Present study was carried out to standardize the dose of ethephon (2-
chloroethylphosphonic acid), a gum inducer hormone and suitable month
for its application to optimize gum yield from Anogeissus pendula without
deteriorating tree health. Separate A. pendula trees were used to inject
with three different doses of ethephon viz., 390 mg/4ml (10%), 780 mg/4 ml
(20%) and 1170 mg/4 ml (30%) active ingredients at monthly intervals
during a complete year (March, 2010 to February, 2011). Increase in mean
gum yield with the increase in ethephon dose was recorded. Maximum
mean gum yield was recorded in March, 2010 (57.18g/tree) and minimum in
August, 2010 (0.17g/tree). The cumulative gum yield was recorded
maximum during summer (1028.90g), followed by winter (965.00g) and
rainy season (862.00g). Applications of ethephon had no effect on tree
health; however, its use significantly increased sugar content of the wood
after one month of the application. Higher dose of ethephon produced
higher sugar content in the wood of A. pendula. Thus, the results of
present study suggested that higher gum yield can be obtained from
higher dose of ethephon during summer season, without affecting the tree
health.
