春季萌发受抑早实核桃园土壤盐分分析及其生理响应

Soil Salinity Analysis of Early Bearing Inhibited Walnut Orchard and Its Physiological Responses in Spring

以温宿县早实核桃园为研究区域,通过采集不同土层土壤和枝条叶片进行盐分分析和生理指标的测定。结果表明:温宿县萌发受到抑制核桃园土壤盐分显著高于对照,对抑制核桃树萌发有一定的影响;萌发受到抑制的核桃树体内膜透性增加,丙二醛(MDA)含量和脯氨酸大量积累,通过方差分析达到了差异显著水平,而可溶性糖含量显著降低,叶绿素含量略有下降。

Taking the early bearing walnut orchard in Wensu country as a study case, soil salinity throuth collecting soil samples of different layers was analyzed and some physiological indexes were measured. The results showed that soil salinity of the early bearing inhibited walnut orchard in Wensu was significantly higher titan controlled experiments. It had an influence on inhibiting germination of walnut trees. Membrane permeability was enhanced and the concentration of malondialdehyde as well as proline was significant accumulated by variance analysis. By contrast, soluble sugar was significantly lower than control and chlorophyll content was a little lower than control.
