I find with the banana varieties I grow, that when the air temp is 32-38°C (90°'s F) misting with water several times during the day & insuring the soil is not dry the plant grows fine. But ... when the air temp is above 38°C (100%deg;F) the leaves will fold up regardless of water. The plant goes into a self preservation mode (dormant??) to retain water. ... So I just don't see air temp over 38°C desirable for bananas nor the 50%deg;C (122%deg;F) in the propagation boxes ... Can you please post a link to the C.A.R. reference?

Just watch the banana leaves when the temps are high. Open, the plant transpiration is good. Closed & folded leaves indicates transpiration has stopped and the plant is over-heating.
