Zusammenfassung:Trees of a highland provenance of Pinus caribaea var. hondurensis Barr. and Golf, in an unhealthy stand on Melville Is., Australia displaying symptoms of needleless shoots, short needles, premature needle fall, resin exudation from the stem, fasciation of the stem tip, tip dieback and multiple leadering were markedly improved by the application of Zn. Other plantings of highland provenances of P. caribaea var. hondurensis in the lowland tropics with similar disorders may benefit from Zn application.
