Engineers at the flooded plant, while waiting for help to arrive, had started to build homemade boats using office furniture and salvaged tsunami debris, using them to bring food to still-stranded townspeople.
Lack of oxygen has been suggested as main difficulty for plant [ 52], during the time and after the flooding plant may be affected by root rot disease which cause reduction of growth and loss of yield [ 52], also includes nitrogen deficiency of plant [ 53], or nutrient imbalance [ 54– 54].
Starch content and distribution was examined in fresh, free-hand sections taken up to 1 cm from the root tip of non-flooded roots and adventitious roots from flooded plants.
However, at all measured temperatures ranging from 10 °C to 30 °C, the hydraulic conductivity (LIND) of individual roots (20 – 30 cm long) was several-fold higher in non-flooded seedlings compared with adventitious roots of flooded plants.
Activation energy (Ea, kcal mol-1) for LIND was higher in adventitious roots of flooded plants (4.95 ± 0.5) compared with control non-flooded roots (3.25 ± 0.3).
Decreases in physiological measurements occurred by day 9 in freshwater flooded plants.
There may be emission of methane gases in dams when flooded plants are rotting in the water.
Floods can also temporarily close factories, as the monsoons in Thailand did when flooded plants were closed, and a shortage of hard drives in 2011 affected PC inventories.
Black willow showed a significant hydroperiod nutrient interaction wherein fertilizer increased stem and root biomass under drained conditions, but flooded plants did not respond to fertilization.
