Micropropagation of Pistachio from mature trees

Multiple shoots were induced from nodal segments of mature trees of Pistacia vera L. on Murashige and Skoog (MS) medium supplemented with benzylaminopurine (BA). Maximum shoot production was obtained from shoot tips taken from in vitro proliferated shoots when cultured on solidified MS medium containing 8.8 mu M BA. The multiplication rate was 20 microshoots per explant on the 30th day. Rooting of microshoots was achieved in MS medium supplemented with indole butyric acid (IBA). Rooted plantlets reassumed independent growth after a short period of acclimatisation. Stable regenerated plants were established in the greenhouse.
