Abstract

Hevea latex is a hydrosol in which rubber occurs in the form of discrete particles in a diameter range of 50 A - 3 u. The particle size distribution in forty clones was investigated and their various diameters were determined by a standardised electron microscopic method. Number average diameter varies from 942 1858 A and this can be influenced by changes in the exploitation system such as the stimulation practice. It is shown that electron microscopy is a reliable method for particle size studies on latices if modern methods are used. A computerised measurement system will no doubt speed up the tedious manual procedures used in this paper.
