Abstract: | A single tropical plant species can harbour hundreds of endophyte species within its tissues. Beyond this, little is known
about the relationship between endophyte colonization, leaf traits and spectral properties of leaves. We explore these relationships
in Coccoloba cereifera, a plant well known for its symbiotic properties. Endophyte richness in C. cereifera was statistically correlated with leaf traits such as water content, the ratio of fresh weight/dry weight and polyphenol/leaf
specific weight. Endophyte diversity was also related to spectral vegetation indices of chlorophyll content. The associations
among endophyte diversity, leaf traits and spectral reflectance pose new questions and present new opportunities to better
understand plant–fungal symbioses and related leaf optical properties. |
