abstract：:The expansion growth of plant organs is inhibited at low water potentials (Ψ w), but the inhibition has not been compared in different organs of the same plant. Therefore, we determined elongation rates of the roots, stems, leaves, and styles (silks) of maize (Zea mays L.) as soil water was depleted. The Ψ w was measu...

When the concentration of UdR is progressively increased, an inversion of the effects of UdR is observed; this inversion may go as far as complete reversal of the inhibition caused by 5-BUdR in the case of hypocotyl growth. 2....
