Abstract

Seed germination reports for five coastal and inland species from the Maltese Islands

Highlights

  • We present seed germination results for five different indigenous species occurring in the Maltese Islands

  • The highest percentage of 90% was at an alternating thermoperiod of 23.5/15°C under full dark conditions, though a 16/8 photoperiod gave good germination results (85%) indicating that seeds are not negatively affected by light

  • Further studies on seed conditioning, seed viability as well as fungal associations occurring during germination are envisaged

Summary

Introduction

Based on Sommier & Caruana Gatto (1915), Borg (1927), Haslam (1969), Haslam & al. (1977), Pignatti (1982), Lanfranco (1984, 1995), Lanfranco & Schembri (1986), Anderson & Schembri (1989), Schembri (1994, 1997), Savona-Ventura (2001), Casha (2015, 2020), the flora of the Maltese islands, including the autochthonous and allochthonous ferns and spermatophytes, amounts to about 1100 taxa, species and subspecies. With regards to seed germination studies of the indigenous plant populations very little is known. We present seed germination results for five different indigenous species occurring in the Maltese Islands. The five species selected are indigenous elements of the Mediterranean flora from similar coastal and more inland habitats. Three of the species considered are coastal and more inland elements and include Drimia maritima (L.) Stearn, Periploca angustifolia Labill., and Asparagus aphyllus L. The remaining species, namely Pancratium maritimum L., occurs on sand dunes which in the Maltese Islands are severely limited
