Borodaj V. Rots of carrot and resistance to them during the storage recognized and promising varieties in the right-bank Forest-Steppe of Ukraine

Rots of carrot, resistance and susceptible varieties. Biological basis ground of the roades and methods of decrease of the waste of carrot from disease during the storage. Laboratory, microbiological, vegetative, statistical. Ecological and biological features, prevalence and harmfulness of the roots were studied. The evaluation of recognized and promising carrot varieties as to their resistance to the group of parasites has been conducted. The effectiveness a series of efficiency of treat-ments of carrot from disease was studied. Close connection between resistance of carrot varieties to the disease and anatomo-morphological indications, group of biochemical compound was established. Physiologo- biochemical changes in the carrot during the storage on resistant and susceptible varie-ties was investigation. For the first time terminal type of the sclerotia formation of S.sclerotiorum was discovered. It was proved, that microconidies of S.sclerotiorum may be sourсe of infection. For forcasting elaboratio n of treatments of carrot from disease. Biology, agriculture.
