Abstract Four species of leguminous shrubs
endemic to the
Canary Islands (Spain)—Chamaecytisus palmensis (tagasaste),
Teline canariensis, Teline osyrioides sericea and Teline
osyrioides osyrioides—were evaluated from 1999 to 2000 as a source
of animal forage. Two experiments were undertaken. Experiment 1
involved wild populations in the natural habitat on the island of
Tenerife including germplasm collection and a study of their phenology.
Experiment 2 involved the same species, this time in cultivation with a
density of 5142 shrubs/ha on an experimental plot (La Laguna, Tenerife)
situated at 549 m a.s.l. and with annual rainfall of between 338
and 562 mm. Experiment 2 evaluated plant survival, edible green
matter/inedible matter fraction (EGM/IM) and production of edible dry
matter (EDM) at three cutting heights (30, 50, 70 cm above ground
level). Samples were taken at the end of each season during 2
consecutive years. Production of Chamaecytisus palmensis was
significantly higher (P < 0.05) at all three heights
than that of the three species of Teline, which had similar
productions to each other. However, cutting height did not affect EDM
production.
