 note = {Rhizomes of Curcuma alismatifolia Gagnep. were soaked with 100mg L<-1> GA_3 for 0, 3, 6, 12, 24 and 48 hours prior to planting on 17 March 2005 at Chiang Mai University, Thailand. The results showed that the rhizome soaking with GA_3 solution delayed the emergence of shoot. The GA_3-untreated control plants sprouted at 43 days after planting (6 weeks after planting (WAP)) while rhizomes soaked with GA_3 for 3, 6, 12, 24 and 48 hours prior to planting sprouted at 55 (8 WAP), 57 (8 WAP), 50 (7 WAP), 63 (9 WAP) and 70 days after planting (10 WAP), respectively. The application of GA_3 delayed the sprouting of shoot thus the increase in plant height, the production of leaves and the flowers were also delayed in the early stage. However, after 14 WAP the plant height and the number of leaves per a shoot became constant and those were not significantly different with the control plants. The rhizomes soaked with GA_3 for 48 hours gave the latest flowering at 122 days after planting (17.4 WAP) about 34 days (5 WAP) later than the GA_3-untreated control plants flowered at 88 days (12.5 WAP). The flower stalk and flower were elongated when the rhizomes are soaked in GA_3 solution prior to planting. During flowering stage for each treatment, the N, P and K content of the aboveground part and the underground part organs were determined. Result shows that rhizomes soaking with GA_3 had effect on the amount of K in aboveground part and P in underground part. By soaking rhizomes for 48 hours, the amount of K in the aboveground part was highest at 654mg, while the amount of P in the underground part is highest at about 120mg when the rhizomes were soaked for 24 hours., クルクマ・アリスマティフォリアGagnep.の塊茎を、植え込み0、3、6、12、24、48時間前に濃度100mg L<-1>のジベレリン（GA_3）水溶液100mLに浸漬し、2005年3月17日にタイ、チェンマイ大学で植え込んだ。塊茎のGA_3水溶液浸漬処理で萌芽が遅れた。GA_3未処理の対照植物では、植え込み後43日（6週間）で萌芽したが、3、6、12、24、48時間前にGA_3水溶液に浸漬した植物では、55日（8週間）、57日（8週間）、50日（7週間）、63日（9週間）、70日（10週間）に萌芽した。同時に、塊茎のGA_3水溶液浸漬処理で、生育初期の植物の草丈伸長が促進され、葉と花の形成も遅くなった。しかしながら、植え込み14週間後以降は、草丈およびシュートあたりの葉数は、対照区と処理区で差がなくなった。クルクマ塊茎を植え込み前48時間浸漬した処理では、植え込み後122日後（17.4週間後）に最初に開花し、対照区の88日後（12.5週間後）に比べて、34日間（5週間）開花が遅くなった。花茎と花は、GA_3水溶液に浸漬することで長くなった。開花期における地上部、地下部各器官の、窒素、リン、カリウム濃度と株当たり含有量を測定した。GA_3水溶液に浸漬した区では、地上部のカリウム含有量と地下部のリン含有量に影響を与えた。地上部のカリウム含有量は、GA_3水溶液に塊茎を48時間浸漬した区で654mgと最高値を示し、地下部のリン含有量と濃度は、GA_3水溶液に塊茎を24時間浸漬した区で120mgと最高値を示した。},
