Description:
The composition of coffee shade tree species and density of arbuscular mycorrhizal fungi (AMF) spores in Bonga natural coffee forest of southwestern Ethiopia were investigated. This study is the first report on AMF populations of Ethiopian natural coffee forests. The main purposes were to systematically identify the dominant coffee shade tree species, evaluate their densities and quantify and characterize populations of arbuscular mycorrhizal fungi particularly in the rhizosphere of coffee plants. Sample plots of 400m^2 with coffee plants and dominant shade tree species were selected. Sampling of soil was carried out at a depth of 0-15cm from the rooting areas of shaded and unshaded coffee plants for analysis of some soil parameters and quantification of AMF spores. Nineteen dominant shade tree species belonging to 14 plant families were identified in considered 10 quadrates. In terms of their stand dominance, Millettia ferruginea (Hochst.) Baker had the highest frequency of occurrence (22.3%) followed by O. welwitschii Friis & P.S. Green (15.5%). High density (503stems/ha) and/or percentage (66%) of Coffea arabica L. were recorded. All soil samples yielded AMF spores and the counts ranged from 4 to 67 spores 100g^-^1 of dry soil. Notably higher mean counts of AMF spores were found under leguminous shade trees compared to non-leguminous ones. AMF spore counts were significantly positively correlated with coffee counts and available soil P content. Five genera of AMF were identified based on spore morphology. Glomus dominated members of Glomeromycota. The other genera found were Gigaspora, Acaulospora, Entrophospora and Scutellospora in order of occurrence. The present investigation has documented species richness among dominant coffee shade tree species along with a fair distribution of relevant numbers and types (genera) of AMF to stimulate coffee growth. Thus, Bonga natural coffee forest seems to be an ideal focal forest for in situ coffee genetic resources conservation and promotion of organic coffee production.

Biocontrol of Root-Rot Disease Complex of Chickpea: By Arbuscular Mycorrhizal Fungi and Other Phosphate Solubilizing Microorganisms
Biocontrol of Root-Rot Disease Complex of Chickpea: By Arbuscular Mycorrhizal Fungi and Other Phosphate Solubilizing Microorganisms
Soil provides an excellent niche for the rhizosperic microorganisms and seems to be the hot-spot for the microbial interactions. Among the soil microorganisms Arbsucular mycorrhizal and other phosphate solubilizing microorganisms can promote the plant growth and also very effective against the soil borne diseases. The mycorrhizal fungi have the ability to improve plant vigor, soil quality and also play a crucial role in nutrient uptake, water relations, ecosystem establishment and the productivity of plants. Similarly, phosphate solubilizing microorganisms can profoundly, improve the seed germination, root development, and water uptake by plants. Beside this they can also improve the nutrient uptake or indirectly by changing the microbial balance in favour of beneficial microorganisms in the rhizosphere and can suppress the broad spectrum of plant borne plant pathogens. Considering the importance of these symbionts in the plant disease protection, it came into highlight for research that the combined application of these microorganisms is more beneficial than use of single agent and provides a better management against the soil borne plant pathogens.

Description:
A field survey of metal concentrations and arbuscular mycorrhizal (AM) components of plants growing on five mining sites was conducted in Chenzhou City, Hunan Province, Southern China and a control site in Hong Kong. Significant differences were observed in the average concentrations of total heavy metals (Pb, Zn, Cu, Cd) and one metalloid (As) in contaminated soils compared with the control site. Gramineae and Compositae were the dominant plant families growing on mine tailings, with Chrysanthemum moritolium (common chrysanthemum), Cynodon dactylon (Bermuda grass), Miscanthus florodulus (Sword grass) and Pteris vittata (Ladder brake fern) commonly found at all sites. AM fungal colonization was detected in most of the plants. Comparing the four common plant species, three components of mycorrhizal colonization (arbuscules, vesicles and coiled hyphae) were found in the roots of C. dactylon and P. vittata growing at Do Shun Long (DSL) mine site. Concentrations of As in fronds were 24-fold higher than in roots of P. vittata with the highest mycorrhizal colonization rate (73%) among all sampling sites. Extensive mycorrhizal colonization (85%) was also recorded in the roots of C. dactylon with As accumulation 57 times higher than in shoots. The four common plants found in metal contaminated sites had developed different strategies for survival in the contaminated sites with the aid of indigenous AM fungi.

Pierre-Joseph Redouté, 1759 – 1840, was a Belgian painter and botanist, known for his paintings of the roses, lilies and other flowers at Malmaison. Redouté was born in Belgium. He was an official court artist of Queen Marie Antoinette, and he continued painting through the French Revolution and Reign of Terror. Redouté survived the turbulent political upheaval to gain international recognition for his precise renderings of plants.

9GreenBox – Adenium Desert Rose Perfume House Plant Bonsai
- Desert Rose is one of our ultra favorite plants. Native to arid areas of Africa including Madagascar, Tanzania, Kenya and Uganda, it is related to the Plumeria
- This plant deserves FAR more appreciation. Desert Rose is excellent in pots especially for people who “kill everything” as the Adenium obesum lives with little care and can take a good deal of neglect.
- The coolest hybrids are produced in China, Taiwan and Thailand, and maybe India. Enjoy our personal desert rose collection.
- The plant will produces LARGE 6.5cm flowers.
one plant 5-7 inches tall that is
well-rooted in a 4 inch pot similar to the one in the second photo.
will ship without soil and pot. The diameter of this plant caudexes is about 4-6cm (sometimes it has multiple branches) .and should be planted soon upon arrival .

Description:
Arbuscular mycorrhizal fungal (AMF) colonization and nodulation of groundnut were examined in nine soils collected from subsistence farmers’ fields in Zimbabwe. Nodule number, shoot dry weight, shoot N and P contents, and AMF colonization were assessed after 6 weeks growth. Both nodule number and AMF colonization differed by an order of magnitude among the nine soils. Soil available P explained almost all the variability in nodule number (r^2=0.98), but had no significant effect on percent AMF colonization. By adding P to one soil, nodule numbers increased four-fold resulting in a significantly higher N content in the shoots. Similar, but smaller, effects were obtained by increasing the abundance of AMF through an inoculation with Glomus intraradices, suggesting that nodulation in this soil was limited by AMF abundance and that the fungi could, to a limited extent, substitute for P fertilizer.
