VAŘEKOVÁ I., TICHÝ V. (1977): The significance of riboflavin in the fruit-body formation in Lentinus tigrinus (Bull. ex Fr.) Fr. Česká Mykologie 31(4): 214-222 (published: 1977)
abstract
The optimum illumination level for the differentiation and growth of the fruit-bodies of Lentinus tigrinus is 300 lx. Riboflavin enhances the translocation of plastic substances to the differentiated fruit-bodies and inhibits the weight increase of the primordia. The effect of riboflavin may be expressed by the ratio of the weight of the fruit-bodies to the weight of the primordia (F:P). This ratio is a sensitive indicator even when the weight of the fruit-bodies increases with the weight of the primordia. Kinetin acts on the differentiation and growth of the fruit-bodies analogously from the viewpoint of quality. In comparison with riboflavin, considerably higher concentrations of kinetin are needed for producing the same effect. The effect is not greater when the two substances are applied together; on the contrary, it is less marked than the effect of either of the two substances applied separately.
