On sandy soil of low K availability, permanent pasture cut 5 times during the year received up to 200 kg/ha K2O as 40% KC1 before or after one of the cuts. The effect of K fertilizing in autumn depended largely on K withdrawal with previous cuts. K uptake was not determined by growth. Except for the first cut K uptake was greater than that needed for reasonable growth. No effect of temperature on K response was found. The best treatment was 200 kg/ha K2O applied in spring.

Nineteen accessions of elephant grass (Penniseturn purpureurn) were grown in a long-day photoperiod at 5/10, 18/13, 21/16, 27/22, 33/28 and 36/3l�C day/night temperatures during spring, summer and autumn in the Canberra phytotron. The temperature optimum for dry matter production was 33/28�C, and the magnitude of dry matter production was dependent on the solar radiation received; the low radiation levels in autumn reduced yields of advanced plants. Except at the lowest temperature, cumulative yield was associated with cumulative radiation. Rate of stem elongation was highest at 33/28�C under the spring and summer radiation regimes. Under autumn radiation conditions, rate of elongation was highest at 27/22�C. Rate of leaf appearance and leaf area per plant were linearly related to temperature and were little affected by radiation level. Rate of tiller production showed two maxima, at 18/13-21/16�C and at 33/28-36/31�C, and the maximum temperature was dependent on radiation level. The accessions Q5083, Bana grass and Taiwan consistently produced high yields throughout the range of temperatures tested. The results are discussed in relation to accession performance in the field.

Bud dormancy was induced in Douglas-fir seedlings 90 days after seed germination. Dry matter production of bud-dormant plants was determined for a 7-week growth period at five controlled temperatures from 2 to 24 °C. There was no significant temperature effect between 7 and 24 °C on total dry matter production, which at 2 °C was reduced. Dry weight of the root was affected more by temperature than that of the plant top. A pronounced temperature effect on dry matter production was found previously between 13 and 18 °C for plants in the stage of leaf production. This did not occur for bud-dormant plants because temperature effect on leaf production was not present. Net assimilation rates during bud dormancy were generally lower than during the stage of leaf production, especially at low temperature. This may have been caused by a reduced "sink" for use of photosynthates during bud dormancy.
