Relations between photoassimilation activity indices of leguminous plants and their symbiotic nitrogen fixation

Mikrobiologicheskii Zhurnal 52(6): 49-53

Relations between photoassimilation activity indices of leguminous plants and their symbiotic nitrogen fixation

The relations between symbiotic N fixation and indices of photoassimilatory activity were studied in Medicago sativa, peas, lupins and soyabeans. N fixation was positively correlated with leaf chlorophyll a content but this relationship was only observed in peas and M. sativa when the most effective strains of N-fixing bacteria were used compared with a mixture. In peas, soyabeans and M. sativa, leaf area was also higher with effective strains of N-fixing bacteria.
