摘要: Aruncus dioicus (Walter) Fernald (Rosaceae) is a perennial herbaceous plant whose young shoots are traditionally collected in the wild and consumed as food NE Italy. The aim of this study was to determine germination requirements its seeds order start cultivation, assess six accessions species. Viability ranged from 86 97% various accessions. Germination rate almost null two accessions, 10.5 37.3 other ones. seed coat permeable water. Treatments with GA3, KNO3 mechanical scarification did not enhance germination, while cold stratification treatment at 2 °C for different periods improved mean time compared untreated seeds. With 45 days stratification, (respectively, 90.1% 7.7 dd) were those Cold stratifie...
