Phosphorus Mobilisation and Immobilisation Vary in the Root Environment of Different Barley Genotypes with Different Phosphate Sources

摘要: ABSTRACTA method was developed to estimate root efficiency of barley (Hordeum vulgare L.) in making available phosphorus (P) from various unlabelled, sparingly-soluble compounds containing P. The post-treatment is based on axenic germination a P-free medium, removing the seedling medium and incubating P substance be tested situ followed by soluble determination. Seven lines landrace were with 8 day old seedlings. CaHPO4 found dissolved five lines, while two them average immobilized phosphate (dissolved less than controls without plant) significant differences between (p < 0.01). acidification correlated significantly (rs = 0.727; p 0.001) level CaHPO4. On average, FePO4 all though 0.01), showed negative correlation mediu...
