Buzz pollination, or sonication, serves as an example of a behavioral response to specific frequencies of vibrations in plants.Some 20000 plants species, [7] including Dodecatheon and Heliamphora have evolved buzz pollination in which they release pollen from anthers only when vibrated at a certain frequency created exclusively by bee flight muscles.
In most cases, the wilt phase occurs on seedlings, but for certain corn types (i.e. sweet corn), more mature plants can wilt. The wilt phase is systemic, meaning the majority of the plant is infected via bacterial movement and colonization of the plant's vascular system. When the bacterium spreads within the plant, leaves begin withering and ...
A simple soil moisture sensor for gardeners. Soil moisture sensors measure the volumetric water content in soil. [1] Since the direct gravimetric measurement of free soil moisture requires removing, drying, and weighing of a sample, soil moisture sensors measure the volumetric water content indirectly by using some other property of the soil, such as electrical resistance, dielectric constant ...
Watering daily or letting plants sit in water leads to root rot, yellowing leaves, or pests like a fungus gnat invasion. Observe the foliage. If the leaves are wilted, the plant may need water.
The tassel of a corn plant. Detasseling corn is removing the pollen-producing flowers, the tassel, from the tops of corn (maize) plants and placing them on the ground. It is a form of pollination control, [1] employed to cross-breed, or hybridize, two varieties of corn. Fields of corn that will be detasseled are planted with two varieties of corn.
A satellite image of circular fields characteristic of center pivot irrigation, Kansas Farmland with circular pivot irrigation. Center-pivot irrigation (sometimes called central pivot irrigation), also called water-wheel and circle irrigation, is a method of crop irrigation in which equipment rotates around a pivot and crops are watered with sprinklers.
Phosphorus deficiency on corn. Phosphorus deficiency is a plant disorder associated with insufficient supply of phosphorus. Phosphorus refers here to salts of phosphates (PO 3− 4), monohydrogen phosphate (HPO 2− 4), and dihydrogen phosphate (H 2 PO − 4).
A snake plant left on top of a filing cabinet in an office cubicle far from a window won’t need watering as much as the same plant set in front of a sunny, southern-facing window. Tips for ...
