| 摘 要： | 目的]为进一步调控杜鹃花期提供理论和实践依据。方法]以杜鹃花早花品种寒牡丹、中花品种肉桂和晚花品种雪里藏松为试材,研究了不同时期低温处理(0～10℃,分别为35、70、105d)对杜鹃花生长和开花的影响。结果]随着低温处理天数的增加,寒牡丹的透色期、初花期、末花期相应延迟,开花时间比对照略有减少,3种低温处理对其花径大小影响不大。35d低温处理能提前肉桂花期,105d低温处理使其花期明显延后且开花时间减少,3种低温处理均使花径增大。35d低温处理中雪里藏松的开花状况与对照相同,继续低温处理则花期提前,花径变小。结论]在丹东地区,早花品种花期的延迟可以采用35d以上的低温处理,中花品种可以采用70d以上的低温处理,晚花品种花期提前则需采用70～105d以上的低温处理。

| Abstract: | Objective] The study aimed to supply theoretical and practical basis for regulating flowering stage of azaleas. Method] Taking the early flowering variety of azaleas cold peony, mid-mature flowering variety cinnamon and late-mature flowering variety Xuelicangsong as test materials, the effects of low temperature treatments (0~10 ℃) for different periods (35 d, 70 d and 105 d, respectively) on the growth and flowering of azaleas were studied. Result] The coloring period, first flowering period and last flowering period were delayed along with the increase of low temperature treatment days and the flowering time slightly reduced compared with that of CK. The three low temperature treatments had few influence on flower diameter. Low temperature treatment for 35 d could advance the flowering of cinnamon and for 105 d could delay flowering obviously and reduce flowering time. The three low temperature treatments all increased flower diameter. In low temperature treatment for 35 d, the flowering status of Xuelicangsong was the same as that of CK. If treatment going on, the flowering advanced and flower diameter reduced. Conclusion] In Dandong area, low temperature treatment for 35 d could be used to delay flowering of premature flowering variety, for over 70 d could be used to delay flowering of mid-mature flowering variety and for 70~105 d could be used to advance flowering of late- mature flowering variety. |
