EXPERIMENTATION ON THE PROPAGATION OF BACCHARIS TRIMERA (Less.) DC, COMPOSITAE (CARQUEJA)

Plants were propagated by fruits and cuttings.
Cuttings were rooted in two seasons: autumn (May 19, 1992), in a field nursery under plastic cover, and spring (September 14, 1992) in plastic containers under shade.
Seeds were sown in a field nursery under plastic cover on June 8, 1992. Plants were taken to the field on November 25, 1992, planted at a spacing of 30 x 40 cm.
For the three treatments, the mortality of plants after transplanting was 42, 4 and 46% respectively.
Within each treatment, plants were harvested on February 5, 1993, November 12, 1993 and November 3, 1994. Dry matter yield was measured for plants propagated by cuttings in autumn, for plants propagated by cuttings in spring and for plants propagated by seed.
The results were 154 g/plant, 235 g/plant and 215 g/plant respectively.
If compared to plants obtained by the same methods, but which were only harvested on one occasion (December 23, 1993), dry matter yields were respectively 174, 199 and 251 g/plant.
These results were not subject to statistical analysis.
