all tested in the sawdust-filled bench (outdoors) with constant mist. The 

 results of these experiments are summarized in Tables 6 and 7. It is shown 

 there that cuttings of M. robusta responded with a higher percentage of

rooting than those of hazel-filbert. Some advantage is shown for growth 

 regulator treatments, except for that in dry powder form (Hormodin No. 3). 

 It is evident that these methods can be used successfully on other woody 

 plants besides sugar maple. 



That there is a definite advantage in taking cuttings from the terminal 

 position over those in the lateral position w^ith M. robusta No. 5 is shown 

 in the summary for two years results in Table o. The limited tests on two 

 clones of apple in 1958 I Table 9) indicate that rooting by M. robusta No. 

 5 was better than that of N. H. .55 stock.
