dc.description.abstractExcised ligulae of Glossophora kunthii from central Chile were cultured at temperatures of 5-25.degree. C, photoperiods of 16:8 and 8:16 h LD cycles, with photon irradiances of 10 and 50 .mu.mol .cntdot. m-2 .cntdot. s-1. Growth of the ligulae, number of fertile ligulae and number of tetrasporangia forming on the ligulae were assessed. Ligulae tolerated temperatures between 10 and 23.degree. C. Temperature interacted with daylength and photon dose, determining quantitative responses in the growth and fertility of ligulae. Growth was least at 8:16 h LD and was not affected significantly by temperature. It was greatest at 16:8 h LD, 50 .mu.mol .cntdot. m-2 .cntdot. s-1 and increased with temperature up to 20.degree. C. Percentage of fertile ligulae and number of tetrasporangia increased with temperature at the 8:16 h LD cycle, reaching a maximum at 20.degree. C. Fertility was low at 16:8 h LD, except at 20.degree. C (and low photon dose) suggesting that reproduction at 20.degree. C is independent of daylength in this species. Ligulae grew larger at the lung-day photoperiods and the proportions of fertile ligulae were higher at the short-day photoperiods, irrespective of the total photon dose received. These results suggest that some aspects of growth and fertility are controlled by photoperiod.
