Other claims from this paper (13)

Intervention effect Bicarbonate decreased shoot and root dry weight in both cultivars.
Intervention effect High pH decreased shoot and root dry weight in both cultivars.
Intervention effect Bicarbonate decreased shoot and root dry weight more than high pH.
Observation Growth inhibition was less in Zn-efficient S 101 than Zn-inefficient G1?2.
Intervention effect Bicarbonate significantly decreased root length in Zn-inefficient cultivar.
Intervention effect High pH significantly decreased root length in Zn-inefficient cultivar.
Intervention effect Bicarbonate enhanced root length in Zn-efficient S101.
Intervention effect Bicarbonate enhanced root length more than high pH in Zn-efficient cultivar.
Intervention effect Bicarbonate increased root organic acids in both cultivars.
Intervention effect High pH increased root organic acids in both cultivars.
Observation Organic acid increase was greater in Zn-inefficient than efficient cultivars.
Mechanism Authors suggest impaired root growth initiates bicarbonate-induced Zn deficiency.
Mechanism Authors suggest organic-acid accumulation and compartmentation explain inhibited root growth.
