Abstract
Intact barley coleoptiles subjected to high temperature stress of 46°C for up to 4 h showed a significant decrease in their growth rate, and in the final length attained by the coleoptiles before exsertion of the true leaves within. These effects of high temperature were progressively more pronounced with increase in duration of stress. Excised wheat coleoptile sections also experienced a similar growth retardation due to heat stress. This heat-induced growth retardation could not be prevented by exogenous applications of 0·5–100 ppm indole-3-acetic acid or 0·5–5 ppm gibberellic acid; nor by dilute aqueous solutions of calcium chloride, cobalt nitrate or zinc sulphate. The agronomic significance of heat-induced coleoptile stunting is briefly discussed.
