Studies on Effects of Arbuscular Mycorrhizal (Am.) Fungi on Mineral Nutrition of Carica papaya L.
Keywords:Carica papaya L., Glomus intraradices (Schenck & Smith), Glomus mosseae [(Nicol. & gerd.) gerd. & Trappe], leaf petiole, total phosphorus, total potassium
Experiment was conducted to study the effects of arbuscular mycorrhizal fungi on mineral nutrition of Carica papaya var. Surya. The experiment comprised of un-inoculated seedlings, seedlings inoculated with Glomus intraradices Schenck & Smith, seedlings inoculated with Glomus mosseae [(Nicol. & Gerd.) Gerd. & Trappe] and seedlings inoculated with mixed inoculum [Glomus intraradices (Schenck & Smith) + Glomus mosseae (Nicol. & Gerd.) Gerd. & Trappe]. Studies revealed that total potassium and total phosphorus content of mycorrhizal leaf petiole was higher in inoculated plants as compared to controls and varied significantly within the treatments. Glomus mosseae was the most effective species of AM fungi, in influencing mineral nutrition of papaya followed by mixed inoculum (GI +GM) and Glomus intraradices respectively.
