Dynamic analysis of Tapping Panel Dryness in Hevea brasiliensis …
ਵੈਬROS-TPD-affected trees can recover a normal latexflow after a resting period (Jacob et al., 1994). The second symptom associates both an irreversible cessation of latex flow and brown bast (BB). BB-TPD deals with a deformation of bark due to thylosoid formation, lignified gum, and abnormal division of parenchyma cells (de Faÿ and Jacob, 1989).
Overview of Brown Bast Syndrome of Hevea Brasiliensis
ਵੈਬBrown bast is one of the most serious threats to natural rubber production. In general, high-yielding clones of rubber tree are often considered to be more susceptible to this physiological disorder also commonly termed Tapping Panel Dryness (TPD). It is estimated that brown bast leads to approximately 15-20% decrease in yield.
