The effects ofearly and late defoliations were evaluated under different levels of soil water content on root growth, appearance and disappear-ance in Stipa claraziiBall, S. tenuisPhil., and S. gynerioidesPhil. Field studies were conducted in 1995, 1996 and early 1997. Stipa clarazii and S. tenuisare two important palatable perennial tussock grasses in temperate, semiarid rangelands of centralArgentina, where S. gynerioidesis one of the most abundant, unpalatable perennial grass species. We hypothesized that (1) rootgrowth is reduced after defoliation at any phenological stage in S. claraziiand S. tenuisin comparison to undefoliated controls, (2) root growth, and root appearance and disappearance in all three species decrease...
