1 Notes: ns=not significant. aGalls Index based on Taylor and Sasser (1978): 0=no galls; 1=1 to 2; 2=3 to 10; 3=11 to 30; 4=31 to 100, and 5=more than 100 galls per root system; breproduction factor=final population (PF)/initial population (Pi=5,000); cmeans followed by the same uppercase letter in a row and lowercase in a column, not differ significantly by the Scott-Knott test at 5% probability.
