Progressive quantitative changes of caffeine and total nitrogen in the reproductive parts of Arabica and Robusta coffee
Studies on seven-year old Coffea arabica Linnaeus S.795 and C. canephora Pierre ex Froehner S.274 have revealed the presence of caffeine in the mature flower buds. The amount of caffeine and total nitrogen content declined in the faded flower and berry in the initial stages of development, but increased in the developing berry. These changes were proportionate to the dry matter accumulation in the reproductive parts. Caffeine and total nitrogen contents were positively correlated both in S.795 (r=0.9950) and S.274 (r=0.9892)
