The Effect of Relative Air Humidity on the Development of Water Saturation Deficit in the Cut Leaveswater deficit occurs most often on warm sunny days when all other factors, such as light, temperature and CO., are very favourable for high net photosynthesis. Under these conditions — relatively small change in water deficit can lead to relatively big changes in photosynthetic rate.

Water Stress in Conifers During Winter If these changes should exceed a comparatively moderate range, the needles would die. Since most of them do survive after all, we are faced with the problem of how they may avoid excessive water loss.

The Effect of Decrease in Soil Moisture on the Osmotic Values of Cell Sap in the Individual Organs oaves, petioles and stems, under the influence of changed soil moisture. In order to make the necessary number of analyses in the required time the methods of the experiment were slightly modified as against those used in the previous work.

Serial Studies on the Hydration of Forest Plantsion of the individual factors of those properties can only be of practical use if a great талу of them are studied simultaneously. Therefore, applied plant physiology strives to investigate reactions and characteristics which essentially influence the properties of interest or result from a multitude of such individual factors.

Water Relations of Some Steppe Plants Investigated by Means of the Reversibility of the Water Saturaeached various degrees of water deficit. The measurements were made on segments of grass blades. We were able to establish two types of saturation curves, with a characteristic difference between them:

Changes in the Water Status in Plants Under Different External and Internal Conditionsing the division of water into these two fractions due to the absence of sharp boundary between them. The ratio of free and bound water depends upon the amount of the water-removing force applied (Tumanov 1940, Alekseev 1948) and is thus an arbitrary value.
