Abstract
Abstract Laboratory studies using seed of Leptospermum seoparium J. R. et G. Forst. collected from tagged trees in the Waitakere Ranges near Auckland showed that there was a low overall germination percentage but substantial variation in germination from tree to tree. Germination rate but not final percentage was affected by temperature and by alternating periods of dehydration WIth periods of adequate availability of water. Only a very low total incident radiation was necessary for germination but germination was reduced 10 the dark. It is probable that the low germination percentage is a result of a high proportion of non-VIable seed. There was no evidence of dormancy and, in the Auckland region, it is likely that the major ‘seed bank’is present in the unshed capsules rather than on the ground surface.
