Abstract

The influence of the colonization with arbuscular mycorrhizal (AM) fungus, Glomus mosseae (Nicolson and Gerdemann), on characteristics of growth, osmotic adjustment compounds and activity of antioxidant enzymes in nodules of salt-stressed soybean (Glycine max (L.) Merr.) was studied in this experiment. The pot experiment was arranged as a factorial in randomized complete block design with four replications at greenhouse of College of Agriculture, Tehran University, Iran. Results indicated that the contents of glycine betaine and proline in nodules were higher in inoculated than in noninoculated plants. AM fungal colonization increased the activities of superoxide dismutase, catalase, and peroxidase in the nodules. The results indicate that the AM fungus is capable of alleviating the damage caused by salt stress on symbiotic nitrogen fixation of soybean plants by increasing the accumulation of compatible osmolytes and by increased antioxidant enzyme activity. Consequently, arbuscular mycorrhiza formation highly enhanced the salinity tolerance of soybean plant, which increased symbiotic nitrogen fixation and promoted plant growth. Posledično tvorba arbuskularne mikorize pri soji močno poveča toleranco na slanostni stres s povečano simbiontsko vezavo dušika, kar pospeši rast.

Application Of Organic Fertilizer Raw Materials Of Chromolaena odorata And Mycorrhizal Fungi On Local Corn Plant In Sub-Optimal Land)

“…Arbuscular mycorrhizal fungi (AMF) are root symbionts that provide plant nutrition and other benefits (Denison and Kiers, 2011) such as increasing P uptake by soybeans (Abdel-Fattah et al, 2014), increasing the activity of enzymes such as phosphatase (Mar Vazquez et al , 2000); increasing the salinity tolerance of soybean plants (Younesi et al, 2013); increasing soil aggregation (Bethlenfalvay and Schuepp, 1994;Borie et al, 2008;Leifheit et al, 2014); protect roots from pathogens (Sikes, 2010); and drought tolerant (Auge, 2004;Finlay, 2004).…”

PENGGUNAAN RHIZOBIUM DAN MIKORIZA UNTUK PERTUMBUHAN Calliandra calothyrsus UNGGUL

“…Kajian pada jenis C. calothyrsus menunjukkan bahwa, hasil kayu pada batang secara nyata dicapai tertinggi pada tanaman yang diinokulasi dengan rhizobium, sementara yang terendah dicapai oleh tanaman yang tidak diinokulasi (Purwantari & Sutedi, 2005) dan karenanya untuk tujuan kayu bakar, inokulasi dengan strain rhizobium diharapkan akan menguntungkan untuk menunjang peningkatan produktifitas. Pengikatan nitrogen pada legum seringkali mengalami keterbatasan terutama pada kondisi agak kering atau pada tanah yang kurang berkualitas karena buruknya perkembangan simbiosenya (Younesi, Moradi, & Namdari, 2013). Sementara itu, tampilan tanaman legum yang baik sering diakibatkan karena adanya pengaruh aditif atau sinergis karena adanya rhizobium dan mikoriza secara bersama-sama (Goss & de Varennes, 2002;Sanginga, Thottappilly, & Dashiell, 1999).…”
