摘要
Two red clover (Trifolium pratense L.) cultivars; Hokuseki and Merviot were surveyed growth habits and deterioration at the crown and taproot in the 3rd year. Each cutting plants were marked and measured the plant height and dry matter weight. After 3rd cutting of the 3rd year, plants were digged out and scored the degree of root rot and internal break down (no symptom: 0-severe damaged: 5). The severe damaged plants at the 3rd cutting tend to have larger plant size at the 1st cutting. And other root development traits during growth were observed.
