Description

<p>The short-day condition significantly affected the formation of bolting and the thickening and morphology of rhizome of Alisma orientale. Therefore, it was necessary to conduct the sowing and raising of seedlings in the high-temperature season. The seeds were sown on cell trays containing field soil on Jul. 17 (plot S-7.17), Aug. 12 (plot S-8.12) and Sep. 11 (plot S-9.11) in 2013, germinated in a few days and developed to juvenile plants to be settled for 2 months. These juvenile plants cultivated for 4 months from settled planting, formed 5.0±1.2 scapes at plot S-7.17 and 0.6±0.8 scapes at plot S-8.12; however, no scapes were formed at plot S-9.11. The rhizome at plot S-7.17 was the highest in dry weight (63.2±7.6g), and composed of a large amorphous rhizome and several small rhizomes, whereas, the plant at plot S-9.11 formed a large oval rhizome. All dry rhizomes at each experimental plot contained alisol A, alisol B and alisol B monoacetate. In future, based on these results the cultivation of A. orientale will be conducted on paddy fields in a warm region in Japan.</p>
