Gibberellic acid and cycloheximide influenced the growth and biochemical constituents of a medicinally important plant - Trachyspermum ammi (L.) Sprague.

The effect of growth promoter gibberellic Acid (GA3) and growth inhibitor cycloheximide (CH) was tested on seedlings of a medicinally important plant -Trachyspermum ammi. The seedlings under the GA3 influence showed enhanced germination, seedling elongation and dry weight accumulation, and retarded effect on moisture absorption. The CH had inhibitory effect on percentage of germination, moisture content and seedling elongation, while dry weight accumulation was more. Both GA3 and CH showed stimulatory effect on reducing sugars with decline in total sugar levels, whereas protein content enhanced with retarding levels in total amino acids.
