Fresh biomass (A, B, C) of lettuce (L. sativa)
and protein content (D, E, F) in lettuce (Lactuca sativa) exposed to NPATZ and ATZ with concentrations ranging from low,
medium, to high and different exposure durations (short-, medium-
and long-term). Data are mean ± SE (n = 3).
The different letters indicate statistically significant differences
between treatments within the same exposure duration by one-way ANOVA
and Duncan’s honestly significant difference tests at α
< 0.05 (capital letters for shoot tissues and lower-caseletters
for root tissues). CK: control check, control plants without exposure
to chemicals. NPC: exposure to a polymeric carrier without the ATZ
(control). NPATZ-L: exposure to a low concentration of NPATZ. NPATZ-M:
exposure to a medium concentration of NPATZ. NPATZ-H: exposure to
a high concentration of NPATZ. ATZ-L: exposure to a low concentration
of ATZ. ATZ-M: exposure to a medium concentration of ATZ. ATZ-H: exposure
to a high concentration of ATZ.
