Lonicera (Caprifoliaceae). All seeds are in berries and were WC for 7 d. Treatment with GA-3 was tried on L. tatarica germ. best with fresh seed in 70(100% in 2nd m) and less conveniently in 40(14%)-70(85% in 3rd m). DS 6 m at 70 reduced germination to 70(68%) and 40-70(81%) with similar values for seed DS 6 m at 40. Seed left on the bushes until January had much lower and more extended germination. .
