The study looked at how different plants release water through their leaves, and how this is influenced by factors like temperature, humidity, and sunlight. They found that the amount of water released by the plants follows a specific pattern throughout the day, with the highest release happening in the afternoon. Temperature had the biggest impact on water release, followed by humidity and sunlight. Older plants released less water than younger ones, and the release varied throughout the year, peaking in June, July, and August. Overall, temperature was the most important factor affecting water release from the plants.
