Vaccinium (Ericaceae). With fresh seed light promotes germination but is not essential. The effect of light was eliminated by DS for 6 m in V. globulare germ. 70L(83% in 2-4 w), 70 GA-3(100% in 2nd w), 70D(10%), 40- 70D(47% in 2-8 w), and 14% in May in OT. The stimulation by light dtsappeared after DS, and seeds DS either 6 m or I y germ. 50% in 2-5 w in either 70D or 70L.
