ABSTRACT :
[TEXT IN BAHASA MALAYSIA] A method of estimating the osmotic sensitivity of latex bottom fraction was developed using the extent of particle aggregation as an index of damage and the osmotic sensitivity of bottom fraction related to changes in latex osmotic concentration during flow. Information has also been obtained on (i) clonal differences in osmotic sensitivity of bottom particles (ii) and on the effect of calcium ions on the stability of particles. These studies suggest that osmotic damage to the bottom fraction is accentuated by calcium ions present in the bark tissues and that the subsequent flocculation of latex resulting in the closure of latex vessel may largely occur on or near the cut ends of the surface of the tapping cut.
