Abstract
The gum-inducing chemical and Ethephon (2-Chloroethyl phosphonic acid) 100-ppm solution were
injected, 5 ml each, in the stem of Acacia Senegal plants. With the help of manually operated drill, 5 mm
diameter and approximately 4-5 cm deep transverse hole was made. Treatments were given by using syringe
and hole was sealed immediately after the injection. Gum tears appeared (may be eccrine, granulocrine and
holocrine) after couple of weeks. The maximum number of gum tears per plant (9.66) was observed in the plants
treated with the gum-inducing chemical. The plants given Ethephon 100 ppm treatment (8.66) followed this. In
control, the least number of gum tears i.e. 1 (one) was observed. The maximum production (142.33 g/plant) was
recorded in the plants treated with the gum inducing chemical, while the plants given Ethephon 100 ppm
treatment stood second (124.00 g/plant). Control could produce the least (41.33 g/plant) gum. Gum inducing
chemical and Ethephon 100 ppm gave 244.37% and 200.37 % more gum production over control, respectively.
