Drought stress leads to plant death and damaged photosynthesis efficiency.
A study looked at how a type of bamboo plant called Pleioblastus kongosanensis f. aureostriaus responds to drought stress. The researchers found that the plant showed signs of damage after 17 days without water, and eventually died after 43 days. When watered again, the plant didn't fully recover. The plant's ability to photosynthesize and its chlorophyll levels were affected by the lack of water. The plant's leaf transpiration rate and stomatal conductance decreased as the drought stress increased. The plant's photosynthetic efficiency dropped significantly after 25 days without water. The study suggests that this bamboo plant grows best in soil with at least 12% moisture and can only withstand drought for up to 25 days.
