Biology of Hevea brasiliensis (Rubber)

H. brasiliensis is a sturdy, quick-growing, erect tree with a straight trunk and an open leafy crown. The bark is usually grey and fairly smooth. The bark of the trunk is the part from where rubber is harvested (Fig.1). In the wild, the trees may grow to over 40 m with a life span of more than 100 years. However, cultivated plants rarely grow beyond 25- 30 m in height because of the growth reduction due to harvesting of latex by tapping (Webster and Paardekooper, 1989)5_Biology_of_Hevea_brasiliensis_Rubber
