PAL activity and organic components in basal stem phloem of poplar clones under waterlogging and flooding conditions



PAL activity and organic components in basal stem phloem of poplar clones under waterlogging and flooding conditions



Journal of Nanjing Forestry University 21(1): 51-55



Pot experiments with 3 poplar clones from the Aigeiros section under waterlogged conditions showed that in comparison with non-waterlogged controls, the activities of phenylalanine ammonia lyase (PAL) and the contents of organic components in the basal stem phloem of all clones tested changed significantly. Consideration of both growth and activity in the basal stem phloem, indicating that tolerance to water logging was in the order clone 'NL-80105' > clone 'NL-80351' > maternal clone 'I-69'.
