The lowest percentage of NLA was achieved in the combination of ASM-mycorrhizas, while the spirulina treatment was the most affected Fig.

At 59 d post-transplant, all treatments were inoculated with a mixture of four Cuban pathogenic isolates of A. Comparing the effects of the treatments at 10d, the ASM-mycorrhiza combination induced significantly higher level of enzymes than the worst treatments control and spirulina-mycorrhizas.

The increase in enzyme activity and protection against the pathogen were minimal in the spirulina and control treatments. In fact, ASM-mycorrhizas was the only treatment that markedly but not significantly differed from five of the total seven treatments, considering the NLA.
