The genetic improvement of Phalaris aquatica L. and its scientific basis are reviewed. The few accessions made in the 1890s gave rise to cv. Australian. Trumble selected ‘Gb81’ within ‘Australian’. Major collections in 1951 and 1954 gave cult

The improvement of grazing and drought tolerance of temperate (C3) perennial pasture grasses is an important component of plant improvement programmes. The improvement of these characteristics in grasses is best based on an understanding of the physi

summary The net mobilization of nitrogen compounds (total N, soluble protein, amino N, membrane-bound protein) from different plant parts after defoliation, and the extent to which mobilized nitrogen contributed to new leaf growth, were studied in sm

Small swards of white clover (Trifolium repens L.) cv. Haifa were grown in solution culture in a controlled environment at 24 °C day/18 °C night and receiving 500 μE m-2 S−1 PAR during a 14-h photoperiod. The swards were cut either frequently (1

Successful seedling recruitment events in sparse stands of the grass Phalaris aquatica (phalaris) are rare. A major contributing factor to this situation is the seed-harvesting activity of ants. In recently developed cultivars of phalaris, the seed i

Crosses were made between Australian and its seed-retaining, but inbred derivative, Uneta, to develop a vigorous, grazing-tolerant, seed-retaining phalaris cultivar similar to cv. Australian. Forty-two half-sib families from seed-retaining F 2 plants

Four cultivars of phalaris were evaluated for their ability to survive a severe drought in 1994 in an existing grazing experiment at 2 sites near Canberra. The effect of rotational grazing and set stocking on persistence of phalaris measured as basal
