Title:
Bud banks of perennial savanna grasses in Botswana
Publication Year:
2006
Abstract:
Three semi-arid savanna grasses in Botswana (Stipagrostis uniplumis, Eragrostis lehmanniana, and Aristida stipitata) were sampled to quantify their belowground bud banks during the dormant season and to estimate their relative allocation to vegetative and sexual reproduction. Bud banks of these African perennial caespitose grasses were also compared with four perennial caespitose grasses of semi-arid North American grasslands. The three African grasses each maintained approximately two buds per tiller and showed a high percentage (88-99%) of tillers producing seed. Keywords: clonal plants, meristems, plant demography, reproductive strategy, vegetative reproduction.
