Book Description
An investigation was made of major interrelated factors which influence the transfer of water from soil through plants to the atmosphere. Results are reported from three studies: (1) effect of temperature on relative vapor pressure of water in soil; (2) relation of psychrometric to membran us measurements of water in soil; and (3) evaporation from soil.

Book Description
The following advances in technology for measurement of water potential are described: (1) A thermocouple for direct attachment to plant leaves; (2) A microchamber for studying plant responses to environment is described. Light intensity and duration, ambient temperature, relative humidity, and CO2 concentration are controlled. Transpiration, CO2 assimilation, and plant and soil water potential are measured. Data for the ratio of transpiration to CO2 assimilation for cotton are given. Moderate salinity increased this ratio. Description of a contact closure distributor to make a data acquisition system serve as a control device as well as a recorder is given. Also described is a tape editor for handling output data from the system. Preliminary results from experiments to determine how plants integrate time varying salinity indicate that transpiration per unit leaf area is decreased by salinity. (Author).
