Abstract

Summary Drought-resistant provenances of Casuarina cunninghamiana Mig, Casuarina glauca Sieb. ex Spreng. and Allocasuarina verticillata L. Johnson were established in 1984 on two sites, one (Duda'im) with low, mean annual rainfall of 204 mm, and the other (Tiberias) with infertile soil and mean annual rainfall of 431 mm. The seedlings of nearly all provenances were taller and had a larger DBH at Tiberias than at Duda'im, with a highly significant main effect of “site”. The analysis indicated that in the semi-arid environment of Israel, water, rather than soil, was the limiting factor for casuarina growth.
