The Rooting of Cuttings of Metasequoia


Summary


The plant material included in this experiment was collected during the winter
and the summer of 1983. The cuttings of Metasequoia glyptostroboides Hu et Cheng
were taken from two trees of different age (10 and 25 years), in order to study the
possibility of mass production vegetative copy.


An experiment of rooting winter cuttings (15 March 1983) and summer cuttings
.´22 August 1983) was made under greenhouse conditions. In both tests the cuttings
were placed in the rooting medium consisting of 75% of coarse sand and 25´% peat.


Regarded in whole, the results of rooting summer cuttings show that the success
of rooting was 25%. But from cutings from younger tree one has obtained 34%, of
tooted cutings which is for 11,50% more than of cuttings from older tree (Table 2).


Rooting of winter cutings in whole (45,20%) is more successful than rooting
of summer cuttings (25%). However, from cutings from younger tree one has obtained
55,67% of rooted cutings which is for 29,50% more than of cutings from older
tree (Table 1).
