“…There was no difference between Roa and S170 in production or acceptability to animals, as sheep satisfactority grazed both cultivars. Differences in acceptability reported by Anderson et al (1982) may have been masked by the buffering effect of the large proportion of volunteer grasses present.…”

Grasslands Roa' and S170 tall fescues (Festuca arundinacea Schreb.) were compared with 'Grasslands Ruanui' perennial rye grass (Lolium perenne L.) for 2 years in pastures grazed by sheep. During the first year, pastures were close-grazed at 2 frequencies (3-and 6-week), but in the second year at one frequency (3-4 weeks) with 2 intensities (down to 3 or 8 cm). Over the dry summer-autumn period, tall fescue was superior to ryegrass i.n both quantity and quality of herbage produced, resistar,tce to wilting, and persistence. Dry matter productIOn of tall fescue was similar to ryegrass in winter, but poorer in spring. There was no difference i~ DM production between the 2 tall fescue culhvars. Clover contents were low particularly with tall fescue. Problems of establishment and early management of tall fescue are discussed.

“…Buenos Aires). In New Zealand, tall fescue has been recommended as an option where summer drought limits the persistence of ryegrass (Lolium perenne L.) (Anderson 1982;Anderson et al 1982;Brock 1982). The greater ability of tall fescue than other grass species to tolerate drought has been related to its higher root density at depth (Garwood and Sinclair 1979).…”

Two glasshouse experiments were carried out to evaluate the morphological and physiological responses to water deficit of Mediterranean and temperate tall fescue (Festuca arundinacea Schreb.) cultivars. In Expt 1, 3 cultivars were studied: 2 temperate cultivars, Grasslands Advance (GA) and El Palenque (EP); and a Mediterranean cultivar, Maris Kasba (MK). Water deficit was induced in containers of 4 plants of a single cultivar by withholding water. In Expt 2, plants of EP and MK were grown together in the same container and received water daily with gradation in intensity of water deficit achieved by varying the daily water ration per container.All cultivars in each experiment exhibited commonly reported responses to water deficit, characterised by diminished evaporative surface area and increased root : shoot ratio. The response of MK was primarily morphological and MK plants had smaller plant size, higher root : shoot ratio, and a lower growth rate compared with temperate cultivars. By contrast, response of temperate cultivars was primarily physiological; stomatal conductance of temperate cultivars was lower and these cultivars had a greater tendency for leaf lamina osmotic adjustment than MK under the most stressful water deficit conditions studied. The morphological adaptations of MK were very effective in delaying the onset of water deficit in Expt 1 when plants were grown with others of the same cultivar, but rendered MK plants uncompetitive and more susceptible to water deficit in Expt 2 where plants of MK where interspersed with plants of a temperate cultivar.Additional keywords: plant water relations, roots.

“…Anderson et al (1982) found that the hypomagnesaemia ratio, K/(Ca + Mg), was wider in Roa tall fescue than in Ariki long-rotation hybrid ryegrass. Sleper et al (1977a) showed heritable variation for the ratio and for the elements separately.…”

Tall fescue in Australia and New Zealand

Tall fescue is widely naturalised in Australia and New Zealand. Its use in pastoral agriculture has developed with the availability of suitable cultivars. Naturalised tall fescue is infected with Acremonium endophyte and is known to be toxic. The significance of endophyte is briefly discussed. Tall fescue can be slow to establish after sowing, and palatability is sometimes inadequate. Greatly enhanced winter growth, through the use of Mediterranean germplasm, would extend use of the species into more summer-dry environments. Research supporting these and other objectives is reviewed. Current breeding programmes in Australia and New Zealand are described.
