Changes in transpiration data in plants of the genus Solanum

Abstract

A study was carried out of the physiological parameters of the tomato variety “Barberry F1”, under the influence of an external factor, at night in the conditions of the Moscow region. Parameters such as transpiration were observed. According to the results of the experiment, there are significant differences between the two variants of the experiment (control and experiment). Under the influence of the limiting factor, there is a general increase in the efficiency of transpiration; in addition to the general increase, changes occur in the studied parameters under the conditions of dividing the plant into tiers. Thus, in the control plant, the middle leaves show significant differences from the upper and lower tier, whereas in the experiment this difference is significant only in some cases.
