Conservation of these populations is an emerging issue. However, basic data for the number of seeds per cone and the proportion of filled seeds are limited. Therefore, we described the traits of seeds collected in 2010-2014 from a small population located in the Arakashizawa area, in terms of the number of seeds per cone and the proportion of seeds that sink, which are substitutes for the proportion of filled seeds. The tree density of Pinus palviflora var. palviflora may have been considerably lower than that shown by a population in good condition. One mother tree, Arakashizawa-13, exhibited a high level in the proportion of seeds that sink. The selfing rate of seeds collected from this mother tree was extremely high. Selfed seeds would, therefore, be filled seeds for this mother tree.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"148201","nameIdentifierScheme":"WEKO"}],"names":[{"name":"Yonemichi,
