Growth of Lawn When Studied with Regard to Photosynthetic Rate and Formation of Ethylene-Effect of Treading

Abstract

The purpose of this study is to verify the growth of lawn in relation to treading as part of an investigation conducted to discover the capacity of a stretch of turf on a physiological level. A number of findings were collected. What is noteworthy here is the results of an experiment in which pressure was applied to lawn by treading on it 15 times a day for a period of 30 days in succession; a control was prepared for comparisons. It was found that the growth of lawn, if treaded on, will be suppressed significantly; the growth of the stem and leaves in terms of their length was hindered, if not prevented all together. The photosynthetic rate, moreover, dropped to half that of the lawn used as the control. It was later found that the limited growth of the stem and leaves was due to the work of ethylene being formed by the pressure on the lawn.
