Summary

The infection of root hairs and nodulation ofT. subterraneum L. cv. Cranmore byRhizobium trifolii strain TA1 was extremely sensitive to root temperature. Within the range 11°–19°C infection was progressively delayed as root temperature decreased but at 7°C no root hairs were infected by 40 days. At 7°C lateral root formation was stimulated in the root zone where nodules formed at 19°C.
