Abstract

The relation between ortets and ramets with the characteristic number of latex vessel ringswas studied at 30 cm, 60 cm and 90 cm height on stem of rubber tr~e. The objective was to identify the maintenance of this character in the ramets. It was also studied the performance of 100 ramets during two years. The bark thickness and the number of vessel rings were little influenced by the environmental conditions during the two years. The evaluation of the number of rings at 60 cm height in the stem demonstrated to be more appropriate for selecting productive ortets. The utilization of a index taking into consideration thesum ofthe ring number inthe measured heights and the standard deviation was more appropriated to identify the ramets that preserve ali the characteristics of the ortets.
