Changes of pectin content in alfalfa plants after inoculation with vascular wilt pathogens

摘要: Summary Alfalfa plants at the age of six weeks were inoculated with conidia and mycelium suspension Verticillium alboatrum or cell Corynebacterium insidiosum . The resistant susceptible strains, i.e., seed progenies clones, through overground parts roots. Changes in pectin content determined roots plants. total was spectrophotometrically. It found that changes after their inoculation above-mentioned pathogens much more significant than ones, especially early stages pathogenesis. increase decrease (but not extent changes) influenced by way inoculation,
