using this method , 5-au-induced inhibition , we have confirmed that in v. faba lateral roots there are two populations of dividing cells : ( a ) a fast-dividing population , which makes up approximately 85 % of the proliferating cell population and has a g ( 2 ) + mitosis/2 duration of 3.3 hr , and ( b ) a slow-dividing population , which makes up approximately 15 % of dividing cells and has a g ( 2 ) duration in excess of 12 hr .
