The duration of pre-chilling, the temperature, the provenance of the population, and the interactions between these factors significantly affected the MGT (Table 7). The average mean germination time varied according to the different periods of pre-chilling. The lowest rate and fastest speed of germination occurred after 2-w and 6-w of pre-chilling, respectively. In this study, we saw that temperature had a large effect on germination speed. As the temperature increased, the germination accelerated. Therefore, the lowest rate and fastest speed of germination occurred at 12 °C and 24 °C, respectively. The plotted curves (Figure 6) clearly show that germination occurs at a faster rate with increasing temperature and with increased duration of pre-chilling. The average germination speeds also greatly varied according to the seeds’ provenances. MGTs were 7.7 d, 11.9 d, and 16.1 d for Saimbeyli, Kozan, and Bucak, respectively. Discussion Rasprava Abies species demonstrate great variation in terms of seed weight. A. cilicica has the largest seeds (both in terms of weight and dimensions) among the Abies genus (Young and |
