Effect of inoculum concentration, age and degree of susceptibility of the host on bacterial leaf streak development

  • Published:
Proceedings / Indian Academy of Sciences

Abstract

Investigations on the effect of inoculum concentration, age and degree of susceptibility of the host on bacterial leaf streak development of rice revealed that lesion length has a linear relation with inoculum concentration and inverse relation with age of the host. Susceptibility and age of the host and inoculum concentration bear no relation with the incubation period except the lowest inoculum concentrations. However, there was a definite association between method of inoculation and incubation period. Lesion colour varied with the age of the host irrespective of the inoculum concentration.
