摘要: 以矮牵牛(Petunia hybrida)重瓣豪放双瀑布、单瓣豪放梦幻、单瓣迷你地毯为研究对象,研究了温度对矮牵牛生长发育的影响。结果表明,矮牵牛生长发育最佳温度为16~25 ℃,且温度恒定于21~25 ℃区间株高、冠幅、侧枝、开花朵数增幅最大;温度处于25~35 ℃区间植株会发生徒长,开花朵数下降;温度高于35 ℃或低于15 ℃对矮牵牛的生长都有抑制效果,抗病性降低,叶片大面积萎蔫,甚至枯死。

Abstract: Taking Petunia hybrida double waterfall, single dream and single carpet as materials, the effects of temperature on the growth and development of P. hybrida were studied. The results showed that the growth and development of P. hybrida were influenced by temperature, the optimum temperature was 16~25 ℃, the plant height, crown width, lateral branches and the number of flowers increased the most at the constant temperature of 21~25 ℃, while the plants grew spindly and the number of flowers decreased when the temperature was 25~35 ℃. Temperature higher than 35 ℃ or lower than 15 ℃ inhibited the growth of P. hybrida, reduced disease resistance, large area of leaves wilting, or even dead.

Key words: Petunia hybrida, temperature, growth and development
