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.

SummaryAn analysis of chickpea experiments carried out in northern Syria during the 1980–1 and 1981–2 growing seasons showed that both intercepted solar radiation and its rate of conversion to dry matter were variable components of dry-matter production. Among the sources of variation in the experiments, the most important factor affecting both interception and utilization of solar radiation was site. Winter planting also led to increased solar radiation interception and utilization. Used in conjunction with chickpea lines resistant to blight, winter planting seems likely to lead to increased productivity. In higher rainfall areas, where the crop is usually grown, such an increase would be of commercial significance. In drier areas, winter planting would enable the cultivation of chickpea as a subsistence crop.
