Therefore, German chamomile could be designated as a quantitative long-day plant. Also, budding and flowering were accelerated at high temperature of 30/25℃ (day/night). Reduction of light intensities by shading had the effect of retarding flower bud development, especially in the lot reduced into 25% of full sun light. Flower bud differentiation and development was observed by scanning electron microscope. Floral stages of German cbamomile were divided into 10 stages 0) Vegetative stage, 1) Pre-differentiation stage, 2) Involucre differentiation stage, 3) Later stage of involucre differentiation, 4) Early stage of floret formation, 5) Later stage of floret formation, 6) Early stage of petal formation, 7) Middle stage of petal formation, 8) Later stage of petal formation, 9) Flower opened. At stage 5, budding was observed., E, 4, KJ00004074203, 論文, Article}, pages = {268--273}, title = {ジャーマンカモミールの開花に及ぼす日長,温度及び光強度の影響と花芽分化過程}, volume = {47}, year = {}, yomi = {ノグチ, アリサ and トミタカ, ヤイチベイ} }
