Lokman Shamsudin, . Photosynthetic quotient relationship to inorganic nitrogen of rivers in Trengganu. pp. 78-82. ISSN 0126-6128
Abstract
Photosynthetic quotient (P.Q) values with depth o f rivers in Trengganu were found to be lowered by high levels of indigenous amm onium nitrogen ranging from 1 .2 -0 .8 contrary to temperate conditions where high levels o f nitrate increase the P.Q values from 1.5 to 2.0. This is attributed to the fact that nitrate in lieu of ammonia produces two extra molecules of oxygen per atom of nitrate nitrogen assimilated culminating in higher P.Q values. Nevertheless the present findings tally well with that of marine phytoplankton (ie. P.Q is 1.2) when ammonia is the prime source of nitrogen.
