Abstract

Abstract: Acacia dealbata is a famous kind of economical and oremental trees in Australia. In this test , shoot tips taken from big trees and seedlings , little leaves from young plants , epicotyls from seeds were collected as explants that were studied on tissue culture and rapid propagation. The results
showed that all four kinds of explants have been induced callus formation. Buds and shoots can be induced on callus except little leaf’s callus in morphogensis. The medium MS + 6-BA 6 mg/ L + NAA 0. 1 mg/ L + NaH₂PO₄30 mg/ L may increase sprouting bud rate from callus. However , the medium
MS + 6-BA 2 mg/ L + NAA 0. 1 mg/ L + NaH₂PO₄ 30 mg/ L may increase shoot growing rate. Plantlets from test tubes grew better on the growth medium perlite + peat (1∶1) than on other components in acclimatization stage.

Key words: Acacia dealbata, Tissue culture, Rapid propagation, Acclimatization
