A study looked at how different levels of water affected the growth of Camellia petelotii seedlings. They found that severe drought stress caused the plants to die, with 50-55% soil water content being the critical point. As the drought increased, the plants' ability to photosynthesize decreased, leading to damage to their photosynthetic apparatus. The levels of chlorophyll and other important compounds in the leaves also decreased with drought stress. Overall, the study showed that Camellia petelotii is very sensitive to lack of water, which can limit its ability to grow and spread.
