Rhizophagus intraradices: matrix comparison of the spore shapes in relation to the host plant used for subcultures (two strains, ATT 4 and ATT 1102, combined). Results of Chi square tests are expressed with the X² value, and its significance level (*** when P ≤ 0.001; ** when P ≤ 0.01; * when P ≤ 0.05; NS when P > 0.05).
