This study investigated arbuscular mycorrhizal fungi (AMF) inoculation and phosphorus fertilizer on growth, productivity and quality of onion grown under saline soil conditions. The experiment was conducted in the Experimental Farm of Desert Research Center, Ras Sudr, South Sinai Governorate, Egypt. Egyptian local onion cultivar ‘Giza 20’ was selected. Treatments were: two arbuscular mycorrhizal fungi (AMF) inoculation treatments [without inoculation (–AMF) and with mycorrhizal inoculation (+AMF)] and four phosphorus supplied treatments (0, 48, 96 and 144 kg P2O5 ha–1). Mycorrhizal inoculation and phosphorus addition affected the plant growth, bulb yield and quality. Morphological traits of plant (height, leaf number, fresh and dry weight), neck diameter, bulb characters (diameter and weight), total soluble sugars (TSS), protein, P content increased, while proline content decreased due to the inoculation of AMF and phosphorus application. Onion inoculated by AMF combined with 96 or 144 kg P2O5 ha–1 gave the highest productivity under saline conditions.
The field experiment (2009–2012) was conducted to assess the influence of different biofertilizers (AMF liquid/granular inocula, humic and seaweed extracts) on the growth and yielding of ‘Topaz’/M.26 apple planted on SARD soils in Poland. During conversion to organic orchard trees’ growth, fruit yield, their quality indices as well as nutritional status of leaf and fruit was ascertained. Fruit polyphenol content and their free radical scavenging activity were assessed. Moreover, the mycorrhizal root parameters (mycorrhizal and arbuscules frequency) were also presented. The most vigorous trees were inoculated with liquid inocula MicoPlant M and MicoPlant S. The plants treated with MicoPlant S gave the highest total yield (12.12 kg/tree) and revealed the best productivity (> 1 kg cm-2) as well as the average fruit weight. The liquid suspended inocula were more effective than granular one in terms of mycorrhizal root colonisation. Investigated biofertilizers increased P, K and Cu content of leaf. Organic soil extract (HumiPlant) decreased P and K content of fruit, while seaweed extracts (AlgaminoPlant) increased Ca amount of fruit. These treatments had the lowest K:Ca ratio. Used biofertilizers influenced apples polyphenol content as well as their antioxidant status.
A study was conducted to investigate the ability of arbuscular mycorrhizal fungi (AMF) in enhancing the growth and control of a root rot caused by different isolates of Fusarium oxysporum in sweet pepper seedlings. The plants were grown in plastic pots filled with sterilized horticultural soils. There were four treatments applied as follows: Fo (seedlings infected with fungus), M (seedlings inoculated with mycorrhizal fungi), Fo + M (seedlings inoculated with mycorrhiza and infected with fungus) and control. A randomized experiment was used and the growth, disease index, and photosynthetic activity of the plants were measured after 4 weeks. The investigations showed that the mycorrhizal inoculation had a protective effect on the F. oxysporum-infected pepper seedlings. The plants were characterized by a higher growth rate and a lower disease index than those growing only in the presence of the pathogenic fungus. The roots inoculated with mycorrhizal fungi were better developed than those infected only with F. oxysporum. The mycorrhiza contributed to an increase in the photosynthetic activity of the pepper seedlings.
Mycorrhizal fungi are gaining interest in the floriculture sector due to the beneficial effects on a crop performance and ornamental quality. The aim of the current study was to assess the effect of inoculation with the arbuscular mycorrhizal (AM) fungi Rhizophagus irregularis on ornamental quality of Begonia × semperflorens-cultorum grown in two different protected cultivation systems: a shadehouse or glasshouse. The inoculated plants incurred a significant increase of plant height by 34.6%, lateral shoot length by 27.9%, number of lateral shoots by 41.2%, number of flowers per plant by 102.9%, flower diameter by 27.5%, and stems dry weight by 263.6%. High temperatures in the glasshouse negatively affected the AM root colonization. On the contrary, shading induced higher mycorrhizal colonization (48.6%) and increased plant height, number of lateral shoots, number of flowers per plant and flower diameter compared to the glasshouse environment. Taking all together, our results clearly demonstrated that mycorrhizal inoculation at transplanting and shading may be beneficial to floriculture growers wishing to produce high quality B. semperflorens-cultorum plants during the spring-summer season.
