罂粟唯美高清电脑壁纸
The Poppy is a flowering plant of the family Papaveraceae. Ornamental poppies are grown for their colorful flowers; some species of poppy are used as food, whilst other species produce opium which contains powerful medicinal alkaloids such asmorphine which have been used since ancient times to create analgesic and narcotic medicinal and recreational drugs. Following the trench warfare of the 1st World War which took place in the poppy fields of Flanders, red poppies have become a symbol of remembrance of soldiers who have died during wartime.
Poppy flowers have 4 to 6 petals, many stamens forming a conspicuous whorl in the center of the flower and an ovary consisting of from 2 to many fused carpels. Poppies can grow to be over 4 feet tall and 6 inches across. The petals are showy, may be of almost any color and some have markings. The petals are crumpled in the bud and as blooming finishes, the petals often lie flat before falling away. Poppies are in full bloom late spring to early summer (Simon, Chadwick, and Craker 1984). Most species secrete latex when injured. The pollen of the oriental poppy, Papaver orientale, is dark blue. The opium poppy, Papaver somniferum, is mainly grown in eastern and southern Asia, and South Eastern Europe. It is believed that it originated in the Mediterranean region (Jonsson and Krzymanski, 1989). The pollen of the field poppy or corn poppy (Papaver rhoeas) is dark green to grey.[1] Bees use poppies as a pollen source.
