Abstract Fats, nitrogenous and phosphorus compounds decrease in gametophytes, while total sugars, reducing sugars, total nitrogenous and phosphorus compounds and α amino nitrogen increase in embryos of seeds of the Taiwan red pine ( Pinus taiwanensis Hayata) and the Chinese fir ( Cunninghamia lanceolata (Lamb) Hook.) during germination. Lipase activity first increases during the early stages of germination and then decreases, while invertase activity increases continuously during germination. Qualitative changes in sugars, α-keto organic acids and amino acids in the seeds of both species were observed during germination. Forest Sci. 19:297-302.
