Parthenocissus (Vitaceae). P. tricuspidata germ. best in 70(98% in 2-6 d) and 40(98% in 7-14w) using seed that had been DS 6 rn at 40 or 70 in the dried berry and WC 7 d before sowing. Fresh seed germ. less as shown by 70(41%) and 40(92%). Fresh seed is more difficult to wash than dried seed, and this maybe a factor.
