Abstract
Experiments on the effect of ultraviolet radiation on the anthocyanin content of the fruit pericarp were carried out in order to elucidate the causes of the inhibition of fruit-coloring in common eggplant (Solanum melongena L, var, esculentum Nees) occurring in some cases of“plastic house”cultivation.The content of anthocyanin was decreased by covering the plants or fruits using films having an extremely low transmittance in ultraviolet region, regardless of the kind of film material. This fact was recognized in cases when covering was made to the whole plant by means of “house” cultivation (Fig. 1, Tables 1 and 2) as well as when only the fruit itself was covered by an envelope (Fig. 2 and 3, Tables 3 and 4) .There was no clear correlation between the light transmittance of covering material and the anthocyanin content in the pericarp (Fig. 2, Table 3) . A close correlation was, however, found between the ultraviolet transmittance of covering material and the anthocyanin content in the pericarp when polyvinyl chloride films were used for fruit-covering (Fig. 4) .Supplemental irradiation of ultraviolet to the fruit promoted the anthocyanin formation in the pericarp (Table 5) .
