Effects of high temperatures in summer (HT) on subsequent extension growth and flowering of 'Jimba' were studied in controlled environments. After the plants exposed to HT were grown at 20°/10℃ (light/dark) with a 12-h photoperiod plus a 4-h night break, they showed inhibition of flowering under short-day conditions at 20°/15℃, compared to the plants isolated from HT. This shows that exposure to HT induces subsequent inhibition of flowering under low temperature conditions. 'Jimba' showed little reduction of stem elongation after exposure to HT, although exposure to HT induces both subsequent inhibition of flowering and stem elongation in many cultivars. This shows that inhibition of flowering and stem elongation under low temperature conditions by exposure to HT are independently regulated.}, pages = {1--7}, title = {栽培ギク '神馬' において夏季の高温遭遇は低温条件下での開花遅延を引き起こす}, volume = {8}, year = {2008}, yomi = {スミトモ, カツヒコ and ドウゾノ, ミツル and ヒサマツ, タモツ and シバタ, ミチオ} }
