Abstract

Abstract: To determine cold tolerance of the cultivars of‘Shushanggan’apricot，six genetypes of Xinjiang local apricot variety‘Shushanggan’were selected as trial population，seven indicators of flower organs including browning rate，LT50，free proline and MDA contents，SOD，POD and CAT activities were established and investigated under artificial freezing test（0，–2，–4，–6，–8，–10 ℃），the results showed that the cold resistant genetype is S6，which gave a theoretical support for the breeding and production of‘Shushanggan’apricot in Xinjiang.

Key words: apricot, Shushanggan apricot, cold hardiness
