Abstract Ionizing radiation has extensive applications in agriculture for inducing mutagenic changes in major field crops, potential breeding purposes, varietal development and crop improvement. This study was conducted to test the efficacy of 0.8, 1.6, 2.4 and 3.6 kGy gamma irradiation doses (Cobalt-60) upon growth and yield performance of edible pea (Pisum sativum L.) in pot culture experiment during 2009. Results demonstrated that higher radiation doses (1.6 and 3.2 kGy) significantly influenced the studied attributes of P. sativum. It was observed that 3.2 kGy had detrimental effects on shoot and pod lengths of pea which were reduced by 14.60 and 17.71 % respectively when compared to control. Differential response of the number of seeds pod−1, 1000 grain weight and dry biomass of pea were recorded at the applied doses. Significant reduction in number of seeds (−14.21 %) but increase in 1000 grain weight (+13.93 %) and dry biomass (+11.32 %) of pea were recorded at 1.6 kGy which revealed stimulatory effects on grain weight and dry biomass. Conversely, radiation dose 3.2 kGy was found detrimental to all the studied parameters except number of pods plant−1 and number of seeds pod−1 which were not affected.

Nodulation of Pisum sativum cv. Afghanistan by Rhizobium leguminosarum strain Tom can be blocked by R. leguminosarum strain PF2 (isolated from P. sativum cv. Rondo) which does not form nodules of Afghanistan peas. We tested PF2 for its ability to produce bacteriocins and other compounds inhibitory to the growth of Tom. Neither strain was antagonistic toward the other. Similarly, there was no evidence for the production of inhibitors as the rhizobia grew in the plant rhizosphere. Apart from an already noted (Broughton et al. 1980. Can. J. Microbiol. 26: 562–565) ability of PF2 to accumulate on the root surfaces two to three times faster than Tom, we could not find a reason to explain the complete blocking of nodulation. In other experiments using PF2 (and Tom) killed by exposure to massive doses of gamma irradiation, dead cells still bound to the roots but they were incapable of blocking nodulation by living Tom. Finally, when both rhizobia were used to inoculate P. sativum cv. Rondo (they both form nodules on this plant), roughly one third of the nodules contained Tom, one third contained PF2, and one third contained both strains (i.e.,there was no evidence for competition). We conclude, therefore, that competition in this system is dependent upon live bacteria and requires cooperation from the plant.
