Effect of some plant extracts on seed viability and seed borne fungi of Sorghum seed during storage periods

Abstract

The present study was conducted at the Laboratory of Seed Technology Research Unit, Mansoura, Egypt to study the effect of plant extracts neem (Azadirachta indica), Moringa (Moringa oleifera ), basil (Ocimum basilicum L.) and datura (Dataram stramonium) as seed treatments on storability of of Sorghum seeds. Different concentrations (25, 50, 75 and 100%) of the different plant extracts beside distilled water and storage periods (0, 4 and 8 months) on seed quality of Sorghum cultivar Dorado were used. The obtained results showed that Moringa plant extract at 25% concentration showed the highest results of seed and seedling vigor characters and also reduced infected seed when compared with other seed treatments. Also, the results illustrated that the inhibitory effects of all plant extracts on seed borne fungi was increased as concentration of extracts increased from 0-100%. Finally, it could be concluded that moringa plant extracts at 25% concentration is a good seed treatment for enhancing germination and good control of seed borne fungi on sorghum seed.
