Other claims from this paper (15)
- Intervention effect In Sahara 3771 under excessive B, cell width and cell numbers in the meristematic zone increased.
- Intervention effect In Clipper (B intolerant) under excessive B, the length of the root meristematic zone decreased significantly.
- Intervention effect In Clipper under excessive B, the width of the meristematic zone showed no significant effect.
- Intervention effect In Clipper under excessive B, cell numbers in the meristematic zone decreased.
- Intervention effect In Clipper under excessive B, individual cells along the meristematic zone increased in length and width.
- Intervention effect Excessive B led to significantly lower osmotic potential in the root tip cell sap of SloopVic (B tolerant).
- Intervention effect Excessive B led to significantly lower osmotic potential in the root tip cell sap of Sahara 3771.
- Intervention effect In Clipper the opposite osmotic potential response was observed under excessive B.
- Intervention effect Sugar levels in SloopVic root tips were enhanced between 48 and 96 h after excess B was applied.
- Intervention effect The root elongation rate of SloopVic increased under excess B.
- Intervention effect Sucrose level in mature leaf tissue of SloopVic showed a 2.7-fold increase under excess B.
- Intervention effect Reducing sugar levels in Clipper root tips decreased significantly under excessive B.
- Intervention effect Root elongation rates of Clipper were significantly lower under excessive B.
- Intervention effect Sucrose levels in leaf tissues of Clipper were lower under excessive B.
- Mechanism The results indicate a B tolerance mechanism associated with complex control of sucrose levels between leaf and root tip that maintains root growth under B toxicity.
