Root Colonization and Growth Enhancement of Micropropagated Feronia limonia (L.) Swingle by Piriformospora indica - A Cultivable Root Endophyte

摘要

In vitro-raised plantlets of Feronia limonia (L.) Swingle were colonized using an endosymbiotic root fungus Piriformospora indica during in vitro rooting and their ex vitro transfer. Improved growth has been observed in terms of higher shoot and rootlength, internode diameter, area and number of leaves and both fresh and dry weights in plants showing an association with this fungus. More than 90% of such plants survived in the greenhouse and subsequently under a nursery shed. The study demonstratedthe potential of P. indica as a biopriming agent for achieving better growth and survival of tissue culture raised plantlets.
