不同温度处理对杂种卡特兰开花的影响
Effects of different temperature treatments on flowering of Brassolaeliocattleya Sung Ya Green ‘Green World’
【摘要】 对卡特兰杂交种进行了不同温度处理,以研究温度对开花的影响。结果表明:杂种卡特兰花芽未分化期开始采用25/20℃(昼/夜温度)处理能够显著地促进开花,使盛花期提前56d,但开花率低,开花以单花为主;在萼片分化期开始采用25/20℃处理也能够显著地促进开花,使盛花期提前14d,开花以双花为主,并且花朵显著增大;花芽未分化期开始采用35/30℃的高温处理能够抑制开花,萼片分化期开始采用35/30℃的高温处理能够延迟开花,花期延迟14d;2次30/25℃处理的开花性状与对照无显著差异。
【Abstract】 Brassolaeliocattleya Sung Ya Green ‘Green World’was treated under different temperatures to study the impacts on flowering.When the temperature treatments began at the undifferentiation phase,flowering was significantly advanced under 25 /20 ℃ ,i.e.56 days earlier than that of control,but flowering rate was lower and single flowers were dominant.When the treatments began at the sepal differentiation phase,flowering was advanced for 14 days under 25 /20 ℃ ,the size of flowers was significantly increased and double flowers were dominant.The flowering were inhibited under 35 /30 ℃ when the temperature treatments began at the undifferentiation phase,while postponed for 14 days when began at the sepal differentiation phase;there was no difference between these two treatments of 30 /25 ℃ and the control.
