| Abstract/Contents: | "The influence of five light regimes during the period just prior to ear emergence until anthesis on Poa ampla, three P. pratensis biotypes and on the seedling progenies of an incomplete diallel cross between them, was examined. Both photoperiod and total irradiance affected seedling characters, their variances and dispersions, but the direction and magnitude of response differed between biotypes of P. pratensis. Results from P. ampla indicated that a higher proportion of amphimictic seed matured after 10-h photoperiodic treatments than after 20-h treatments. Biotypes differed in their response to light regimes in the period before and after ear emergence. The pollen parent and the interaction between pollen parent and light regime also affected seedling characters and their variances. Canonical analyses of discriminance were used to investigate interactions between seed parents, pollen parents and light regimes. The results are disussed in relation to different stages in apomictic seed production." |
