Abstract/Contents: | "At six positions on the lawn turf color was measured using the luminometer method and the fractionating light photometer method. Lawn light reflectivity (x: %) and chlorophyll content (y: mg/g) showed a very marked negative relationship, statistical analysis giving a linear regression equation of y=6.46-0.97x, r**= -0.9785. Through comparing the average coefficient of variation of light reflectivity (5.63) with the average coefficient of variation of chlorophyll content (6.49) it can be seen that compared with the fractionating light photometer method, the luminometer method is not only simple and quick, but is also more accurate." |
