A proposed mechanism for physical dormancy break in seeds of Ipomoea lacunosa (Convolvulaceae)

摘要

Background and AimsThe water-impermeable seeds of Ipomoea lacunosa undergo sensitivity cycling to dormancy breaking treatment, and slits are formed around bulges adjacent to the micropyle during dormancy break, i.e. the water gap opens. The primary aim of this research was to identify the mechanism of slit formation in seeds of this species.
