Description
Summary:Commercially important ornamental flowering plant Crossandra infundibuliformis (L.) Nees. commonly known as 'Fire cracker' plant was evaluated for the possible effects of inoculation of different Arbuscular Mycorrhizal (AM) fungal species on growth, yield, flower quality, and phosphorus (P) nutrition. Five pure cultures of AM species, Acaulospora laevis, A. scrobiculata, Glomus coremioides, G. intraradices and Gigaspora albida and an un-inoculated control were used. Mycorrhizal inoculation showed positive effect on plant height, early flowering, increased flower number, increased flower weight, reduced fresh weight loss over 24 h, increased leaf P concentration, and increased total dry weight compared to un-inoculated control. The studies indicate mycorrhizal inoculation can enhance commercial flower production of this plant. Glomus intraradices proved to be the most efficient AM fungal bioinoculant and thus have the potential to enhance commercial flower production of this plant.
