The Effect of Spraying with Jasmonic Acid and Sugar Alcohols on some Chemical and Hormonal Properties of Lemon and Benzher Seedlings

Abstract

Abstract In 2022, researchers from the University of Samarra’s Department of Horticulture and the College of Agriculture built a wooden canopy to perform their experiment. To study the effect of spraying with jasmonic acid and sugar alcohols on some chemical and hormonal properties of lemon and benzher seedlings, the seedlings were chosen as homogeneous as possible in size at the age of one and a half years. The experiment included three factors: the first being two Speciess of citrus seedlings, lemon and benzher. The second factor is spraying with three levels of jasmonic acid 0, 10, 20 mmol L-1, and the third factor is spraying seedlings with three concentrations of sugar alcohols 0, 3, 6 ml L-1. The experiment was designed according to a randomized complete block design (RCBD), the results showed the superiority of lime over benzher in the leaves content of nitrogen, chlorophyll, and jasmonic leaves content, and the values were 2.332%, 12.12 mg gm-1, 64.78 mg kg-1, respectively. As for benzher, it excelled in the rate of increase in the percentage of phosphorus, potassium, Carbohydrates, as it recorded 0.476%, 1.240%, and 3.284%, respectively.Also spraying with jasmonic resulted in a significant increase, especially the treatment Ja2, which was superior to the two treatments Ja1 and Ja0 in the leaves content of nitrogen, chlorophyll, leaf content of jasmonic, percentage of phosphorus, potassium, carbohydrates, and the results were 2.364%, 12.34 mg gm-1, 69.13 mg kg -1, 0496%, 1.263%, 3.300%, respectively. Spraying with sugar alcohols had a significant effect at the concentration of 6 ml L-1 S2 in the leaf content of nitrogen, chlorophyll, phosphorus, potassium, and carbohydrates, and the values were 2.339%, 12.20 mg gm-1., 0.491, 1.243%, 3.277%, respectively, while the average of these characteristics was lowest in the control group that received treatment S0. All of the qualities analyzed displayed substantial variations in the binary and triple interactions of the research components.
