Variability of cuttings and buddings in three Hevea cultivars.

摘要

The relative performance of planting materials derived from conventional cuttings and buddings of 3 genotypes (cones PB 85, GT Q and FX 652) in an existing experiment was compared. Results of the study indicated that (1) there was no significant superiority of cuttings over buddings with reference to yield and girth; (2) cuttings were not necessarily more uniform than buddings and (3) both cuttings and buddings exhibited a common characteristic of a decline in yield as tapping approached the ground. As the cuttings studied were obtained using conventional methods which gave rise to adventitious root systems the information obtained may not be applicable to those obtained from micro-cuttings, seedling cuttings and other tissue culture plants with their own 'tap-root' systems.
