Experimental design to determine global curvature. The global curvature was determined by drawing a tangent between the base and the apex of the stem. Two points, A and B were then chosen on the stem and tangents drawn through these points with regard to the horizontal. The angle between the tangent and the horizontal was then measured. dl is the distance between A and B, following the curve of the stem and is the difference of angles between the tangent at A and the horizontal and the tangent at B and the horizontal.
