对伊富高省旧Kiyyangan村2个沟内的12个样品进行了花粉、植物岩和淀粉分析，为大约810-750 calb.p的人类活动提供了证据。水稻（Oryza sativa）种子植物岩和胚乳淀粉与水生马铃薯（Potamogeton）花粉和海绵针状体遗迹相一致，为该遗址的水稻湿田种植提供了初步证据。最早的水稻遗迹出现在大约公元前675 cal.b.p.的阶地沉积物中。在大约530-470 cal. b.p.之后，这些遗迹显著增加，支持了先前的研究，表明该地区的水田水稻种植后期扩大。该研究代表了在菲律宾发现的O. sativa的原始、沉积物衍生的古代淀粉证据，以及该物种的原始、沉积物衍生的古代植物岩证据。
abstract:Pollen, phytolith, and starch analyses were carried out on 12 samples from two trenches in Old Kiyyangan Village, Ifugao Province, providing evidence for human activity from ca. 810–750 cal. b.p. Seed phytoliths and endosperm starch of cf. rice (Oryza sativa), coincident with aquatic Potamogeton pollen and sponge spicule remains, provide preliminary evidence for wet-field cultivation of rice at the site. The first rice remains appear ca. 675 cal. b.p. in terrace sediments. There is a marked increase in these remains after ca. 530–470 cal. b.p., supporting previous studies suggesting late expansion of the cultivation of wet-field rice in this area. The study represents initial, sediment-derived, ancient starch evidence for O. sativa, and initial, sediment-derived, ancient phytolith evidence for this species in the Philippines.
