Seed biology of Andrographis elongata T. And. (Acanthaceae) – a valuable endemic medicinal plant of India
Abstract
The present investigation deals with the seed biology of an endemic medicinal plant species, Andrographis elongata T. And. of Acanthace family. Its leaves, whole plant, root flowers and seed are used as medicine. Its major bitter principles are 2¢-oxygenated flavones. It is useful in the treatment of snake bite, diabetes, antidiabetic malarial fever, diuretic, skin disease and constipation. Due to its powerful medicinal importance, the plant is over exploited from the natural habitat and it is very endemic and necessity high conservation utility. The species is under severe threat due to various reasons including reproductive inability. The present research pointed to analyze the seed biological status and germination evaluate in the natural as well as in the laboratory condition. The new seeds showed 72 viability and 42% germinability. But the seeds employed with Gibberellic acid (GA3) (100, 200, 300, 400, 500 ppm) showed 60 to 78% germinability and 84 percentage of the seed germination noted after 90 days. The highest seed germination was observed in GA3 300 ppm (84%).
