The Accuracy of Measurement the Surface of Silver Fir
(Abies alba L.) crown projection


Summary


The crown projection of silver fir is approximated by circle and ellipse and
their surface are calculated on eleven ways. This eleven methods are statistically
tested by Bartlett test of variance homogenity. It is found that the most convenient
method of measurement the surface of crown projections is by measuring two
perpendicular diameter of crown and the calculating the surface of ellipse by them.
