摘　　要：以早熟梨离体结果枝为试验材料,通过控制温度、光照条件以及喷施不同种类和浓度的生长调节剂生长调节物质来研究影响早熟梨芽休眠进程的因素。试验结果发现在25℃条件下在0.04%、0.08%的乙烯利和0.1mg/L和0.3ABAmg/L都能在一定时间内抑制萌芽,0.3mg/LIAA处理能促进萌芽,而0.6mg/LIAA和GA3处理效果不明显;而在15℃条件,所有处理的萌芽率都为0;试验结果还表明在1500Lx光照强度下光照时间对早熟梨芽休眠的影响效果不显著。The experiment was conducted with the bearing branch of early ripening pear cultivar and it studied the crucial factors influencing the process of bud dormancy through different temperature, different light condition and different kind and level of plant growth regulator. Results showed that when in 25 ℃2 0.04% and 0.08%ELS and 0.1mg/L and 0.3ABA mg/L ABA can inhibit and 0.3 mg/L IAA can tempt germination, but the effects of 0.6mg/L IAA and GA3 are inconspicuous; when in 15℃ the rate of germination of all the treatments is O.The results also showed that under the condition of 1500Lx the effect of the time of light on the dormancy of early ripening pear cultivar is inconspicuous.
