Abstract Tomato pollen grains germinate readily in a solution containing only sugar and boric acid, although subsequent growth is at a rate much lower than that in the style. These experiments were designed to test the hypothesis that the action of boron is to prevent the toxic effects of high auxin levels, and to investigate the role of auxin in germination and pollen-tube growth.No evidence could be found for an interaction between indol-3yl-acetic acid and boron of the kind required by the hypothesis. Several inhibitors of growth and metabolism (maleic hydrazide, trans-cinnamic acid, iodoacetate and abscisic acid), and indol-3yl-acetic acid at high concentrations and ethylene inhibited germination to varying extents, but promoted tube elongation. It is suggested that there are two distinct phases in the early growth of the pollen grain-germination and elongation-and that they differ in their sensitivity to chemical treatment. An active endogenous inhibitory system appears to be established soon after germination, which controls the rate of growth of the pollen tube. This inhibitory system can be inactivated by treatments which cause the production of ethylene.
