【Abstract】

<正>Shot-hole borer(SHB) Xyleborus fornicatus infestation of tea Camellia synensis involves the ectosymbiotic ambrosia fungus Monacrosporium ambrosium.Chitin,a common constituent of fungal cell walls and exoskeletons of arthropods,is a linear polymer of P -1,4-linked N-acetyl glucosamine.Organisms composed of chitin produce chitinases.Chitinases do not occur naturally in plants but plants may produce chitinase to defend themselves from microorganisms and insect predators.We have been studying the biochemical factors responsible for differences in susceptibility of tea clones to SHB attack.Since SHB and the fungus both contain chitin it was of interest to compare chitinase enzyme activity in stems of the susceptible and resistant tea clones TRI 2025 and TRI 2023 respectively.
