Spiral grain in trees is formed during the process of cell division and maturation within the vascular cambium (sensu lato). Much effort in the past half century has been put into elucidating the mechanism(s) involved. The most accepted view is that the dominant factor involves the pseudotransverse cell divisions during anticlinal (multiplicative) division and subsequent intrusive growth of the daughter cells, the slant of the partition (S or Z) and the direction of the intrusion being… CONTINUE READING
