Abstract
Anthyllis hermanniae L. (Fabaceae) is an evergreen pollinator-friendly shrub, resistant to the harsh Mediterranean environment, proposed for sustainable landscaping.
Aiming to introduce this species into the horticultural industry, in May 2014, plantlets produced from autumn stem cuttings and micropropagated plants were transplanted on a peat-perlite (2:1, v/v) substrate and were fertilized once a month with 2 or 4 g L‑1 water-soluble complete fertilizer (Nutrileaf 60, 20-20-20) or on a substrate of enriched peat-perlite (2:1, v/v), without fertilization.
In November 2014, plantlets produced from spring cuttings received the three abovementioned treatments, while plantlets from micropropagated plants and seedlings were transplanted only on a peat-perlite (2:1, v/v) substrate and were fertilized once a month with 4 g L‑1. Plantlets from autumn cuttings and micropropagated plants, which were cultivated in the same treatments during May to August 2014 period, had similar response forming equal number of main shoots, while length of main shoots and number of lateral shoots per main shoot or plant were greatest in the peat-perlite 2:1 (v/v) substrate, with fertilization 4 g L‑1 per month, followed by fertilization with 2 g L‑1. In the second experiment, which lasted from November 2014 to February 2015, plantlets from spring cuttings showed similar response in all growth parameters, independently of substrate and fertilization, while micropropagated plantlets were lacking regarding the length of main shoots.
Although plantlets from seedlings formed less main shoots, they produced the most lateral shoots per main shoot, resulting to equal number of lateral shoots per plant to plantlets from cuttings.
In conclusion, A. hermanniae plantlets of the three origins (rooted cuttings, micropropagation, seedlings) grew satisfactorily in greenhouse conditions, after transplantation on peat-perlite (2:1, v/v) substrate and monthly fertilization with 2 or 4 g L‑1, showing that they could all be used efficiently as source of plants for commercial horticulture.
