Can a post-harvest ripening treatment extend the longevity of Rhododendron L. seeds?

Hay, F., Klin, J., and Probert, R. Scientia Horticulturae 111 (1):80-83. 2006.

Pre-dehiscent capsules were collected from two Rhodadendron griersonianum (Bali f. Forrest) trees and either immediately dried in a dry-room (15% relative humidity. 15 C) or placed in a high humidity room (80% relative humidity, 15 ºC) for 30, 60, or 90 d. Further capsules were also collected from the trees at 30 and 60 d, but seeds had been dispersed by 90 d. Seed aging experiments (60% relative humidity, 45º C) carried out on these seed-lots and on seeds from a further 10 Rhododendron species confirmed that short seed lifespans is a trait of the genus, with a mean P50 value of ca. 20 d for this storage environment.
