effect of phosphate solubilizing fluorescent pseudomonad and phosphorus fertilizer on growth and nutrient uptake of sesame
phosphate solubilizing bacteria are a group of plant growth promoting rhizobacteria (pgpr) that increase growth and yield of plant by enhancing insoluble phosphates. in this study, a greenhouse experiment was carried out to investigate the effect of phosphate solubilizing bacteria and phosphorous fertilizer on the yield and chemical components of sesame. this experiment was conducted in factori...
متن کاملNutrient Uptake by Intact and Disturbed Roots of Loblolly Pine Seedlings
1 Most measurements of nutrient uptake use either hydroponic systems or soil-grown 2 roots that have been disturbed by excavation. The first objective of this study was to 3 test how root excavation affects nitrate uptake. Rates of NO3 uptake by mycorrhizal 4 loblolly pine (Pinus taeda L.) seedlings were measured in intact sand-filled columns, 5 hydroponics, and disturbed sand-filled columns. T...
متن کاملEffects of Plant Growth-Promoting Rhizobacteria on Loblolly and Slash Pine Seedlings
Loblolly and slash pine seed were inoculated at sowing with 1 of 12 different strains of plant growth-promoting rhizobacteria (PGPR) in the greenhouse. Time to germination and seedling densities were determined at 21 days, and seedling biomass was measured at 12 wk after sowing. All bacterial strains significantly increased the speed of seedling emergence over nontreated pine seed. By 12 wk, ho...
متن کاملAluminum sensitivity of loblolly pine and slash pine seedlings grown in solution culture.
To probe variation in Al sensitivity of two co-occurring pine species, seedlings from six full-sib families of loblolly pine (Pinus taeda L.) and slash pine (Pinus elliottii Engelm.) were grown in solution culture containing 4.4 mM (high-Al) or 0.01 mM (low-Al) AlCl(3) at pH 4 for 58 days. On average, both pine species had 41% less total dry weight in the high-Al treatment than in the low-Al tr...
متن کاملLoblolly pine growth and soil nutrient stocks eight years after forest slash incorporation
Incorporation of forest slash during stand establishment is proposed as ameans of increasing soil carbon and nutrient stocks. If effective, the increased soil carbon and nutrient status may result in increased aboveground tree growth. Eight years after study installation, the impact of forest slash incorporation into the soil on soil carbon and nutrient stocks, foliar nutrients and loblolly pin...
