Abstract
An intermediate stationary stage in the germination of Queensland blue grass (Dicanthium sericeum L.) caused by limiting water availability was examined. It was found that partially germinated seed can maintain viability over extended periods of desiccation and that large numbers of these partially germinated seeds are found under simulated and actual field conditions. Results indicate that this phenomenon is an adaptive mechanism which assists establishment on black cracking earths in which rapid drying of surface layers is characteristic.
