Values are the mean of four replications. Values followed by the asterisks (**, in Sig column) in a row for tissue colonization% or ratings are significantly different according to Fisher’s protected least significant difference (LSD) test (P = 0.01), ns = not significant.
1Rating: 0 –no colonisation, 1 –highly restricted colonisation, 2 –sparse colonisation <10%, 3 –distributed colonisation, 4 –colonisation greater than 50%, 5 –extensive profuse colonisation. The scores were averaged across four plants.
