Callus was induced from the fruit galls of Actinidia polygama on the B
5 medium supplemented with NAA, BA and kinetin (1 mg l(-1) each). When
the callus was subcultured on the same medium 3 times, shoot primordi
a and adventitious roots appeared on the surface of the callus. Shoots
subcultured on growth regulator free MS medium or supplemented with N
AA (1 mg l(-1)) formed roots. Chromosome numbers in the root tip of re
generated plantlets were determined as 2n=58, which was the same as th
at of the mother plants.
