  • The organoleptic properties of granule tea was optimized for granulation of Polygonatum sibiricum Delar(Dunggulle) tea for exclusion of scorched smell and increase of consumption. The length of 2 mm was suitable to cutting size of Dunggulle for preparation of the roasted Dunggulle. The optimum sensory conditions for aroma of Dunggulle granule tea showing 7.85 organoleptic score were 80.61% in ratio of Dunggulle extracts to total extracts, 12.77% in content of total extracts and 37.33% in rate of glucose to total sugar. The highest score of overall palatability was 5.96 at 61.11% in rate of Dunggulle extracts to total extracts, 13.79% in content of total extracts, and 60.92% in rate of glucose to total sugar.

  • Morphological characteristics and growth patterns of 20 Polygonatum collections indigenous to Korea were examined and the collections were classified to obtain the basic data for practical use of Polygonatum genetic resources. Based on the cluster analysisi 20 collections were distinctly classified into seven groups with average distance greater than 0.6 between groups. Group I was p. sibiricum Delar, and group II included p. odoratum var. pluriforum Ohwi, P. odoratum var. pturiforum Ohwi 'Variegata' and P. odoratum var. maximowiczii Koidz.. Group III was P. odoratum var. thunbergii Hara, group IV included P. lasianthum var. coreanum Nakai, and group V was P. involucratum Maxim. and P. desoulavyi Komarov. group Ⅵ was P. inflatum Komarov and group Ⅶ was P. humile Fischer ex. Maxim. Morphologically, group I was larger than the other groups, group II and III were medium, and group IV to Ⅶ were small. In the classification of genus Polyognatum, stem length, stem habit, phyllotaxis, stem angularity, petiole, inflorescence, perianth, bract and rhizome were particularly important characters. Group I to III were thought to be useful as the edible and medicinal resources plants, and group IV to Ⅶ were thought to be useful as ornamental plants.
