Some considerations in the planning of toxicity tests and in the reporting of results are discussed. The need for using standardized stocks of fish and standardized data recording and data reporting procedures is argued. Standardized sheets for repor

Samples from six cultivars of subterranean clover (Trifolium subterraneum) were harvested at two stages of maturity (vegetative and senescent) and one cultivar (Dinninup) at two additional stages. The samples were freeze dried to 90% dry matter, cut

On sandy soil near Esperance, W.A., prevention of burr burial compared with covering developing burrs with sand drastically reduced the seed production of three subspp. of Trifolium subterraneum (brachycalycinum, subterraneum and yanninicum) and of T

Single plants of subterranean clover (Trifolium subterraneum) were grown from seed of 13 commercial Seaton Park seed samples and of five pastures sown to Seaton Park at least 8 years previously. Most populations had several variants of Seaton Park, t

Swards of three strains of subterranean clover (Seaton Park, Yarloop, Midland B) were subjected to a range of defoliation treatments. In all strains, cutting at weekly intervals at a height of 1.5–2 cm from 1 month after sowing until the onset of f

The number and weight of seeds per unit area, and weight per seed were measured for single seed crops of 6 subterranean clover cultivars grown as dense single strain swards on sandy soil near Esperance, W.A. In the sowing year, weight and number of s

An experiment was conducted in a glasshouse to study the effects of withholding water during flowering on seed production in subterranean clover. Two strains, Northam A (long duration of flowering) and Geraldton (shorter duration) were grown as sward
