Seed germination of Phleum sardoum

What is it about?

Phleum sardoum is an endemic psammophilous species of Sardinia, growing exclusively on coastal sandy dunes. The effect of glumes on seed germination, germination requirements at constant (5–25°C) and alternating (25/10°C) temperatures, both in the light (12/12 h) and in the dark were evaluated, as well as the effect of a dry after-ripening period (90 days at 25°C), the salt stress effect (0–600 mmol NaCl) and its recovery on seed germination.

Why is it important?

Phleum sardoum (Poaceae) is a psammophilous species endemic to Sardinia. The only data available on seed germination of this species is reported in the Seed Information Database, which reports high germination percentages at 15°C and 20°C, with 8 h of irradiance per day, after removing seed covering structures. However, no factorial germination experiments were carried out on seeds of this species to determine the key factors in stimulating germination and to test the effect of the glumes.
