Induction of systemic disease resistance in carrot roots by pre-inoculation with storage pathogens.

The possibility of inducing systemic resistance to grey mould rot (caused by Botrytis cinerea) in carrot was investigated with roots stored at 1 deg C and preinoculated with storage pathogens. Pre-inoculating the bottom half of the roots with mycelial plugs of B. cinerea or Sclerotinia sclerotiorum decreased the amount of grey mould rot when the carrots were subsequently challenged with B. cinerea near the crown 25 d later. The effectiveness of the resistance-inducing lesions in providing protection was related to the amount of inoculum used for pre-inoculation. From these results it is suggested that the mechanisms of induced systemic resistance can be turned on at low temp. and thus could be used for increasing disease resistance in cold-stored carrots. This is the first report on induced systemic disease resistance in the Apiaceae.
