Abstract
In the present studies an attempt has been made to evaluate the effect of various
plant growth regulators on the yield of sennosides in C. angustifolia. The growth regulators which increased the yield of sennosides either by increasing
their percentage or by increasing the total growth of plants were N, N–Succinic acid
dimethylhydrazide (B9), (2–Chloroethyl) trimethyl ammoniumchloride (CCC), 2–Chloroethyl phosphonic acid
(Ethrel), Maleic hydrazide (MH) and 6–Furfuryl–aminopurine (Kinetin). Treatments with
Indole–3–acetic acid (IAA), Gibberellic acid (GA) and Phosfon–D were not beneficial
in increasing either sennosides content or dry matter accumulation in shoot.
