Diversity Index Analysis of the Phyllosphere Fungal Flora of
Rubber Trees with Powdery Mildew
The fungal OTU statistics were analyzed at the 97% similarity level,
and the OTU numbers for the 16 samples ranged from 71–692. As shown in
Table S5, the Ace and Chao indexes estimated the total number of species
to be 121–723 and 120–713, respectively. Both the Shannon and Simpson
indexes indicated that the alpha diversity of fungal communities in the
leaves of the four regions was ranked as follows: WZS > BS
> DZ > WN.
