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

Table 1

The effect of light regime on the germination characteristics of Calluna vulgaris seeds at 15°C. Storage period at room temperature before trial: 6 days. Mean values ± standard deviations. In each column, groups that showed significant differences (𝑃<0.05) are indicated with different letters.
