Seed germination improvement in three important medicinal plant species Abelmoschus moschatus (Medik), Asparagus racemosus (Willd), and Cassia angustifolia (Linn)
RKS Tiwari and Satish Dubey
In the present study, dormancy and germination requirement were investigated in one year old and fresh seeds of three important medicinal plants are Asparagus racemosus, Cassia angustifolia, Abelmoschus moschatus seeds were subjected to 12 pretreatments in the present study. There was Significant result on fresh seeds of Abelmoschus moschatus both under in vitro and in vivo conditions. Seed germination recorded from one year old seed treated with most of the treatments was at par with untreated control. However, water soaking for 24 hrs, Gibbrellic acid and sand paper scarification had higher per cent seed germination on fresh seed under in vitro and on both fresh as well as one year old seeds under in vivo conditions. In vivo, maximum percent of 86.50 was recorded from fresh seed soaked only in water for 24 hrs whereas, in control, percent seed germination was 30.0.Most of the treatments did not have any effect on seed germination on fresh and one year old seed of Asparagus racemosus under in vitro and in vivo conditions. However, Hot water treatment (70 0C) for 1hr had significant positive effect on one year old seed germination (47.00) closely followed by Cow dung Water + 24 hrs water Soaking (76.00). Moreover, cow dung water + 24 hrs Gibbrellic acid solution and cow dung + water Soaking for 24 hrs did also have significant positive effect. Cassia angustifolia, sand paper scarification + 24 hrs water soaking showed promising results significantly enhancing seed germination of on fresh seed (64.00) under in vitro condition and on one year old seed (57.00) under in vivo conditions. Whereas in control, seed germination of 34.67 and 23.50 per cent respectively recorded from fresh and one year old seeds.
