Abstract EN
Aluminum (Al) sensitive wheat cultivar kalyansona was grown for 14 d in a range of Ca solution (125, 625, and 2500 μM) plus other nutrients without Al.
At 14 d after Ca treatment, half of these plants were harvested (H1), and the rest of the plants were exposed to 100 μM Al for additional 6 d and harvested (H2).
Severe Al injury was found only in the plants with the lowest supply of Ca before Al treatment.
Aluminum concentration in the apoplastic fluid was very high at 125 μM Ca probably because the plasma membrane of some of the cells was destroyed due to the attack of 100 μM Al.
Aluminum content in roots decreased with increasing supply of Ca before Al treatment.
Calcium content decreased drastically at harvest (H2) in the plants with 100 μM Al.
Under Al stress conditions, the plant responded to Al in different ways due to not only the different Ca supply but also the variation of Ca content in the plant tissues.
Actually, the plants having the largest Ca content in the roots before Al treatment can receive less Al injury during Al treatment.
To substantiate this idea, a companion study was conducted to investigate the effects of 2500 μM Ca supply during, before, and after 100 μM Al treatment on root growth.
The results indicated clearly that exogenous Ca supply before Al treatment is able to alleviate Al injury but less effective than Ca supply during Al treatment.
