Soil water content, soil strength and the growth of elm root suckers.

Abstract

The elongation rate of root suckers of Dutch elm (Ulmus x hollandica Mill.) increased with increasing age of the sucker, soil water content and net growth pressure (the excess of turgor pressure over soil restraining pressure) and it decreased with increasing soil strength. The increase in the rate of sucker elongation with age was probably the result of a… (More)
