Spindly growth, also known as leggy growth, is a term used when two plants compete for sunlight and nutrients in order to develop. Causes
The leaves of plants experiencing root rot often yellow and die, and if allowed to continue, the condition can be fatal to the plant. To avoid root rot, it is best to only water plants when the soil becomes dry, and to put the plant in a well-drained pot. Using a dense potting media such as one dug up from outdoors can also cause root rot.
Standing water on plant leaf surfaces provides a place for spores to germinate. [12] Humid conditions can result from improper irrigation practice, plants placed too close together, or the structure of the greenhouse not allowing for efficient ventilation and air flow. Ventilation at night significantly reduces the incidence of gray mold. [13]
Trichoderma spp. can also be pathogenic to plants. Trichoderma viride is the causal agent of green mold rot of onion. [ 12 ] A strain of Trichoderma viride is a known cause of dieback of Pinus nigra seedlings.
There are steps you can take to reduce your risk of exposure to mold spores and prevent mold from growing on foods, according to the experts and the USDA: Discard all food growing mold Do not ...
Pioneer species tend to be fast-growing, shade-intolerant, and tend to reproduce large numbers of offspring quickly. The seeds of pioneer species can sometimes remain viable for years or decades in the soil seed bank and often are triggered to sprout by disturbance. [19] Mycorrhizal fungi have a powerful influence on the growth of pioneer ...
It's here where land managers, researchers and volunteers hope the seedlings will form islands of trees that can help regenerate more trees by producing their own seeds over time. The Nature Conservancy used donations to purchase a total of 5,000 seedlings. New Mexico Highlands University is contributing another 3,500 seedlings.
Pythium. Pythium-induced root rot is a common crop disease. When the organism kills newly emerged or emerging seedlings, it is known as damping off, and is a very common problem in fields and greenhouses. [2]
