APRICOT MICROPROPAGATION<br />

occurs frequently <strong>and</strong> needs to be controlled by immersing the shoot tips in concentrated<br />

BA solution. High percentages <strong>of</strong> apricot in vitro plantlet acclimatization can<br />

be achieved by using st<strong>and</strong>ard procedures. Micro propagated plants, on their own<br />

roots, are an alternative to grafted plants when the chosen rootstocks are apricot<br />

seedlings. A better root system <strong>and</strong> the elimination <strong>of</strong> problems related to the grafting<br />

point are characteristics <strong>of</strong> self-rooted plants obtained by micro propagation.<br />

medium in darkness.<br />
