What is waterlogging stress?
Waterlogging is one of the main abiotic stresses suffered by plants. Inhibition of aerobic respiration during waterlogging limits energy metabolism and restricts growth and a wide range of developmental processes, from seed germination to vegetative growth and further reproductive growth.
What is plant waterlogging?
Waterlogging occurs when the soil and root zone around plants becomes saturated. Basically, the water can’t drain away fast enough. This happens when more rain falls than the soil can absorb or evaporate into the air. This can happen with an intense period of rainfall such as summer storms.
Do cucumbers have adventitious roots?
Cucumber has the capacity to create adventitious roots above the base of the stem.
What are the causes of waterlogging?
Waterlogging is caused by a combination of excess rainfall (for the site), poor external drain- age (runoff), poor internal drainage (water movement in the soil profile) and the inability of the soil to store much water.
How do you overcome waterlogging and salinity?
Conventional wisdom holds that the best solution to dealing with the twin menace of salinity and waterlogging, is to maintain a net flux of salt away from the rootzone and to control the watertable by means of artificial drainage.
How waterlogging can be detected?
The best way of keeping watch over the problem of waterlogging is by observing variations in the groundwater level. It can be done by measuring the depth of water levels at regular interval in the wells dug in the area.
Do watermelon have adventitious roots?
In annual vegetable crops, including the grafted crops of the Solanaceae (tomato, pepper) and Cucurbitaceae (melon, watermelon) families, root system function relies partially on adventitious roots that develop from the hypocotyl (basal roots) or from the main stem, and this makes a contribution to root vigour which is …
What are the solutions of waterlogging?
The problem of waterlogging can be solved by building a proper rainwater drainage network so that the excess water during rainy days can be directly discharged into nearby canals, open fields or in rivers.
How do you control water logging?
Methods to control water logging.
- Adequate surface drainage :
- Efficient under-drain :
- Controlling loss of water by seepage from the canals :
- Increasing the outflow and preventing the inflow :
- Changing the system of irrigation :
- Pumping out surplus water :
- Prevention of seepage from reservoir :
- Lining of field channels :
What are the causes of water logging?
Water-logging is, however, caused mainly because of manmade factors like deforestation and poor upkeep of watersheds; developmental activities such as construction of roads, bridges, railway lines and buildings resulting in choking of natural drainage; hydraulic pressure of water from upper irrigated areas resulting in …
What gets waterlogged easily?
Clayey soil is rich in minerals. Many of which are used by the plants. Clayey soil is very dense, more porous and less permeable. As a result, clayey soil gets easily waterlogged during the rainy season, reducing air availability between the soil particles, making the soil infertile.
