Physiology and Genetics of , Nodulating Chickpeas (, L.)tly used to separate fast- and slow-growing groups of rhizobia. These strains were diverse with regard to their growth rates on yeast extract-mannitol medium but all of them acidified this medium and the majority produced an acid reaction with serum zone formation on litmus milk. Low activities of n

The Role of Mycorrhiza in Improving the Establishment and Function of the ,-Legume System under Fielion and N.-fixation. Nitrogenase activity needs, in fact, 21 moles of ATP to reduce dinitrogen to ammonia. Thus, nodules often contain two to three times more P per unit of dry matter than the root on which they are formed. Additionally, legumes have a restricted root system compared to graminaceous
