溫度對宿根滿天星生長與開花之影響
Effect of Temperature on Growth and Flowering of Gypsophila Panyculata cv. Bristol Fairy
摘要
並列摘要
Effect of temperature on growth and flowering of Gypsophila paniculata cv. Bristol Fairy were studied. High flower qualities was obtained at day/night temperature of 25/20℃. Although high temperature (30/25℃ or lowland in summer) promotes early flowering, the plants are dwarf with short flowering stems and malformed flowers. Plants grown at 20/15℃ remained rosette after 7 months. It was found that decreased night temperature from 30/25℃ to 30/20 or 30/15℃, increased fresh and dry weight in tops and roots, flower number, and decreased the percentage of malformed flowers, The optimum temperature for photosynthesis is around 25℃. The respiratory rate is high at 30℃ (639 µl O2/gm•hr ) and the Q10 from 20℃ to 30℃ is 3.5.
