Fruit production by two species of privet, Ligustrum sinense Lour. and L. lucidum W.T. Ait., in Sydney.
Fruit production by Ligustrum sinense and L. lucidum was studied at 58 sites in urban bushland in the N. suburbs of Sydney in 1978, and in a further 8 sites (L. sinense) in 1979. L. sinense produced 1300 fruits/m2 of canopy while L. lucidum produced 400/m2. Fruit production in both spp. was reduced with increasing shade and was lower on smaller diam. shoots of L. sinense. There was variation in fruit production between shoots of similar sizes and at different sites which was not correlated with soil fertility. Sites with high L. sinense fruit production in 1979 were not the same as those with high production in 1978.
