Flower bud differentiation occurred at 23 days and bloomed 44 days after sowing in the greenhouse from April to June. Flower bud was axillary and developmental stages of nasturtium were divided into 6 stages : (I) differentiation stage, (II) sepal differentiation stage, (III) stamen differentiation stage, (IV) petal differentiation and stamen formation stage, (V) petal formation stage, (VI) pistil development stage and flower opened. The elongation of petal was delayed as compared with the stamens. Numbers of flowering and growth were severely inhibited at 30/25℃. Flower bud development stopped from the sepal differentiation stage to the stamen differentiation stage because of blind induced by high temperature., E, 3, KJ00004019115, 論文, Article}, pages = {71--75}, title = {ナスタチウムの花芽発達過程と開花に及ぼす温度の影響}, volume = {50}, year = {}, yomi = {ノグチ, アリサ and イチムラ, マサシ} }
