文摘
- •
L. sativa would be more suitable than B. oleracea for growing in soils with low Zn availability.
- •
NO3− reduction and NH4+ assimilation are reduced and photorespiration is enhanced by Zn deficiency in both species studied.
- •
Zn deficiency changed the free AAs profile in both species studied.
- •
Gly accumulation could help L. sativa plants to accumulate more Zn in deficiency conditions.
- •
B. oleracea is able to accumulate N derived protective compounds to cope with Zn deficiency stress.
