How to germinate Asparagus racemosus

Asparagus racemosus (Shatavari) is a perennial medicinal plant native to tropical and subtropical regions of Asia and Africa. It has been used in Ayurvedic medicine for over 3000 years. Seeds suffer from physiological dormancy requiring pre-treatment for optimal germination.

Before sowing

Scarification

quimica 20% sulfuric acid solution increases germination to 84-86%; hot water at 50°C also effective

Soak

24 h Soak seeds in warm water (120°F) or at room temperature for 12-24 hours before sowing; water soaking alone at 24 hours achieves 86.50% germination in vivo

Seeds exhibit physiological dormancy; chemical (sulfuric acid 20%) or hot water (50°C for 1 hour) treatments effective; gibberellic acid also stimulates but less effective than acid

Sowing

Tips

Fresh seeds not required; excellent results with 4-year-old seeds reported. Germination can be highly variable, ranging 17-60% without treatment but up to 86% with proper pre-treatment. Maintain warm, moist conditions throughout germination. Seedlings transplanted to individual pots when large enough to handle. Plant difficult from seed; considered dioecious in some forms requiring male and female plants for seed production.
