Abstract
Studying on the relationship between phenylalanine ammonialyase (PAL), polyphenol oxidase (PPO), superoxide dismutase (SOD) activities of tissue cultured plantlets of slash pine (Pinus elliottii Engelm.) and its disease-resistance, the PAL, PPO and SOD activities of the plantlets cultured in bottles and in greenhouse were measured. The result showed that after the plantlets were treated with brown-spot needle blight toxin, the PAL and PPO activities showed a positive correlation into disease resistance, and the SOD activity showed a certain degree of negative correlation at the 48-168 h.
