Potential Propagation by Seed and Cuttings of the Azorean Native Calluna vulgaris (L.) Hull

Table 3

The effect of storage period at room temperature on the germination characteristics of Calluna vulgaris seeds under a photoperiod of 8 h and a temperature regime of 10°C. Mean values ± standard deviations. In each column, groups that showed significant differences (𝑃<0.05) are indicated with different letters.
