Sea water and its effects on Bambusa vulgaris (common bamboo)
The hypothesis is proven to be true. Watering bamboo plants with sea water causes a stunted growth or kills the plant.
Sea water is sometimes use to put out forest fires. It may help to put out fires but in turn, adversely affects the growth of the plants that survive the fire. It is advisable to use fresh water if it is available.
What would happen if the experiment was varied by using brackish water or water from freshwater lakes or ponds?
The experiment can be repeated using different plants such as bean sprouts, radishes and other fast growing plants.
