Enhancement of Seed Germination and Seedling Growth of Allium victorialis var. platyphyllum by the Soaking Treatment of Plant Growth Regulators

Abstract

The effects of seed soaking treatment with the solutions of plant growth regulators IAA, GA3and BAP on seed germination and shoot and bulb growth of Allium victorialis var. platyphyllum(Korean wild garlic) were determined. A significant variation in the seed germination rate wasrecorded at all treatments for various soaking periods. Maximum seed germination was obtainedwhen seeds were soaked in IAA or GA3 solution at 200 mg L-1. The MAP treated seeds startedto germinate after 3 months. Among treatments, IAA was found to be most effective inimproving seed germination, but further seedling growth was not correlated to the soaking time. Seed soaking in IAA or GA3 solution enhanced further growth of seedlings compared withwater control treatment. Shoot and bulb growth was highest in GA3 treatments.
