Moisture content, temperature, and relative humidity influence seed storage and subsequent survival and germination of Vallisneria americana seeds

摘要: Abstract Loss of aquatic plant species has occurred in coastal and freshwater habitats throughout the world. In particular, population habit loss submerged species, Vallisneria americana Michx., have made it a potential restoration candidate. For successful restoration, reliable seed sources are vital for producing plants or direct seeding. Seed survival their ability to retain viability through storage key components reproduction. subsequent germination V. were studied over 6-month period determine conditions that vigor. Seeds stored at three humidity levels 11%, 50%, 95% using saturated salts ambient 1, 2, 4, 6 months either cold temperatures. After intervals, moisture content, embryo viability, determined. Timing analyzed semi-and non-parametric analyses. Storing seeds lower RH longer periods reduced resulted later germination. Germination increased higher relative led earlier from northern Gulf Mexico shown be desiccation tolerant orthodox characteristics.
