The plant invaded Florida in 1890, [55] and an estimated 50 kg/m 2 of the plant mass choked Florida's waterways. [56] The clogging of the St. Johns River was posing a serious threat, and in 1897 the government dispatched a task force of the United States Army Corps of Engineers to solve the water hyacinth problem plaguing Gulf states such as ...
Wisconsin Fast Plants were initially developed as part of a larger breeding project of Rapid-Cycling Brassicas, originating in the early 1970s. [1] Wisconsin Fast Plants and other Rapid-Cycling Brassicas were selected through conventional plant breeding to be a tool that would speed up genetic research for disease resistance in economically important Brassica crops.

Due to the plants continuous fight against gravity, plants typically mature much more quickly than when grown in soil or other traditional hydroponic growing systems. [55] Because rotary hydroponic systems have a small size, they allow for more plant material to be grown per area of floor space than other traditional hydroponic systems.
The Kratky method is a passive hydroponic technique for growing plants suspended above a reservoir of nutrient-rich water. [1] Because it is a non-circulating technique, no additional inputs of water or nutrients are needed after the original application, and no electricity, pumps, or water and oxygen circulation systems are required.

Azolla is a highly productive plant. It can double its biomass in as little as 1.9 days, [13] depending on growing conditions, and yield can reach 8–10 tonnes fresh matter/ha in Asian rice fields. 37.8 t fresh weight/ha (2.78 t/ha dry weight) has been reported for Azolla pinnata in India (Hasan et al., 2009).

The Summary. Increasingly frequent and severe heat waves in the Southwest are damaging some desert plants known for thriving in harsh conditions.
