Zhao X. Q., . The significance of the structure of laticifer with relation to the exudation of latex in Hevea brasiliensis. pp. 94-98. ISSN 0127-7065
Abstract
Many investigations on the structure of the laticifer in Hevea brasiliensis had been carried out about a century ago. The methods used in previous studies were by tissue sectioning. However the present study is based on a new technique of isolating the complete network structure of the laticifer from the bark of the tree without sectioning. The procedures of the technique consist of mainly removing the bark from the tree softening in boiling 10 KOH for about 15-20 min dehydrating up to 80 alcohol and staining in Sudan III or Sudan IV dissolved in 75 alcohol. The stained tissue will show red indicating that it is ready for examination under the microscope and for taking photographs. Through this method of study it has been revealed that there are two kinds of laticiferous tissues in the same plant. They are the non-articulated laticifer and the articulated laticifer. These tissues differ very much from each other by their origin structure ontogenetic development and distribution in the bark of the plant. The accompanying coloured photographs demonstrate the way of transportation and exudation of latex in the network structure of the laticifer.
