Linum (Unaceae). The yellow flowered Linums centering around L. bulgaricum because good germination was achieved, in 70L(72% in 4-14 d), 70D(28% in 4-22 d), 89% in April in outdoor treatment, and 40(25% in 6-11 w)-70-40-70. In this last experiment the remaining seeds were not dead even after the four cycles, because when treated with GA-3 at 70, 87% of the remaining seeds germ. in 5-7 d.
