Sycamore (Acer pseudoplatanus), a comparison of seed sources


, : Sycamore (Acer pseudoplatanus), a comparison of seed sources. Gartneryrket 78(17): 528

Fourteen different seed sources from various parts of Norway were studied for height, hardiness and overall landscaping quality. The progeny of individual trees comprised half-sibling families. In 1983, several seedlings from each family were planted out at various sites, but no distinction could be made between genetic and environmental variations. The 4 most hardy lines came from Trondheim and Nordland.

The development of seeds of Norway maple and sycamore, from flowering to late maturation, was investigated in Poland. Maximum flowering of sycamore was 3 wk later than in Norway maple but the development of their seeds was faster. Sycamore embryos...

As main reasons for these low values in T. co...
