Technical Annual Report 2000/01 121 SUBPROGRAM: Bamboo PROJECT: Bamboo Project Officer: M. Traynor Location: CPHRF Objective: In the wake of poor preformance by B. oldhamii, to try other bamboo species suitable for local conditions. Due to the poor performance of B.oldhamii, project participants decided to terminate research on that species and concentrate on the species preferred by researchers and local growers. The trial of B.oldhamii was discontinued in May 1999 and replaced with D.latiflorus and D.asper in November 1999. D. Latiflorus Preliminary Observations: Shoot size in clumping bamboos is strongly affected by the number of culms or stems per clump. Fewer culms for the rhizome to support means larger shoots will be produced. The effect of total culm number and their age on shoot and culm diameter is a component of future research. The seven plants of D.latiflorus in the variety collection at CPHRF have been harvested during the last three Wet seasons. These clumps have been managed with a total of 18 culms per clump. This means that after each yearly thinning, three generations of culms remain (six each of one, two and three year old). The shoot yield data for these clumps is presented in table 1. Shoots were graded by base diameter of cut and trimmed shoots. Table 1. D. Latiflorus shoot yield (kg) average of seven clumps 90 mm 100 mm 110 mm 120 mm 130 mmHarvest season No. Wt. No. Wt. No. Wt.

From Table 1, several points regarding the performance of D.latiflorus are worth noting: At 200 clumps/ha yields range from 5.0 to 7.5 tonnes/ha. Average shoot weight over three harvests remains constant. Shoot number seems variable and could be a result of the intensity and duration of Wet season rainfall. There appears to be a high percentage of shoots of less than 1.0 kg. The culm density of 18 may be restricting potential shoot size. The sample of D.latiflorus clumps is too small to draw firm conclusions from this data.
