Metabolic changes in developing Cuscuta campestris Yunck seeds were studied with respect to TCA‐soluble phosphate fractions, nucleic acids and the enzymes, viz , acid and alkaline phosphatase, neutral and alkaline FDPase, starch phosphorylase, α‐amylase ribonuclease, deoxyribonuclease and phytase. RNA and DNA contents increased steadily, and then remained stationary during the last two stages. The activities of all the enzymes studied increased with development with a sharp fall in the final stage. Interestingly, α‐amylase was present throughout the seed development. Phytic acid (16% of the total P) does not seem to function as phosphate reservoir, instead orthophosphate (13% of the total P) and nucleic acids (30% of the total P) may serve this function.
