For measurement of spore germination rate of C. gloeosporioides, aliquots of 100 L of spore suspension at 1 × 109 L−1 were individually transferred to glass tubes with potato dextrose broth (PDB), which contained SNP concentrations at 0 and 0.1 mM. All the tubes were put on a rotary shaker at 1.7 s−1 at 25 ◦C and incubated for up to 12 h. Approximately 200 spores were measured at 3 h intervals for germination rate per replicate, with 3 replicates for each treatment. The experiment was repeated twice.
