Пероксидазная активность в клетках листьев Fraxinus lanceolata Borkh. и Acer pseudoplatanus L. в связи с их устойчивостью к выбросам коксохимического предприятия

Abstract

Correlation of free and ion-combined fractions of peroxydase activity in leaves of Fraxinus lanceolata Borkh. and Acer pseudoplatanus L. was studied. It is revealed that in leaves of more tolerant to coke-chemical plant emissions A. pseudoplatanus activity of membrane-combined enzyme fraction is considerably higher than the free one; in leaves of non-tolerant F. lanceolata it makes up about half of summary activity. Under phenol fumigation impact and chronic injurious activity of coke-chemical plant emissions releasing of the part of membrane-combined peroxydase and its change into free fraction takes place.
