将干径粗度相近的2年生枳实生容器苗60株从田间移入温室（20～25℃）,以田间10株为对照.从2008年11月14日至2009年1月3日,每10d从温室随机搬出3株置于田间,研究枳叶片中Ptcor8的表达与枳生理落叶及环境温度的关系.结果表明,温室里的枳冬季不落叶;从温室搬至田间的枳,随着搬出温室时间的延后,其落叶期推迟;12月中旬后搬出温室的枳,即使经历冬季低温也不落叶.在落叶和未落叶的枳叶片中,均能检测到Ptcor8的表达,qPCR结果表明,Ptcor8的表达与枳的生理落叶无关,其表达量的明显增加与骤然降温和持续低温有关,与低温关系密切.

To study Ptcor8 expression related to the defoliation of Poncirus trifoliate Raf. and the temperature, 2-year-old seedlings of 60 potted Poncirus trifoliata Raf. with similar diameter, in the temperature-controlled chamber （20～25 ℃）, were transferred to the field every 10 d from the 14th November, 2008 to January of next year, meanwhile, another 10 seedlings were put in the field as the control. The Poncirus trifoliate Raf. seedlings in the temperature-controlled chamber and those transferred to the field after the 14th December were non-de...
