INOCULATION OF EASTERN WHITE PINE WITH BLISTER RUST 385 



PATTON: As panel leader I note that we're already 10 mintues overtime, 

 so I think it best that we move on to the next paper. However, there will 

 be an opportunity to discuss these inoculation techniques while we're in 

 the Intermountain Station blister rust nursery this afternoon, 3 and also 

 later on. Let's continue with the last paper on this morning's panel. 



3 Editor's note: Informal nursery discussions later this day brought 

 suggestions that test materials inoculated in the primary -foliage stage 

 might react differently than those inoculated at the 2-year-old 3 secondary 

 foliage stage — -possibly due to anatomical or physiological differences of 

 first- vs. second-year foliages } or to resistance factors differing between 

 the 2 ages of foliage.
