Fig. 3. One percent indoleacetic acid in lanolin can substitute for the 

 axillaries in causing slower flowering (above), but cannot substitute with 

 respect to compensatory growth (below). (Data in Table II.) 



speed of flowering (Table II). (Remember, too, that axillary excision 

 did not speed flowering in such plants.) 



How Complete Is the Compensation? 



Small plants were divided into three matched groups and treated as 

 shown in Fig. 5. After 86 days of treatment, all remaining leaves were 

 excised and immediately weighed. Results are shown in Fig. 5. Despite 

 the striking increase in the growth of those leaves that remain in the 

 axillaries-off plants, the compensation is far from complete. Plants 

 showing compensatory growth have leaf weights totaling 60% of the 

 total leaf weight in the control plants with intact axillary shoots.
