Relationship between leaf trichomes and stomatal traits and
their adaptive variation in the common garden
The leaf trichome density was positively correlated with LMA and SD, but
negatively with SS (Fig. 4) in situ. When different populations were
grown in the common garden, leaf trichome density was significantly
lower compared with in situ (Fig. 5). The trichome density in the common
garden was positively associated only with SD (Fig. 6), while it had no
relation with other leaf functional traits. Furthermore, no correlations
between the trichome density and environmental factors at the original
sites were observed.
