate many plant species that are not native to their natural habitat but are often inefficient pollinators of such plants; if they are visiting ten different species of ...
