“…Total plant weight (W) was positively correlated with Nv (individual N levels) and N content (individual N levels and complete data set), (as found also by Rennie and Kemp, 1981) and negatively correlated with % N at NO and N10.5 level (Table 5). Nv was positively associated with Wn and N content.…”

Common bean, Phaseolus vulgaris L., is known to be 'inefficient' in nodulation and N2 fixation although it responds to applied nitrogen. An experiment was conducted to identify and to characterize bean cultivars nodulating in the presence of a high level of nitrogen.Sixteen cultivars and a check for inefficient nodulation, OAC Seaforth, were inoculated and grown for 40 days in replicated pots supplied with zero, 3.5 and 10.5 mM combined nitrogen as NO3 and NH2. Seven traits relating to nodulation and N2 fixation were all significantly affected by N level (N), cultivar (Cv) and N x Cv interactions (except for root dry weight), indicating that cultivars responded differently to the N treatments. Total dry weight (W) and shoot to root ratio (S/R) increased with the increased N levels. Nodule dry weight (Wn), visual nodulation score (Nv) and nodulation index (Nx) decreased as the N increased. Percent N and N content per plant increased with the increased N level. Plant weight (W) was positively correlated with Wn, Nv and N content and negatively correlated with %N. Nodulation score was positively associated with Wn and plant N content. Genotypes superior in nodulation and N2 fixation in the presence of N were identified. Cultivars Italian Barlotti, California Light Red Kidney, Kentucky Wonder A and Pueblo 152 were selected for further testing and use in improving the nitrate tolerant nodulating characteristic of bean.

“…Bean lines varied also for acetylene reduction, specific nodule activity and nodule mass (Graham and Rosas, 1977;Westermann and Kolar, 1978), and in peanut (Arachis hypogea L.) leghemoglobin content was found to vary (Schiffman and Lobel, 1970). These traits were correlated positively with total plant N content (Rennie and Kemp, 1981;Schiffman and Lobel, 1970), and therefore may be useful as selection criteria for improved N2 fixation. Most indirect measures of fixation show seasonal profiles that peak during the R3 growth stage (50% bloom) and decline thereafter (Nash and Schul-man, 1976;Schiffman, 1982;Westermann and Kolar, 1978).…”

Indirect measures of N2 fixation in common bean (Phaseolus vulgaris L.) under field conditions: The role of lateral root nodules

et al. 1989

The role of lateral root nodules in N2 fixation and the relationships between total shoot N and several traits which influence or control N2 fixation in common bean (Phaseolus vulgaris L.) i.e., acetylene reduction value, specific nodule activity, leghemoglobin concentration, total leghemoglobin and nodule mass, were investigated in field studies. Significant variation among bean lines was observed for all the traits measured. Lines varied for the proportion of total N accumulated up to the R3 growth stage, thus measurements of total shoot N near maturity (e.g., R7) provided a better estimate of total N2 fixation than measurements taken at an early growth stage. Nodule mass was correlated with acetylene reduction and total leghemoglobin, and total leghemoglobin was correlated with acetylene reduction value. Total shoot N at R7 was correlated with seasonal means of nodule mass and number, acetylene reduction value and total leghemoglobin. For all traits except total leghemoglobin, values for lateral roots were more highly correlated with total shoot N than were values for either crown roots or the whole root system. Seed yield was most highly correlated with nodule mass of the lateral roots. These results will be useful in devising breeding strategies for improved N2 fixation of the host plant.
