An analysis of variation of leaf characters in Quercus robur L. and Quercus petraea (Matt.) Liebl. population samples from Northern Ireland

, : An analysis of variation of leaf characters in Quercus robur L. and Quercus petraea (Matt.) Liebl. population samples from Northern Ireland. Irish Forestry 40(2): 52-77

Samples of leaves were examined from 1087 trees in 35 'populations' at 32 sites throughout N. Ireland. Hybrid ancestry was assigned to 145 trees (13.3%). Based on proportions of Q. robur, Q. petraea and hybrids, 8 population types were distinguished.

The polysaccharide isolated from 5 day old egg masses of B. glabrata is composed only of .beta.-D-galactopyranose residues. Methylation analysis of the methylated polysaccharide resulted in the detection of the following sugars: 2,3,4,6-tetra-(34...
