A METHOD FOR THE IN SITU ACTIVATION OF THENEEDLE FASCICLES OF GYMNOSPERMS ANDFOR THE CLONAL PROPAGATION OFGYMNOSPERMS AND THE CLONES PRODUCED THEREBYABSTRACTA method for the in situ activation of thenormally dormant needle fascicles of gymnosperms and theclonal propagation of gymnosperms and the clones producedthereby. The method for the in situ activation of theneedle fascicles of gymnosperms to produce shoots com-prising the step of contacting the terminal portion of astem of the gymnosperm with between about 0.01 to 20 mgof a cytokinin. And, the method for the clonal propaga-tion of gymnosperms and the production of clones thereofcomprising the steps of contacting the terminal portionof a stem of the gymnosperm with between about 0.01 to20 mg of a cytokinin; allowing the shoots to elongate;excising the elongated shoots from the stem and rootingthe excised shoots.
