Zephyra compacta is a geophyte plant endemic to Chile with the potential to be used as an ornamental crop. Its natural habitat is the coastal plains of the Atacama Desert, with a climate described as coastal desert with abundant cloudiness. This work analyzes the germination of Z. compacta seeds at 10, 15, 20, and 25 degrees C. Seeds were collected in 2011 and stored for 2 years and 4 months at 5 degrees C, until sowing. A mathematical model was used for germination analysis, p = A{1 - exp[-k(t - t(0))]}, where p is the germination percentage at a certain time t, A is the final germination percentage, t(0) is the estimated time of germination of the first seed, and k is the measure of the spread of the time to germination. Furthermore, the rate of germination of the median seed to germinate (1/t(A/2)) was included. The germination curves showed a coefficient of determination (R-2) between 0.86 and 0.99. The results show that temperature range for germination is from 10 to 20 degrees C, where A is over 90%. In this range, other evaluated parameters (t(0), k, and 1/t(A/2)) show no significant difference, with the exception of k at 15 degrees C. At this temperature, germination is obtained in a shorter period of time and could be considered as the optimal temperature within the range. Finally, 25 degrees C is a supraoptimal temperature, where the value of A decreased to 30%.
