摘要
将7个品种的油豆角进行5℃低温处理,处理7d,通过对它们的根系活力、脯氨酸含量、丙二醛含量、过氧化物酶活性及叶绿素含量的测定,来比较研究低温处理对不同品种油豆角的影响。研究表明:不同品种的低温反应不同,太空的耐低温性最强,超纯的耐低温性是最弱的,其余品种,介于它们之间。
The chilling tolerance of 7 varieties of snap beans was identified by the indexes including root activity,protine content, MDA content, chlorophyll content and POD activity, through the snap beans were treated under the low temperature at 5 ℃ for 7days. The results were as follows. 7 varieties of snap beans were different in the indexes. ＂Taikong＂ had a better chilling tolerance than that of others under 5 ℃. ＂Chaochun＂ low temperature of the resistance was the weakest, the remaining varieties range was between them.
