Comparisons of Three Scales of Measurement of Creeping in Alfalfa1

Abstract

Abstract

Percentages of plants creeping, visual estimates of spread of individual creeping plants, and measurements of spread of both creeping and noncreeping plants were compared as scales of measurement of creeping-root development in alfalfa. In Experiment I, the scales did not differ significantly in power to detect differences in creeping among the lines. In Experiment II, percentages of plants creeping and measurements of spread were equally sensitive, and both scales were more sensitive than visual estimates of spread.
