Comparison on Cold Resistance of Different Ziziphus jujuba var.spinosa(Bunge) Hu Seedlings
摘要
Abstract
One-year Ziziphus jujuba var. spinosa ( Bunge) Hu seedlings from four provenances with different plant types and different tree ages were used to study the effects of natural cooling in winter and different low-temperature treatment on the dormant branchs's physiological and biochemical indicators,proline,soluble sugar,malondialdehyde(MDA) and soluble protein contents. The results showed that higher-level proline, soluble sugar, soluble protein in Ziziphus jujuba var. spinosa (Bunge) Hu favoured cold hardiness, with MDA being the opposite. The seedlings from Xingtai, Hebei province had the most cold hardiness,following by Taiyuan of Shanxi, Weinan of Shanxi and Chaoyang of Liaoning. Vertical branches bending seedlings had the strongest cold hardiness; tufted seedlings were the worst ones. Two-year Ziziphus jujuba var. spinosa (Bunge) Hu seedlings were more stronger than the 1-year ones based on a comprehensive analysis. Proline,soluble sugar, MDA and soluble protein content can be used as key measure indicators of Ziziphus jujuba var. spinosa(Bunge)Hu cold resistance.关键词
