Abstract:
Various parameters of auxin transport in Zea mays coleoptiles as influenced by change in temperature from 5°C to 30°C was followed. The absorption of 14C-IAA from apically applied donor blocks by the tissues is a linear function of time and progressively increases with temperature up to 25°C. On the basis of the diffusion constant of 7 in agar for auxin at 20°C it was determined that the major fraction of uptake of 14C-IAA derives from an active absorption. Both the transport intensity and the velocity were found to be temperature dependent upto 25° C.
