| Abstract: |
| The experimental materials are four kinds of wild jujube seedlings originated from Shaanxi, Shanxi, Hebei and Liaoning provinces, nutrient solution culture test matrix. The results showed that: 0.3%, 0.6% and 0.9% salt alkaline stress reduced wild jujube height, stem diameter and biomass, With the increase of stress concentrations, the inhibition was more obvious, the plant height and stem diameter of Shaanxi wild jujube were the lowest under 0.9% stress, with 48.55 mm and 4.10 mm, compared with the CK respectively. The total biomass of Shanxi jujube decreased the most, and reduced the 27.79 g·plant-1; except the soluble sugar content in wild jujube leaf stress, 10～50 d decreased 70～110 d rise. At 0.9% concentration, stress for 110 d, MDA content of Liaoning wild jujube leaves, Soluble protein content of Shaanxi wild jujube leaves and proline content of Hebei wild jujube leaves were maximum with 20.81 mmol·g-1, 93.53 mg·g-1, 670.92 μg·g-1 respectively. Comprehensive evaluation; Using subordinate function of four kinds of source regions wild jujube comprehensive evaluation results concluded that a variety of sources wild jujube salinity from strong to weak are: Hebei＞Liaoning＞Shanxi＞Shaanxi. |
