Abstract

Timur (Zanthoxylum armatum DC.) also known as toothache tree or winged prickly ash is an important large thorny wild shrub of Rutaceae family. Owing to its high medicinal properties, the plant population is rapidly depleting due to the unsustainable premature harvesting from open-access forests. Because of which the plant species can become endangered or rare in the absence of conservation measures through its mass propagation. Seed propagation in Timur is a time consuming and tedious process due to the requirement for stratification. Here, we report the effect of different seed pre-treatments including water soaking, potassium nitrate (300 mM), sodium chloride (75 mM) and concentrated sulfuric acid treatments followed by water soaking on seed germination in Timur. Seed pre-treatment with acid for 120 min resulted in rapid and synchronous seed germination whereas the control, water-soaked, potassium nitrate or sodium chloride-treated seeds failed to germinate during the observation period of 30 days. The plantlets from acid-treated seeds further established successfully. Thus, the results of the present study may be applicable in large-scale simple and low-cost mass propagation of the plant as a source of medicines and other purposes.
