Differences in Arbuscular Mycorrhizal Fungi among Three Coffee Cultivars in Puerto Rico
Figure 2
Abundance (number ) by morphotypes of AM fungal spores associated with coffee cultivars at Serrallés farm. For each cultivar the sequence of bar represents seven spore morphotypes: yellow globose, yellow ovoid/ellipsoid, brown globose, brown ovoid/ellipsoid, brown elongated with narrow base (i.e., Sclerocystis), white ovoid/ellipsoid, and white globose. Chi-square tests for independence showed significant difference in morphotype distribution among cultivars (; ). Error bars show +1 s.d.
