“…The importance of mycorrhiza association in both agricultural and ecological systems had earlier been widely recognised [17] , [15] . The increased plant growth by VAM association is usually due to increased mineral elements uptake by the hyphae from the soil [18] , Olawuyi et al, 2012), improved water relations and pest resistance of host plants [19] , [20] , plants tolerance to a variety of abiotic stresses [21] , increased resistance to soil pathogens [22] , [23] , [24] , 2013). Mycorrhizae can also resist drought in many plants under stress conditions therefore the plants infected with VA mycorrhizae are less likely to wilt under drought affected conditions [25] , [26] , [27] .…”

“…La simbiosis micorrízica arbuscular es una de las estrategias más comunes que las plantas utilizan para incrementar la absorción de nutrientes (Montero et al, 2010), esta asociación simbiótica contribuye a la absorción de fósforo (P) y nitrógeno (N) (Smith y Smith, 2011) y puede aumentar la cantidad de agua disponible para la planta en regiones áridas y semiáridas (Baum et al, 2015). Los hongos micorrízicos son capaces de activar mecanismos de defensa frente a patógenos en plantas hospederas (Olawuyi et al, 2014) e inducir cambios en la f isiología vegetal (Armada et al, 2015). Diversos estudios han mostrado la ef iciencia de los hongos micorrízicos en la promoción del crecimiento de plantas como Agave angustifolia Haw.…”

Los hongos micorrízicos arbusculares pueden contribuir signif icativamente en la nutrición vegetal, en especial en la asimilación de fósforo (P). Los agaves silvestres son sobreexplotados debido a la producción intensiva de mezcal, ocasionando la disminución de sus poblaciones naturales. Se evaluó el efecto de la inoculación con hongos micorrízicos arbusculares comerciales y la aplicación de diferentes dosis de P sobre el crecimiento y contenido de sólidos solubles totales (SST) de dos agaves silvestres: agave tobalá (Agave potatorum Zucc) y agave coyote (Agave spp.) en condiciones protegidas. Los productos micorrízicos comerciales utilizados fueron Glomus cubense (M1) y Glumix (M2) y cuatro dosis de P: 0, 14.4, 29 y 43.5 mg kg-1. El ensayo se estableció en un experimento bifactorial 3 × 4 en un diseño completamente al azar. Las variables respuesta fueron altura de planta (AP), número de hojas (NH), diámetro de tallo (DT), volumen radicular (VR), densidad de raíces (DR), peso fresco de hoja (PFH), peso fresco de tallo (PFT), peso fresco de raíz (PFR) y SST. Con referencia al control, M2 incrementó 18.2% el NH, 53.5% el PFH, 38.1% el PFT y 36% el DT en agave tobalá; mientras en agave coyote, la AP aumentó 12% y el SST 21.3%. En agave tobalá la dosis de 43.5 mg kg-1 de P mejoró 13.2% la AP, 34.9% el PFH, 36.1% el PFT, 21.5% el DT y 20.4% el VR. En agave coyote la dosis de 29 mg kg-1 de P aumentó 16.4% la AP, 44.4% el PFT y 18.6% el DT; el SST incrementó 40% con 43.5 mg kg-1 de P y el PFH 51% con 14.4 mg kg-1 de P. En agave tobalá, M2 + 43.5 mg kg-1 de P favoreció el PFH, PFT y DT. En agave coyote, M2 + 14.4 mg kg-1 de P, M2 + 29 mg kg-1 de P y M2 + 43.5 mg kg-1 de P promovieron la AP, DT y SST. La promoción en el crecimiento de ambos agaves se debió a la aplicación individual de micorrizas y P más que a la interacción de ambos factores.

“…Maize (Zea mays L.) is one of the easiest crops to grow with more widespread cultivation than any other grains [1, 2,3]. Maize is a breakfast meal rich in vitamins A, C and E, carbohydrates, essential minerals, protein, dietary fiber and calories which are good source of energy [4].…”

Introduction: Maize is an important cereal grown globally across wide range of altitude and latitude. Temperature is one of the factors that affect the viability of maize under storage conditions. Aim: This study, therefore, assessed the effect of different temperature storage levels on the morphological characters and molecular variability of maize genotypes. Materials and Methods: The seeds of maize genotypes: TZLCOMP4C3, EVDT-W200STRCO, POP66SR/ACR94, POOL18SR QPM, TZM 132, TZM 1291, EVDT- Y2008 STR and TZM 1326 obtained from the National Centre for Genetic Resources and Biotechnology (NACGRAB) Ibadan were stored at different temperature conditions of -80°C, -20°C, 5°C, 50°C, and 25°C for 6 hours. The stored maize was sown in perforated polythene bags containing 7 kg of soil and replicated thrice in a complete randomized design. The molecular variability was also investigated on the maize genotypes stored under the varying temperatures. The effect of storage temperature was significantly higher at 50°C for all growth characters but was not significant at -80°C. Results: The genotypic effect on the growth characters was significantly (p< 0.05) higher in TZM 132 with plant height (99.09 cm), leaf length (46.54 cm), leaf width (3.05 cm), number of leaves (6.25) and stem length (50.12 cm). The contribution of principal component axis (PCA) showed that PC 1 had the height variation with a proportion of 47.17% and eigen value of 2.83 across the growth characters. Molecular evaluation showed that EVDT-W200STRCO had the highest DNA concentration of 4885.7 ng/μl at storage temperature of 25°C, while EVDT-W200STCO at -20°C recorded the least DNA concentration of 26.60 ng/μl. The highest DNA concentration across the maize varieties were recorded at -20°C (POOL18SR QPM, TZM 132 and TZM 1326), 5°C (TZLCOMP4C3), 25°C (EVDT-W200STRCO and EVDT- Y2008 STR) and 50°C (POP66SR/ACR94 and TZM 1291). OPB 10 had the highest allelic no, gene diversity and polymorphic information content of 15, 0.97 and 97.0% respectively. The genetic distance matrix established relationship among the stored maize genotypes. Conclusion: Maize seeds can therefore be stored at temperature range of -20°C to 50°C depending on the variety, without losing its viability and molecular constituents.
