Moreover the test we describe could be useful also as a model for the study of the bacterization process.谁在削木头 发表于 2025-3-30 21:45:16

In a similar manner, this strain was associated with a collection of rice mutants of cv Césariot. The most active mutant was n. 17. Three field experiments were performed associating strain 4B with Césariot生意行为 发表于 2025-3-31 04:40:59

A field trial was executed to compare biofertilization with azospirilla against N-fertilization. Significant responses to inoculation in the presence of a limited supply of N was obtained particularly for cv. WesCustodian 发表于 2025-3-31 12:28:17

Cosmid Cloning of Nitrogenase Structural Genes of Azospirillum Lipoferum, These genes were found to be clustered and organized in the same order as in .. (.HDK). After introduction into the respective .. ... mutants the cloned ...HDK (Ali .HDK) restored nitrogenase activity up to approximately 2% of wildtype.
