Mycorrhizal Inoculation

Au Burkina Faso, l’élevage occupe plus de 80% des ménages ruraux et constitue le troisième produit d’exportation après l’or et le coton. De type extensif, cet élevage est basé essentiellement sur l’exploitation des ressources naturelles. Ainsi, il doit s’adapter aux grandes variations saisonnières et interannuelles des ressources en biomasse végétale et en eau. Or les aléas climatiques, l’étendue et la qualité des pâturages, de même que les contraintes rendent l’activité pastorale souvent précaire. C’est ainsi que cette étude a été initiée dans le but de contribuer à améliorer la production fourragère. Dans cette étude, Mucuna pruriens a été cultivé en serre et inoculé avec deux inocula de champignons mycorhiziens arbusculaires. Les paramètres de croissance ont été mesurés à 30 et 60 jours après semis. La biomasse aérienne, racinaire et totale a été évaluée à 60 jours après semis. Les résultats montrent une amélioration de la croissance en hauteur du mucuna de 225,76%, de la biomasse aérienne de 56,79%, la biomasse racinaire de 70% et la biomasse totale de 61,16% par rapport au témoin non inoculé. Cette étude a montré des résultats intéressants et mérite d’être approfondie par des essais in situ tout en étendant l’étude sur les inoculations rhizobiennes.Mots clés : Mucuna, inoculation mycorhizienne, champignons mycorhiziens arbusculaires.   English Title: Effect of mycorrhizal inoculation with arbuscular mycorrhizal fungi strains on Mucuna pruriens (L.) DC growth under controlled conditionIn Burkina Faso, breeding occupies more than 80% of rural households and is the third export product after gold and cotton. Extensive type, this breeding is based essentially on the exploitation of natural resources. Thus, it must adapt to large seasonal and interannual variations in plant biomass and water resources. Climatic hazards, the extent and quality of pastures, as well as constraints make pastoral activity often precarious. Therefore, this study was initiated with the aim of helping to improve forage production. In this study, Mucuna pruriens was grown in a greenhouse and inoculated with two inocula of arbuscular mycorrhizal fungi. The growth parameters were measured at 30 and 60 days after sowing. Shoot, root and total biomass was evaluated at 60 days after sowing. The results show an improvement in the height growth of mucuna by 225.76%, shoot biomass by 56.79%, root biomass by 70% and total biomass by 61.16% compared to the control. This study showed interesting results and deserves to be deepened by in situ tests while extending the study of rhizobial inoculations.

The photosynthesis effect of arbuscular mycorrhizal fungi (AMF) on mulberry was evaluated in karst rocky desertification area. Three-month-old sterile mulberry saplings were transplanted in karst rocky desertification area and were inoculated with Gigaspora rosea. Some growth parameters and photosynthesis indexes were measured to study the physiological responses after inoculating for 1 year. The results showed mulberries that were inoculated with AMF had greater height, larger stem diameter and leaf area, more leaf number per plant, more fibrous root number and biomass of shoots and roots, as well as higher chlorophyll content, net photosynthetic rate, transpiration rate, stomatal conductance compared with non-AMF plants. The research results confirmed that AMF markedly enhanced the absorptive ability of root system, promoted the vegetative growth, improved the photosynthetic capacity, and obviously increased mulberry survival rate in karst rocky desertification area. These results provided a theoretical base for the ecological restoration in karst rocky desertification area.

The aim of study was to know the effect of Arbuscular Mycorrhiza Fungi (AMF), Glomus mosseae on the growth of onion Allium cepa L. on red-yellow podzolic soils. Completely Randomized Design (CRD) factorial with 10 replicates was used in this experiment. The first factor was mycorrhizae, with two level: without inoculation as a control (M0); 10 gram inoculation = M1). The second factorwas leaf litter of gamal Gliricidia sepium L. species   wich were no litter as S0; 5 gram litter = S1; S2 was 10 gram of litter; and 20 grams of loitter in one kilogram of soil separately. Parameters used in this study were the growth of onion that has infected root in percent, and Relative Growth Rate (RGR). ANOVA was used to analyze the data, and followed with DMRT at 95% level test. The result showed that mycorrhizal inoculation increased root and shoot fresh weight, the dry weight of shoot; and the percentage of root infection on the onion. While the leaf litter of gamal increased only in leaf area. In contrast mycorrhizal inoculation and gamal leaf litter and their combination had no effect on other growth parameters. Key words: AMF, Glomus mosseae, Gliricidia sepium, Allium cepa.

Experiments were conducted to examine the growth and development of oil palm Elaeis guineensis Jacq. (Magnoliophyta: Arecaceae) seedlings subjected to shading, irrigation regimes and mycorrhizal inoculation in the dry season. Treatments were 2 x 2 x 2 factorial combination consisting of shade and no-shade (open sun), 7 and 14 day irrigation intervals and mycorrhizal inoculation or non-inoculation. Seedlings that were grown under shade and irrigated weekly produced highest number and length of fronds, and shoot, leaf and frond weights in addition to taller plants compared to open sun (unshaded) seedlings. Across irrigation treatments, unshaded seedlings had lower weights of leaf, frond and shoot biomass. The effects of shade treatments were significant on plant height and frond length from 2 to 20 weeks after planting. The seedlings irrigated fortnightly produced longer roots compared with the unshaded and weekly irrigated. Fortnight irrigation enhanced root development compared with weekly irrigation. Shading and weekly irrigation significantly enhanced soil moisture contents and seedling water use efficiency compared with the unshaded. Shaded seedlings irrigated weekly used larger amount of water compared with fortnight irrigation. Significant interactions were obtained between shade and irrigation regimes for most of the growth parameters measured. Mycorrhizal inoculation, shaded and weekly irrigated seedlings were more vigorous compared with the unshaded and non-inoculated.

Au Burkina Faso, le sésame est essentiellement une culture de rente. Sa production augmente progressivement alors que son rendement baisse d’année en année. Ceci est lié à la pauvreté du sol en éléments minéraux tels que l’azote et le phosphore assimilable entrainant une augmentation des superficies emblavées pour cette culture et une utilisation des intrants chimiques de plus en plus grande. Or les intrants chimiques ont montré leurs limites dans leur utilisation. C’est ainsi que cette étude a été initiée afin de contribuer à l’amélioration de la production agricole durable. Dans cette étude le sésame a été cultivé en serre et inoculé avec deux inocula mycorhiziens indigènes. Les paramètres de croissance ont été mesurés à 30 et 60 jours après semis. La biomasse aérienne, racinaire et totale ont été évaluées à 60 jours après semis. Les résultats montrent une amélioration de la croissance en hauteur de 431,25%, taux de croissance relative en hauteur de 145,87%, diamètre au collet de 163,92%, biomasse aérienne de 102,9%, biomasse racinaire de 126,67% et de la biomasse totale de 110,1% par l’inoculation. Cette étude a montré des résultats prometteurs et mérite d’être approfondie par des essais aux champs.

English Title: Sesame (Sesamum indicum L.) response to mycorrhizal inoculation with native arbuscular mycorrhizal fungi to Burkina Faso In Burkina Faso, sesame is essentially a cash crop. Its production is gradually increasing while its yield decreases. This is linked to the soil poverty in mineral elements such as available nitrogen and phosphorus leading to an increase in the area sown for this crop and an increasing use of chemical inputs. However, chemical inputs have shown their limits in their use. This is how this study was initiated to help improve sustainable agricultural production. In this study, sesame was grown in greenhouse and inoculated with two inocula of native arbuscular mycorrhizal fungi (M1 and M2) from Burkina Faso. The growth parameters were measured at 30 and 60 days after sowing. Shoot, root and total biomass were assessed at 60 days after sowing. The results obtained show an improvement in height growth of 431.25%, the relative growth rate in height of 145.87%, the collar diameter of 163.92%, the aboveground biomass of 102.9%, root biomass of 126.67% and total biomass of 110.1% of plants inoculated with arbuscular mycorrhizal fungi compared to the inoculated control. This study has shown promising results and deserves to be deepened by field tests to assess the effect of this inoculation on sesame yield.Keywords: Sesame, mycorrhizal inoculation, arbuscular mycorrhizal fungi, Burkina Faso.

A pot experiment investigated interactions between foliar endophytic (EP, Neotyphodium lolii) and root arbuscular mycorrhizal (AM, Glomus mosseae) fungi in Lolium perenne. The effects of three phosphorus (P) forms (KH2PO4-P, phosphate rock-P (PR) and phytate-P) on EP and AM colonisation and plant growth parameters were also assessed. AM arbuscular and vesicular structures were estimated by microscopic counting and fungal concentrations were quantified by qPCR of G. mosseae and N. lolii specific genes. Significantly more AM structures were formed in roots of EP-free compared to EP-infected plants, indicating that AM development is suppressed by the presence of foliar EPs. Total AM concentrations were also generally higher in EP-free plant roots, but not significantly. EP concentrations were significantly reduced by higher plant-available P in the growth medium, but mycorrhizal infection did not significant affect EP concentrations. Mycorrhizal inoculation increased shoot dry matter (DM) at low plant-available P in the PR treatment. Infection with the endophytic strain AR37 also significantly increased shoot DM and fungal concentrations were higher compared to CS (common or wild-type strain)- and AR1-infected plants. Insoluble phytate-P produced the same amount of biomass as soluble-P (K-Pi) did, suggesting that L. perenne has the ability to use organic P.

Electron Imaging

Secondary Electron Imaging (SEI) has become a useful mode of studying surfaces in SEM[1] and STEM[2,3] instruments. Samples have been biassed (b-SEI) to provide increased sensitivity to topographic and thin film deposits in ultra high vacuum (UHV)-SEM[1,4]; but this has not generally been done in previous STEM studies. The recently developed UHV-STEM ( codenamed MIDAS) at ASU has efficient collection of secondary electrons using a 'parallelizer' and full sample preparation system[5]. Here we report in-situ deposition and annealing studies on the Ge/Si(100) epitaxial system, and the observation of surface steps on vicinal Si(100) using b-SEI under UHV conditions in MIDAS.Epitaxial crystal growth has previously been studied using SEM and SAM based experiments [4]. The influence of surface defects such as steps on epitaxial growth requires study with high spatial resolution, which we report for the Ge/Si(100) system. Ge grows on Si(100) in the Stranski-Krastonov growth mode wherein it forms pseudomorphic layers for the first 3-4 ML (critical thickness) and beyond which it clusters into islands[6]. In the present experiment, Ge was deposited onto clean Si(100) substrates misoriented 1° and 5° toward <110>. This was done using a mini MBE Knudsen cell at base pressure ~ 5×10-11 mbar and at typical rates of 0.1ML/min (1ML =0.14nm). Depositions just above the critical thickness were done for substrates kept at room temperature, 375°C and 525°C. The R T deposits were annealed at 375°C and 525°C for various times. Detailed studies were done of the initial stages of clustering into very fine (∼1nm) Ge islands and their subsequent coarsening and facetting with longer anneals. From the particle size distributions as a function of time and temperature, useful film growth parameters have been obtained. Fig. 1 shows a b-SE image of Ge island size distribution for a R T deposit and anneal at 525°C. Fig.2(a) shows the distribution for a deposition at 375°C and Fig.2(b) shows at a higher magnification a large facetted island of Ge. Fig.3 shows a distribution of very fine islands from a 525°C deposition. A strong contrast is obtained from these islands which are at most a few ML thick and mottled structure can be seen in the background between the islands, especially in Fig.2(a) and Fig.3.

Azadirachtin (Aza) used as insecticide due to inhibiting growth of insects and preventing them from feeding on plants. To understand the effects of contamination of this insecticide on phototrophs, and to determine the responses of these organisms against these insecticides are extremely important in understanding how the ecosystem is affected. In this study, chlorophyll-a amount, OD 560 and antioxidant parameters (total SOD, APX, GR, Proline, MDA and H2O2) were determined in order to understand the effect of Aza on Arthrospira platensis Gomont. Aza was applied between 0–20 μg mL−1 concentrations for 7 days in the study. Enzyme analysis was conducted at the end of the 7th day. There was a statistically significant decrease in the absorbance of OD560 and the chlorophyll-a content in A. platensis cultures exposed to the Aza (0–20 μg mL−1) during 7 days due to the increase in pesticide levels. SOD activity decreased at 8, 16 and 20 μg mL−1 concentrations; GR enzyme activity showed a significant decrease compared to the control at a concentration of 20 μg mL−1. APX activity did not change significantly compared to control. The MDA content increased significantly at 16 and 20 μg mL−1 concentrations. The H2O2 content significantly increased at 12, 16 and 20 μg mL−1 concentrations (p < 0.05) while the free proline content decreased at 4 μg mL−1 concentration (p < 0.05). As a result, regarding the Aza concentrations used in this study may be a step to prevent pesticide pollution in the environment.

ABSTRACTFerroelectric oxide films have been studied for their potential application as integrated optical materials and nonvolatile memories. Electro-optic properties of potassium niobate (KNbO3) thin films have been measured and the results correlated to the microstructures observed. The growth parameters necessary to obtain single phase perovskite lead zirconate titanate (PZT) thin films are discussed. Hysteresis and fatigue measurements of the PZT films were performed to determine their characteristics for potential memory devices.
