摘要: 试验筛选耐盐樱桃品种,旨在为樱桃在天津盐碱地的栽植提供依据。选择蓟县中性土和西青盐碱地为试验地,以Early American(AM)、Brooks(BRO)、Santina(SAN)3个樱桃品种嫁接苗为试材,研究了不同土壤环境条件下樱桃植株叶片的相对膜透性、丙二醛(MDA)、可溶性糖、脯氨酸(PRO)的含量及过氧化物酶(POD)、超氧化物歧化酶(SOD)的活性等的变化。结果表明,盐碱土增加了AM和BRO品种植株叶片的细胞膜透性,分别增加了30.0%和73.3%;AM和SAN的丙二醛含量分别增加了50%和15.6%;SAN的可溶性糖含量降低了27.0%;BRO的脯氨酸含量增加了1.72倍;SAN的POD酶活性增加了1.43倍;AM的脯氨酸含量降低了79.0%;BRO和SAN的SOD酶活性分别增加了3.33倍和1.43倍;AM的SOD酶活性降低了46.6%。隶属函数综合分析显示,3个品种的耐盐性顺序由高到低依次为SAN、BRO、AM,因此,SAN品种适合天津盐碱地栽植。

Abstract: In order to screen sweet cherry cultivars for cultivation in saline-alkaline land of Tianjin, the relative membrane soil conditions of cherry leaf permeability, malondialdehyde(MDA), soluble sugar, proline(PRO)content and peroxidase(POD)activity, superoxide dismutase(SOD)activity were studied with seedlings grafted by 3 cherry varieties named as Early American(AM), Brooks(BRO), Santina(SAN)on 2 kinds of root stock, and the seedlings were planted in neutral soil in Jixian County and saline-alkaline soil in Xiqing District. The results are as follows. In the saline-alkaline soil, the cytoplasmic membrane permeability of AM and BRO increased 30.0% and 73.3%, respectively. The MDA content of AM and SAN increased 50% and 15.6%, respectively. The soluble sugar content of SAN reduced 27.0%. The proline content of BRO increased 1.72 times. The POD enzyme activity of SAN increased 1.43 times. The proline content of AM reduced 79.0%. The SOD enzyme activity of BRO and SAN increased 3.33 times and 1.43 times, respectively. The SOD activity of AM decreased 46.6%. The membership function analyses show that the salt tolerance of 3 varieties, from high to low, is SAN, BRO, AM, therefore, SAN is suitable for planting in the saline-alkaline soil of Tianjin.
