Abstract Hand planted seeds of the mistletoe
Alepis
flavida establish much better on small
Nothofagus solandri branches
(<5 mm diameter: 48.4% establishment after one year) than on large
branches (20-30 mm: 6.1%), whereas intermediate sized branches have
intermediate establishment rates (10 mm: 21.6%). Wild 1-4-year-old
Alepis flavida seedlings occurred on branches 0.5-6 mm diameter
(mean = 1.9 mm). There was no significant difference in original branch
size between tagged mistletoe seedlings that died and those that lived, but
Alepis flavida shoot extension was positively correlated with host
branch diameter increment. These data suggest the early establishment and
survival of
Alepis flavida seedlings is strongly dependent on the size
and vigour of the branch on which the seed has been deposited.
