fennia-3860	Tuovinen, Mervi; Jalkanen, Risto; McCarroll, Danny	The effect of severe ground frost on Scots pine (Pinus sylvestris) trees in northern Finland and implications for palaeoclimate reconstruction	2005	12	.pdf	application/pdf	5194	310	68	Since it is known that there were differences in the canopy reaction of young (45 years in average) and mature (130 years in average) pine trees (Jalkanen et al. 1995), they are considered separately. The effects of the winter frost were very obvious in the summer of 1988, with widespread defoliation of pine trees of all age classes, so it is remarkable that there is almost no effect on the measured tree ring parameters from the mature trees.	cache/fennia-3860.pdf	txt/fennia-3860.txt
