Summary Growth of the petioles of etiolated pea seedlings is enhanced by very low doses of red or by a broad range of far-red energies. However, red energies which establish the photostationary steady state fail to enhance this growth or can even inhibit it. This inhibitory effect can be reversed by far-red (Fig. 2). This result is explained by the assumption that the optimum concentration of P730 for growth is very low. This optimum concentration depends on how often the induction is repeated. In contrast, all other photoresponses in peas show the well-known dose-response relationship, as can be demonstrated, e.g., for the growth of internodes (Fig. 1).
