Abstract
Levels of adenine nucleotides (ATP, ADP, AMP) and of inorganic phosphate in needles of Picea abies, representing different stages of development and of pollution dependence. Lyophilized needles of Picea abies (Kaelbelescheuer, southern Black Forest) were analyzed for their content of adenine nucleotides (ATP, ADP, AMP: AdN) and of inorganic phosphate (Psub(i)). The metabolite levels were related to needle age, vegetation period and degree of damage (chlorophyll content). The results were as follows: 1) With increasing needle age there is a general decrease in the total AdN-pool. This decrease is most pronounced in very young needles and occurs in both healthy and damaged tissue. 2) The ATP/ADP-ratio of damaged needle is significantly higher than that of healthy ones. 3) Both phosphorylation potential (ATP.(ADP.Psub(i))/sup -1/) and adenylate energy charge ((ATP + 0.5.ADP).(AdN)/sup -1/) are significantly reduced in damaged needles. This is due to relatively higher levels of Psub(i) and of AMP. The results, although incomplete and preliminary, indicate metabolic alterations which have been described for other tissues in response to pollution by photooxidants.
