The study looked at how different levels of soil water affect the growth of Camellia oleifera seedlings. They measured how much water the seedlings used and how well they were able to photosynthesize under different soil moisture conditions. The results showed that seedlings grew best when the soil moisture was at 80%-85% of its capacity. When the soil was too dry, the seedlings couldn't grow properly. The researchers found that the seedlings used the most water during the middle of the day. Overall, the study showed that the right amount of soil water is crucial for the healthy growth of Camellia oleifera seedlings.
