Low temperature limits for root growth in alpine species are set by cell differentiation

This paper explores the causes of plant growth cessation at critically low temperatures in arctic-alpine environments. We grew four alpine plant species in thermostated soil cylinders in the field in the Swiss Alps, monitored root growth and studied root tip anatomy. Roots stopped growing at tempera...
