What is an example of allelopathy?
Allelopathic Trees Trees are great examples of allelopathy in plants. For instance, many trees use allelopathy to protect their space by using their roots to pull more water from the soil so other plants cannot thrive. Some use their allelochemicals to inhibit germination or impede the development of nearby plant life.
What does an allelopathic plant do to other plants?
Allelopathic plants release chemical compounds from their roots into the soil, and these chemicals suppress or even kill the neighboring plants when they are absorbed by the plants. The harmful chemicals released by allelopathic plants are known as allelochemicals.
How allelopathy affect the production of crops?
It was found that allelochemicals promote plant growth and production at low concentration; however it can suppress the growth if applied at high concentrations, for that can be used allelopathic compounds for weed control by used high concentrations of plant residues or aqueous extracts of plant.
What factors might affect the allelopathic effect?
Environmental conditions can directly or indirectly affect the allelopathic performance of a plant. The most important environmental factors that influence allelopathy include UV radiation, temperature, water and nutrient availability and competition stress (Croteau et al. 2000.
What is meant by allelopathic?
al·le·lop·a·thy. (ə-lē-lŏp′ə-thē, ăl′ə-) n. A usually negative effect on the growth or development of an organism of one species, caused by a chemical released by an organism of another species. Usually used of plants.
What are allelopathic plants?
Plant allelopathy is one of the modes of interaction between receptor and donor plants and may exert either positive effects (e.g., for agricultural management, such as weed control, crop protection, or crop re-establishment) or negative effects (e.g., autotoxicity, soil sickness, or biological invasion).
What are the negative effects of allelopathy?
The negative effects of allelopathy diminished with study duration, and increased with concentrations of leachates or residues. Although allelopathy was not significantly related to lifespan, life form or domestication of the interacting plants, it became more negative with increasing phylogenetic distance.
What causes allelopathy in plants?
Allelopathy refers to the chemical inhibition of one species by another. The “inhibitory” chemical is released into the environment where it affects the development and growth of neighboring plants. Allelopathic chemicals can be present in any part of the plant.
What is allelopathy in agriculture?
Allelopathy is a sub-discipline of chemical ecology that is concerned with the effects of chemicals produced by plants or microorganisms on the growth, development and distribution of other plants and microorganisms in natural communities or agricultural systems (Einhellig, 1995).
What causes allelopathy?
Allelopathy occurs when one plant species releases chemical compounds, either directly or indirectly through microbial decomposition of residues, that affect another plant species.
What are the benefits of allelopathy?
Farmers can use allelopathic plants to trigger the germination of weed seeds dormant in the soil, so that they can grow out and be removed before planting of the main crop. To control weeds with residues – Selectively toxic plant residues can be managed in a proper manner to control weeds efficiently.
What are the consequences of allelopathy?
Although the protection of donor plant species from adverse biotic conditions can also be considered as one of the consequences of allelopathy [88].
What are allelopathic interactions?
Allelopathic interactions are an essential factor in determining species distribution and abundance within plant communities and are also thought to be important in the success of many invasive plants. Allelopathic chemicals can be present in any part of the plant.
How do Allelopathic plants affect the environment?
Allelopathic plants prevent other plants from using the available resources and thus influence the evolution and distribution of different species. One might say that allelopathic plants control the environments in which they live. Though a considerable number of plants in nature show allelopathic behavior.
What are some examples of allelopathy?
Common plants with allelopathic properties can be seen and include: English laurel (Prunus laurocerasus) Bearberry (Arctostaphylos uva-ursi) Sumac (Rhus) Rhododendron Elderberry (Sambucus) Forsythia Goldenrod (Solidago) Some types of fern Perennial rye Tall fescue Kentucky bluegrass Garlic Mustard Weed
