Table 5. Biomass partitioning in Triticum dicoccoides and Hordeum bulbosum plants taken at the end of the growing season in 1991 and 1992 from grazed paddocks at different stocking rates: H (heavy), 0.83 cows/ha; M (moderate), 0.5 cows/ha; and C (control), ungrazed.

^†The means of the significant differences were separated using the Tukey hsd (honestly significant difference) test (P < 0.05) from the SAS Institute (1985). Nonsignficant (or derived) differences have been left unmarked. Values followed by different letters are significantly different.

^‡Reproductive fraction is spikes/total biomass for T. dicoccoides and (spikes + corms)/total biomass for H. bulbosum.

^§ Corm fraction is corms/(spikes + corms).
