Variation in the content of hypericins in four generations of seed progeny of Hypericum perforatum somaclones.

Abstract excerpt

The content of hypericins in in vitro regenerated Hypericum perforatum plants (R (0)) and four generations of their seed progeny (R (1)-R (4)) was compared. The mean content of hypericins in field-grown plants over the period 1992-2002 gradually increased under selection, and in the R (4) generation it was almost seven-times higher than that in the R (0) somaclones. Significant difference between hypericin...
