ABSTRACT The reduction of the plant performance was observed in plant growth and yield with reduction in the plant’s production of at least 20% of irrigated land worldwide due to the salinity, so it is the major abiotic stresses. For promoting growth and increasing crop yield natural extracts were used in agriculture and horticulture as bio-stimulants. At the Experimental Farm of the Faculty of Agriculture Zagazig University, a pot experiment has been done under greenhouse condition for studying the spray of natural extracts; moringa leaves extract (MLE); algae extract (AE); licorice root extract (LRE) and propolis extract (PE) on yield, photosynthetic pigments and nutrient uptake of wheat grown on saline soil taken from Abou Hammad county, El-Sharkia Governorate, Egypt. Results showed that spraying with different organic extracts significantly increased yield, protein content, photosynthetic pigments and nutrient uptake as compared to untreated plants. Spraying with MLE gave an increase of all parameters i.e., yield, protein content, NPK, Fe, Zn, and Mn accumulation of wheat plants. The highest increases in grain yield were 81%, 110%, 78% and 50%, caused by MLE, AE, LRE and PE, respectively.

应用有机提取物减轻盐分胁迫对小麦生长、产量和养分吸收的影响

摘要 在植物生长和产量方面观察到植物性能的降低，由于盐分导致全球至少 20% 的灌溉土地的植物产量减少，因此它是主要的非生物胁迫。为了促进生长和增加作物产量，天然提取物在农业和园艺中用作生物刺激剂。在扎加齐格大学农学院实验农场，在温室条件下进行了盆栽实验，研究喷洒天然提取物；辣木叶提取物（MLE）；藻类提取物（AE）；甘草根提取物 (LRE) 和蜂胶提取物 (PE) 对采自埃及 El-Sharkia 省阿布哈马德县的盐渍土壤上生长的小麦的产量、光合色素和养分吸收的影响。结果表明，与未经处理的植物相比，喷洒不同的有机提取物可显着提高产量、蛋白质含量、光合色素和养分吸收。喷洒 MLE 增加了所有参数，即小麦植株的产量、蛋白质含量、NPK、Fe、Zn 和 Mn 积累。谷物产量的最大增幅分别为 81%、110%、78% 和 50%，分别由 MLE、AE、LRE 和 PE 引起。
