[Vitamin biosynthesis by germinating seeds at low temperature and in overmoistened soil]

The distribution of farnesene and farnesene hydroperoxide in apples of different varieties was studied. The relationship between the content of these compounds and the pathological browning of the apple surface, scald was followed. It was shown that 1) farnesene and farnesene hydroperoxide were concentrated in the cuticle; 2) there was no distinct correlation between farnesene concentration and scald, 3) there was a direct correlation between the concentration of farnese hydroperoxide and scald development; 4) the factors that inhibited farnesene oxidation (antioxidants, low oxygen concentration, mineral oils--farnesene absorbers) slowed down the scald development during apple storage.
