The effect of gibberellic acid alone and when combined with [2-chloroethyl]-trimethyl ammonium chloride on the growth and alkaloid content of Solanum laciniatum aiton.
Solanum laciniatum Aiton treated with Gibberellic acid (GA3), [2-chloroethyl]-trimethyl ammonium chloride (CCC), and their combinations at early and late stages of growth showed that early application of 2000 ppm CCC produced the greatest stem, leaves, and whole plant dry weight, followed by the combination of early application of 1000 ppm CCC and late application of 100 ppm GA3; whereas all GA3 treatments decreased the dry weight production compared with the controls. Regarding the glyco-alkaloids, the highest percentage was obtained from the whole plant by early applications of both strengths of GA3 compared with other treatments or the controls. On the other hand, early application of 1000 ppm CCC and also late application of 50 ppm GA3 when combined with early application of either 1000 ppm or 2000 ppm CCC produced greater alkaloid percentage yields in stem, leaves, and whole plants more than other treatments or the controls. However, early application of 2000 ppm CCC produced the highest content of alkaloids in leaves and whole plants; this was followed by yields from early application of 2000 ppm CCC and 50 ppm GA3; yields from early application of 100 ppm GA3 and 1000 ppm CCC; and yields from early application of 1000 ppm CCC +50 ppm GA3.
