| Abstract: | The quality of shoots in cultures of the apple rootstock, M4, was used as a criterion for the selection of an optimum medium.
The frequency of shoots in defined shoot clases was monitored for each of five media, which differed in the type and concentration
of phytohormone. Media containing BA (1.15 mg l-1) and IBA (either 0.15 or 0.20 mg l-1) produced the maximum number of shoots that were desirable for transplantation and acclimatization. |
