Abstract
In the context of biosourcing from biodiversity for new ornamental crops, the aim of the present study was to investigate the effect of incubation temperature on seed germination of the attractive Linum arboreum L. (Linaceae), a Greek native Aegean subendemic subshrub.
The germination responses of wild-sourced seeds were evaluated at four constant temperatures of 10, 15, 20, and 25°C using temperature-controlled growth chambers with a 12-h light/12-h dark photoperiod, and the natural species’ requirements were explored with geographic information systems (GIS) based on its distribution range.
The results of the germination test showed that seed germination was affected by incubation temperature.
The seeds incubated at 10, 15 and 20°C germinated at high percentages (89.17, 96.67 and 94.17%, respectively), and no significant differences were observed among them.
The lowest germination percentage (15.83%) was observed at the high incubation temperature of 25°C. Τhe GIS-derived ecological profile provided important information regarding the climate conditions (temperature, precipitation) under which the studied species grows in its natural habitat, and facilitated the interpretation of the effect of temperature on seed germination, also informing for the appropriate conditions regarding its use as an ornamental plant in man-made environments.
The knowledge of the germination requirements of L. arboreum seeds will facilitate conservation efforts and may contribute to its sustainable exploitation as a new native crop of ornamental value.
