An experiment had been done in split design with 4 replicates in RasSudr Research Station, Desert Research Center, at South Sinai Governorate, Egypt, through 2009 on four years old Prosopis Chilensis to evaluate the effect of inoculation with Bradyrhizobium japonicum, Azotobacter chroococcum, Bacillus megatherium (PDB) and +VA mycorrhizae singly or in combination with vegetative (plant height, stem diameter and number of branches) and pod production (pod number/plant and pod weight/plant) and some chemical constituents total flavonoid). Results indicated that different biofertilizer treatments and their interactions significantly increased prosopis yield (pod number and pod weight), chemical analysis of leaves and branches (total carbohydrates, digestive protein, total digestive nutrients and total flavonoids) and chemical constituents of pods (crude protein, ash%, total carbohydrate, total sugar, total flavonoid and macro and microelements). Mixed inoculation gave better results than single ones, inoculation treatments can be arranged in descending order as follow, quarto inoculation, triple inoculation, double inoculation double inoculation and finally single inoculation. ª 2014 Production and hosting by Elsevier B.V. on behalf of Faculty of Agriculture, Ain Shams University.
A field experiment was carried out during two successive seasons, 2006 and 2007 on Prosopis chilensis at six month old transplants. Experiment was conducted in RasSudr Research Station, Desert Research Center, at South Sinai Governorate, Egypt. Aiming to study the effect of adding biofertilizers Bradyrhizobium spp., Azotobacter chroococcum, Bacillus megaterium and vesicular arbuscular mycorrhizae (VAM) as well as their interaction, viz. control (without microbial inoculation) on soil microbials counts, plant growth parameters, total chlorophyll and some chemical contents of leaves and branches. Results revealed that different biofertilizer treatments increased the microbial counts (total microbial counts, azotobacter, azospirilla, phosphate dissolving bacteria (PDB) and VAM), the growth parameters (plant height, stem diameter, initiative branching point, number of branches, fresh weight and dry weight) and some chemical constituents such as total chlorophyll, crude protein, crude fiber and ash% compared to untreated plants. Concerning to inoculate plants with biofertilizers interaction treatments, a mixture of bradyrhizobium, azotobacter, PDB and VAM was the most effective in raising the productivity of prosopis plants followed by triple inoculated treatments, then double inoculation treatments and finally single inoculation treatments compared to control treatment. ª 2014 Production and hosting by Elsevier B.V. on behalf of Faculty of Agriculture, Ain Shams University.
nion (Allium cepa) and Barley (Hordeum vulgare) colonized by Glomus mosseae, G. fasiculatum, and G. intraradices were grown in aeroponic cultures. After 14 weeks, all roots were colonized by the inoculated vesicular-arbuscular mycorrhizal fungi. Abundant vesicles and arbuscules formed in the roots, and profuse sporulation was detected intra-and extra-radically. Within each fungal species, barley contained significantly more roots and spores per plant than onion did, although the percent root colonization was similar for both hosts. Mean percent root colonization and sporulation per centimetre of colonized root generally increased with time, although with some treatments colonization declined by week 14. Spore production ranged from 4 spores per cm of colonized root for G. fasiculatum to 51 spores per cm for G. intraradices. Infectivity trials with root inocula resulted in a mean ranged from 28.9 to 51.1% of onion roots colonized by G. mosseae, G. fasiculatum, and G. intraradices, respectively, while in aeroponic culture it ranged from 33.8 to 38. However, infectivity studies comparing G. fasiculatum spores from soil and aeroponic culture indicated no biological differences between the spore sources. Aeroponically produced G. mosseae and G. fasiculatum inocula retained their infectivity after cold storage (4°C) in either sterile water or moist vermiculite for at least 4 and 9 months, respectively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
