This curve is a very typical one for a clear day at this position, in that there is a rapid rise in the morning to a high maximum, and a following clearly marked depression due to a saturation deficit, but no visible wilting occurs; then a second low mode in the afternoon about 4:00 , followed by a rapid decline with the closing of the stomata in the evening. The morning maxi- mum occurs from 9: 00 to 12: 00, unless disturbed in some way by.
