Stomata plays vital role for entry of plant pathogens. Plant pathogens like bacteria, viruses enter through stomata. In citrus also the stomata plays important role in infection of bacterial canker caused by Xanthomonas axonopodis pv. citri. Studies to investigate the role of stomata in bacterial canker infection were conducted under screen house condition on different stomata aspects like count, size (length and breadth) and pore size in different six different citrus genotypes. The observations were recorded on per cent disease intensity and incubation period. These observations were correlated with stomata factors. The stomata size, pore size and frequency were positively correlated and increased the per cent disease intensity. There was negative correlation between stomata factors and incubation period. Maximum ‘r’ value was observed in positive correlated stomata pore size and per cent disease intensity (0.768) followed by stomata width (0.764) and stomata length (0.714) whereas; minimum ‘r’ value observed in stomata frequency (0.230) which found positively non significant with per cent disease intensity. Highly significant but negative correlations were observed between stomata factors with incubation period. However, maximum ‘r’ value was observed in negative correlation between stomata pore size and per cent disease intensity (-0.786) followed by stomata length (0.714) and stomata width (0.764) whereas; minimum ‘r’ value was observed in stomata frequency (-0.230) which found negatively non significant with incubation period.
