Zinnia and Balsam are flowering plants with high economic importance in floriculture. Inoculation of the planting medium with a beneficial microbial consortium is an innovative approach to produce quality and healthy seedlings in floriculture. In the present study the influence of a microbial consortium of the arbuscular mycorrhizal fungus (AMF) Funneliformis mosseae and a plant growth promoting rhizobacterium (PGPR) Bacillus sonorensis on flowering plants Zinnia and Balsam in pro-trays under poly house conditions was investigated. Estimation of various plant growth parameters such as plant height, stem diameter, bio-volume index, vigour index, plant strength, fresh weight, dry weight and nutrient uptake was carried out to analyse the ability of the consortium to improve seedling growth. Microbial parameters such as mycorrhizal root colonization and spore count, and population of PGPR in substrate was also studied. The results suggested that inoculating the substrate in pro trays before sowing the seeds with the consortium increased plant growth significantly compared to the uninoculated plants.

Control of nutrients as nitrogen and phosphorus after discharge into lakes is necessary since it is difficult and costly to control within wastewater plants currently in China. This paper studied the cycling of phosphorus and nitrogen with water and sediments from two lakes in China. It is found that oxygen plays a critical role in regulating phosphorus and nitrogen cycling within water and sediments. Three different oxygenation methods including aeration, calcium peroxide and hydrogen peroxide were studied to control phosphorus and nitrogen in overlying water. In anoxic conditions, the P concentration in water increased from an average 14 microg/L to 115.2 microg/L for Xili Lake, and from an average 24 microg/L to 1,000 microg/L for Jinchun Lake. The concentration of ammonia increased under anoxic conditions, while the concentration of nitrate increased under oxic conditions. In anoxic conditions, the nitrate concentration decreased probably through denitrification. Both N and P accumulation processes can be controlled under the three treatments. The phosphorus removal efficiency from the water body was in the order of CaO2 addition > aeration > H2O2 addition, while controlling effectiveness for ammonia was in the order of aeration > CaO2 addition > H2O2 addition.

Thysanolaena maximaFunneliformis caledonium, Acaulospora laevis, Rhizophagus fasciculatus, Claroideoglomus etunicatum, Gigaspora margarita, Glomus bagyarajii, Funneliformis mosseae, Rhizophagus intraradices Ambispora leptoticha Claroideoglomus etunicatum(broom grass) is an ever green non-timber forest produce species. Pot experiment was conducted to screen and select the efficient arbuscular mycorrhizal fungi (AMF) for inoculating broom grass. Screening was done with nine different species of AMF ( and ). Plant parameters like height, stem girth, biovolume index, total plant dry weight, and mycorrhizal parameters like root colonization, spore number in the root zone soil, etc. have been recorded according to the standard procedures. Based on the important plant parameters like bio-volume index, total plant dry weight, and phosphorus uptake, it is concluded that is the bestAMF for inoculating broom grass.
