<p>La simbiosis entre plantas de cacao y hongos micorrízicos arbusculares (HFMA) confiere beneficios nutricionales y competitivos a la planta, especialmente en condiciones de baja disponibilidad de nutrientes. Se evaluó tres niveles de fósforo (5, 20 y 40 ppm) y la presencia o ausencia de isoflavonoide formononetina. El nivel 14 ppm de P sin el isoflavonoide fue el tratamiento testigo. Todos los tratamientos fueron inoculados con HFMA a excepción del tratamiento control. Se utilizó un diseño completamente al azar y se determinaron caracteres morfológicos de la planta a los 70, 110 y 150 días después de la inoculación. Los resultados no mostraron respuesta diferencial a los caracteres morfológicos de la planta por la disponibilidad del isoflavonoide durante los tres muestreos. La longitud radicular presentó diferencias significativas en los muestreo (70, 110 y 150 días de inoculación), siendo esta respuesta dependiente de la disponibilidad de P y la interacción plantamicorriza. El número de esporas mostró diferencias entre los muestreos de 110 y 150 días de inoculación en presencia y ausencia del isoflavonoide, sugiriendo una rápida estimulación en el establecimiento de la relación simbiótica por la formononetina en el proceso de germinación y formación de estructuras fúngicas.</p><p> </p><p><strong>Symbiotic asociation of arbuscular mycorrhizal fungi and the root system of cocoa (Theobroma cacao L.) seedlings: effect of formononetin and phosphorus availability at soil level</strong>.</p><p>The symbiosis established between cacao plants and arbuscular mycorrhizal fungi (AMF) adds nutritional and competitive benefits for the plant, especially in conditions with a low availability of nutrients. We evaluated three levels of phosphorus (5, 20 and 40 ppm) and the presence or absence of isoflavone formononetin. A Phosphorus level of 14 ppm, without isoflavone or inoculation was the control. All treatments were inoculated with HFMA with the exception of the control. A completely randomized design was used. The morphological characters of the plant at 70, 110 and 150 days after inoculation were determined. The results showed no difference in the response to the morphological characters of the plant with the varied availability of isoflavone during the three sampling. The root length showed significant differences in the different sampling times (70, 110 and 150 days of inoculation), this response being dependent on the availability of P and plant-mycorrhizal interactions. The number of spores demonstrated differences between the samples of 110 and 150 days of inoculation in the presence and absence of isoflavone, suggesting an early stimulation in the establishment of the symbiotic relationship of formononetin in the process of germination and formation of fungal structures. </p>

Sugar palm is one of local plants spesies that may potential for reclamation program because can be planted under the stands of forest crops. Forest crops can be shade seedlings sugar palm from direct sunlight because the growth of sugar palm is relatively slow. Sugar palm can be useful even without cutting down the trees. Previously, sugar palm had been planted at PT Berau Coal and had produced fruit. The research was conducted at coal post-mining land of PT Bukit Asam, Tanjung Enim, South Sumatera. The research using combination of AMF and liming treatment is as follows, ie MaK0 (control), Mak1 (seedling with AMF without inoculation; liming 30 g plant-1), MiK0 (AMF indigenous seedling inoculation; without liming), MiK2 (AMF indigenous seedling inoculation, liming 60 g plant-1), MmK0 (AMF mycofer seedling inoculation; without liming), and MmK3 (AMF mycofer seedling inoculation, liming 120 g plant-1). The results showed that sugar palm could be grown in the coal post-mining land. The combination of AMF and liming treatment did not significant effect on observed variables of plant height, rachis length, diameter, leaves number, number of spore and root cholonization. Sugar palm seedlings that have been infected with AMF could be grown and provide a good growth response even without liming.Keywords : Arbuscular Mycorrhizal Fungi (AMF), marginal land, sugar palm

AbstractDeficit irrigation (DI) improves water use efficiency (WUE), but the reduced water input often limits plant growth and nutrient uptake. The current study examined whether arbuscular mycorrhizal fungi (AMF) could alleviate abiotic stress caused by low phosphorus (P) fertilization and DI.A greenhouse experiment was conducted with potato grown with (P1) or without (P0) P fertilization, with AMF (M1+:Rhizophagus irregularisor M2+:Glomus proliferum) or AMF-free control (M−) and subjected to full irrigation (FI), DI or partial root-zone drying (PRD).Inoculation of M1+ and M2+ maintained or improved plant growth and P/nitrogen (N) uptake when subjected to DI/PRD and P0. However, the positive responses to AMF varied with P level and irrigation regime. Functional differences were found in ability of AMF species alleviating plant stress. The largest positive plant biomass response to M1+ and M2+ was found under FI, both at P1 and P0 (25% increase), while plant biomass response to M1+ and M2+ under DI/PRD (14% increase) was significantly smaller. The large growth response to AMF inoculation, particularly under FI, may relate to greater photosynthetic capacity and leaf area, probably caused by stimulation of plant P/N uptake and carbon partitioning toward roots and tubers. However, plant growth response to AMF was not related to the percentage of AMF root colonization. Arbuscular mycorrhizal fungi can maintain and improve P/N uptake, WUE and growth of plants both at high/low P levels and under FI/DI. If this is also the case under field conditions, it should be implemented for sustainable potato production.
