Research Articles

Accelerated Germination by Osmotic Seed Treatment Heydecker et al. 1973 Research Article

Osmotic pretreatment of seeds increases the rates and uniformity of germination.

"The combination of -10 bar and 15 C for 11 days, however, was nearly as successful in increasing the rate of germination of the seed population as the best treatment."

Methodology

The Osmotic Potential of Polyethylene Glycol 6000 Michel et al. 1973 Methodology

The data were found to fit the following equation:

Ψ = -(1.18 × 10^-2)C - (1.18 × 10^-4)C² + (2.67 × 10^-4)CT + (8.39 × 10^-7)C²T

Ψ

Osmotic potential (bar)

C

Concentration PEG-6000 (g/kg H,O)

T

Temperature (°C)
