Mimosa pudica (also called sensitive plant, sleepy plant, [citation needed] action plant, humble plant, touch-me-not, touch-and-die, or shameplant) [3] [2] is a creeping annual or perennial flowering plant of the pea/legume family Fabaceae. It is often grown for its curiosity value: the sensitive compound leaves quickly fold inward and droop ...
Peach leaf curl is a plant disease characterized by distortion and coloration of leaves and is caused by the fungus Taphrina deformans, [1] which infects peach, nectarine, and almond trees. T. deformans is found in the United States , Europe , Asia , Africa , Australia , and New Zealand . [ 2 ]
Maize dwarf mosaic virus (MDMV) is a pathogenic plant virus of the family Potyviridae.Depending on the corn plant’s growth stage, the virus can have severe implications to the corn plant’s development which can also result in economic consequences to the producer of the crop.
Temperature Extremes. The ideal temperature range for a prayer plant is between 60 to 80 degrees Fahrenheit, says Langelo. Any temperature that is lower or higher can cause the leaves to curl.
Curly top is characterized by stunting of the plant and deformation of leaves and fruit. The petioles and blades of the leaves curl, twist, and become discolored. [2] Beet curly top virus causes curly top disease in beets and is carried by the beet leafhopper (Circulifer tenellus) [3] throughout arid and semi-arid locations. [4]
The precise physiological mechanism enabling plant thermotropism is not yet understood. [4] It has been noted that one of the earliest physiological responses by plants to cooling is an influx of calcium ions from the cell walls into the cytosol, which increases calcium ion concentration in the intracellular space.
Calcium deficiency symptoms appear initially as localized tissue necrosis leading to stunted plant growth, necrotic leaf margins on young leaves or curling of the leaves, and eventual death of terminal buds and root tips. Generally, the new growth and rapidly growing tissues of the plant are affected first.
The tree was so named for waving its branches, c.f. Middle Dutch wepelen "totter, waver", Frisian wepeln, German wippen. [9] The name whippletree, also whiffle-tree, now refers to an element of the traction of a horse-drawn cart linking the draw pole of the cart to the harnesses of the horses in file. In this sense it is first recorded in 1733.
