Cold resistance in Dendrocalamopsis oldhami from four different geographical provenances

    Corresponding author: FANG Wei

Abstract: To determine cold resistance of Dendrocalamopsis oldhami from four different geographical provenances (Wenzhou,Fu’an,Youxi,and Zhangzhou),changes in semilethal temperature(LT50);peroxidase (POD) activities,malondialdehyde (MDA),proline and soluble protein content over the course of a winter were compared. Results showed that from the four different geographical provenances the semilethal temperature of Dendrocalamopsis oldhami decreased with the drop in temperature,and decreased to -5.1 to -8.1 °C in January. Over the winter,POD,MDA,and proline content increased with the drop in temperature,but the ranges differed for different geographical provenances. The correlation analysis showed significant,negative correlations between solub1e protein in and POD(P<0.01),MDA(P<0.01),and proline (P<0.01);between POD and proline(P<0.01);and between latitude and LT50(P<0.05) and MDA(P<0.05). However,there was a highly significant,positive correlation between POD and proline (P<0.01),LT50 and soluble protein(P<0.01). Principal component analysis indicated that cold-resistance of Wenzhou provenance was best,followed by Fu’an,Youxi,and Zhangzhou provenances.[Ch,7 fig. 6 tab. 16 ref.]
