  • descriptionAbstract

    The effect of temperature and seed size on germination in Quercus rugosa Née was analyzed. Germination capacity and germinative energy were studied in three seed sizes: large (3.09 cm long by 1.55 cm wide, on average), medium (2.45 cm long by 1.29 cm wide) and small (2.15 cm long by 1.18 cm wide). Two day/ night temperature regimes in a controlled environment chamber were used: 24/19 °C and 19/14 °C, both with a 12 h photoperiod. A randomized complete block experimental design was used with six replications. The blocks were nested within the temperature factor. Germination capacity and germinative energy were analyzed with an analysis of variance using a mixed model. Seed size significantly influenced (P=0.0009) germination, with the large seeds having the highest germination. For germinative energy, the interaction between the two factors under study was significant (P=0.0045). The highest germinative energy was found in the medium-sized seeds at high temperature.

    Keyworks: Seed analysis, oaks, germinative energy.
