Transpiration rate is low with poor airflow because water vapor accumulates around the leaf, reducing the concentration gradient and diffusion rate.
Le taux de transpiration est faible en cas de faible flux d'air car la vapeur d'eau s'accumule autour de la feuille, réduisant la différence de concentration et donc la diffusion.
| Front | Why is transpiration rate low around poor airflow? |
|---|---|
| Back | If air flow around a leaf is poor, the water vapour srrounds the leaf and doesn't move away. This means there is a high concentration of water particles outside the leaf as well as inside it, so difffusion doesn't happen as quickly. |
