【摘要】 以6个樟子松不同种源幼苗为供试材料,采用室内盆栽法,对其耐盐性进行评价。结果表明,在土壤盐胁迫下,不同种源幼苗苗高、地径、生物量均受到了抑制,根冠比随着盐处理浓度的增大而增大。6个樟子松种源耐盐性存在差异,其排序为:柳河>加格达奇>呼玛>鄂温克旗>榆林>桦南。柳河种源能耐8 g/kg盐胁迫,其他种源只能耐5 g/kg盐胁迫。更多还原

【Abstract】 Using the pot experiment,the seeds of 6 Pinus sylvestris var. ongolica. provenances were collected, were observed with 0、3 、5 、8 、10 g/kgof salt NaCl treatments.The result showed that the seedling height, ground diameter, biomass of all the provenance were inhibited under the salt treatments.The root-cap ratio decreased with increasing salt concentration.The salt tolerance of the 6 Pinus sylvestris var. ongolica provenances is in the order of Liuhe>Jiagedaqi>Huma>Ewenkeqi>Yulin>Huanan更多还原
