Eichornia crassipes

Waterhyacint Eceng gondok Pontederiaceae


Eichornia crassipes, Waterhyacint, Eceng gondok


Eichornia crassipes, Waterhyacint, Eceng gondokWater Hyacinths are the only large aquatic herb thaEichornia crassipes, Waterhyacint, Eceng gondokt can float on the water unattached to the bottom.
They float on bloated air-filled hollow leaf stalks. Their roots trail underwater in a dense mat.
The seeds are dispersed by birds and can remain viable for 15-20 years.
But the main method of reproduction is vegetatively, through stolons.
A single plant under ideal conditions can produce 3,000 others in 50 days and cover an area of 600 sq metres in a year.The fast-growing Water Hyacinth soon becomes a noxious weed outside its native habitat. Plants interlock in such a dense mass that a person could walk on it.
They clog waterways preventing river travel, block irrigation canals, destroy rice fields, ruin fishing grounds
Water Hyacinths are difficult (if not impossible) to destroy.
In the US, arsenic fire and explosives was used .Fire and explosives were also attempted,
but the plants reproduce rapidly even from the tiniest fragment and simply grew back.
The most effective measures are biological controls,
Two weevils, a moth and two types of fungi have been introduced to successfully control the plant.
Other creatures that keep the plant in check include fish. Uses :it was cultivated as pig food,
In their native habitat of the Amazon, Water Hyacinths provide food
for their natural predators which voraciously keep the plant in check.
The annual flooding of the Amazon also flush out huge quantities to sea each year.
