通过对引进的玉杏、红丰、凯特、红太阳、大棚王等5个山东杏品种1年生枝条进行0℃、-25℃、-30℃、-35℃、-40℃等5个梯度低温和时间交互胁迫处理，测定各品种电解质渗出率、可溶性糖含量、游离脯氨酸（Pro）含量、丙二醛（MDA）含量的变化等相关的生理指标，以研究经抗寒性锻炼之后的各品种不同胁迫时间和胁迫温度在生理方面对各品种的影响。结果表明，电解质渗出率、可溶性糖含量、丙二醛（MDA ）含量和游离脯氨酸（Pro ）含量均随温度的降低而增高；5个优质杏品种的半致死温度分别为玉杏-41．65℃、红丰-35．33℃、凯特-34．38℃、红太阳-34．06℃、大棚王-31．40℃。抗寒力强弱顺序：玉杏＞红丰＞凯特＞红太阳＞大棚王。
通過對引進的玉杏、紅豐、凱特、紅太暘、大棚王等5箇山東杏品種1年生枝條進行0℃、-25℃、-30℃、-35℃、-40℃等5箇梯度低溫和時間交互脅迫處理，測定各品種電解質滲齣率、可溶性糖含量、遊離脯氨痠（Pro）含量、丙二醛（MDA）含量的變化等相關的生理指標，以研究經抗寒性鍛煉之後的各品種不同脅迫時間和脅迫溫度在生理方麵對各品種的影響。結果錶明，電解質滲齣率、可溶性糖含量、丙二醛（MDA ）含量和遊離脯氨痠（Pro ）含量均隨溫度的降低而增高；5箇優質杏品種的半緻死溫度分彆為玉杏-41．65℃、紅豐-35．33℃、凱特-34．38℃、紅太暘-34．06℃、大棚王-31．40℃。抗寒力彊弱順序：玉杏＞紅豐＞凱特＞紅太暘＞大棚王。

A research about effect of low temperature stress on treatment by time interation on introduced One-year-old Prunus armeniaca‘Yuxing’ ,Prunus armeniaca‘Hongfeng’ , Prunus armeniaca‘Kaite’ , Prunus armeniaca‘Hongtaiyang’ & Prunus armeniaca‘Dapengwang’ were conducted and while the temperature conditions were de-signed to (0 ℃ ,-25 ℃ ,-30 ℃ ,-35 ℃ ,-40 ℃);electrolyte leakage ,soluble sugar content ,MDA ,Pro were deter-mined;the effect of different stress time and stress temperature at physiological aspects of all varieties were studied . Result shows that :physiological electrolyte leakage ,soluble sugar content ,proline (Pro) content ,malondialdehyde aldehyde (MDA) content increase with the decrease of the temperature ;semilethal temperature of five superior vari-eties of apricot ( Prunus armeniaca‘Yuxing’ ,Prunus armeniaca‘Hongfeng’ ,Prunus armeniaca‘Kaite’ ,Prunus armeniaca‘Hongtaiyang’ & Prunus armeniaca‘Dapengwang’) are-41 .65 ℃ ,-35 .33 ℃ ,-34 .38 ℃ ,-34 .06 ℃ ,-31 .40 ℃ ,respectively .The descending order of cold-resistant ability is :Prunus armeniaca‘Yuxing’ > Prunus ar-meniaca‘Hongfeng’ > Prunus armeniaca ‘Kaite’ > Prunus armeniaca ‘Hongtaiyang’ > Prunus armeniaca‘Dapengwang’.
