Utilization of organic phosphorus sources by oilseed rape, sunflower, and soybean
We evaluated the ability of Brassica napus L. [oilseed rape], Helianthus annus L. [sunflower], and Glycine max L. [soybean] plants grown inoculated with or without bacteria to utilize organic P sources. Plants were supplied with inorganic [dibasic sodium phosphate] and organic P sources [phytate and...

| 520 | |a We evaluated the ability of Brassica napus L. [oilseed rape], Helianthus annus L. [sunflower], and Glycine max L. [soybean] plants grown inoculated with or without bacteria to utilize organic P sources. Plants were supplied with inorganic [dibasic sodium phosphate] and organic P sources [phytate and glucose phosphate] at three concentrations and grown for 40 d under sterile conditions. Three inoculation treatments were compared: control [non-inoculated plants], inoculation with Bacillus amyloliquefaciens BNM340, and inoculation with Pseudomonas fluorescens BNM296 [two bacteria with proven phytase activity]. Oilseed rape, sunflower and soybean could utilize organic P sources. For example, when phytate [0.5 mM] P was used as the external P source, the increase factors over the no-P treatments were 4.5, 1.4, and 1.4 for oilseed rape, sunflower, and soybean P uptake, respectively. When glucose 1-phosphate disodium salt [G1P, 0.5 mM] was the P source, the increase factors were 8.8, 1.7, and 1.9 respectively. Positive responses to the organic P sources were found for the biomass accumulation of oilseed rape and soybean but not for sunflower. The inoculation with bacteria did not exert a promoting effect on P uptake. We demonstrate that the three species can effectively use organic P sources. The existence of crop plants that are more efficient in the utilization of different soil P sources would be particularly beneficial to improve P recycling and use of P fertilizers in agriculture. | ||
