3). In both
culture systems, Fe and Zn + Mn priming resulted in an approximately
100% increase in total root length after 3–4 weeks exposure
to low RZT (Table 4). Root length in different diameter classes (0.2,
0.4 and 0.6 mm) revealed that nutrient seed priming particularly promoted the growth of fine roots, as compared to unprimed and
water primed treatments at low RZT
