Dormancy and Vigour of Tree Seeds
Leadem, C.L.
1988: Vernon, CAN
This paper discusses tree seed dormancy and vigour with specific references to the true firs (Abies). The benefits of a modified stratification method the stratification redry technique are outlined. Physiological measurements are described with some examples of how they may be applied to assess seed vigour. Especially promising for the development of seed vigour indexes are low temperature stress tests, germination rates, seed respiration, and seed reserve levels. These may soon be employed as management tools to aid nurserymen to monitor the deterioration of seeds in storage, to assess the effectiveness of dormancy release treatments, and to predict seed performance in the nursery.
