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

Table 7

The effect of substrate type on the rooting percentages of Calluna vulgaris heel cuttings harvested in March and planted outdoors. Mean values ± standard deviations. Groups that showed significant differences (𝑃<0.05) are indicated with different letters.

Substrate	𝑁	Percent rooting
Native soil	4 × 10	80.0 ± 10.0^a
Native soil : perlite (3 : 1)	4 × 10	95.0 ± 10.0^a
Peat : Perlite : vermiculite (2 : 1 : 1)	4 × 10	62.5 ± 9.6^b
Peat : perlite (1 : 1)	4 × 10	45.0 ± 12.9^c
