Growth and Persistence of Several Varieties of Red Clover at Various Temperature and Moisture Levels¹

Synopsis The size of red clover plants which grew under laboratory conditions was not directly correlated with persistence of plants of the same variety in the field. The smallest plants obtained in the controlled environment were of the most persistent variety. The varieties did not differ significantly when the plants were subjected to a frequent‐clipping treatment or prolonged incubation in a dark chamber.
