Abstract

The nature of the soil is a very important factor in the growth and development of a crop. Crop plants suffer a decline in growth and yield, when exposed to the saline condition. Pea considers one of the main leguminous crops, due to its ability to produce significant quantities of protein, carbohydrates and nutrient-rich seeds. Plants were subjected to four salt treatments, 4, 8, 12 and 16 mmhos cm-1 of sodium chloride and sodium sulfate and the biomass and biochemical responses were measured. All growth attributes such as stem, root and leaf fresh and dry weight decrease with the increased salinities doses. Salt treatments were no significant effects on the biomass and quantitative changes in starch, protein and soluble sugar in seeds of pea. But it was noted that the starch contents were much reduced in 16 mmhos cm-1, the salinity level of sodium chloride and sodium sulfate as compared to control. The protein content and sugar content value were increased in a higher concentration of sodium chloride and sodium sulfate, when compared to control in Pea, CV. Azad P-1. The proline content increased with salt stress up to 8 mmhos cm-1 in CV-Azad P-1. It was also observed that the high dose of sodium sulfate is declined biomass and quantitative changes in starch, than that of sodium chloride solution in pea seeds.
氯化钠和硫酸钠对豌豆种子生物量及淀粉、蛋白质和总可溶性糖含量变化的影响
土壤的性质对作物的生长发育是一个非常重要的因素。农作物暴露在盐水环境中,生长和产量都会下降。豌豆被认为是主要的豆科作物之一,因为它能够产生大量的蛋白质、碳水化合物和营养丰富的种子。以4、8、12和16 mmhos cm-1氯化钠和硫酸钠为盐处理,测定其生物量和生化反应。随着盐分剂量的增加,茎、根、叶的鲜重和干重等所有生长性状均下降。盐处理对豌豆种子中淀粉、蛋白质和可溶性糖的生物量和数量变化无显著影响。但在16 mmhos cm-1、氯化钠和硫酸钠的盐度水平下,淀粉含量明显低于对照。在较高浓度的氯化钠和硫酸钠处理下,豌豆的蛋白质含量和糖含量均高于对照。Azad p - 1。CV-Azad P-1脯氨酸含量随着盐胁迫的增加而增加,最高可达8 mmhos cm-1。高剂量的硫酸钠溶液比氯化钠溶液对豌豆种子生物量和淀粉含量的影响更大。
