2.3. Data Analysis. The relative frequency of colonization (%
CF) of endophytes was calculated as the number of isolates
of taxon from each segment divided by the total number of
segments plated × 100 [19]. Dominant endophytes expressed
as percentage [20] were calculated as percentage colonization
frequency divided by sumof percentage colony frequencies of
all endophytes × 100. The isolation rate (IR) was calculated as
the number of isolates obtained from the segments divided
by the total number of segments plated and expressed as a
fraction [21].
