The Effect of Long Term Stratification on the Germination of Pinus Pinaster Ait

SYNOPSIS

Trials to determine the effect of long term stratification on Pinus pinaster seed subjected to periods of room temperature storage following cold storage and cold storage only indicated that the former could reduce viability of the seedlots. Dormancy of all the seedlots tested was significantly reduced by six to seven months stratification, the results being much more consistent than the 60 to 90-day treatment currently prescribed.
