| Abstract | ||
| A pot experiment was carried out to study the effect of treating the Jaafari plant, Tagetes erecta L., with the nano- and aqueous extract of the flowers of the Jaafari plant, prepared using silver nanoparticles and water stress, on some vegetative growth characteristics and the Jaafari plant’s content of some secondary metabolites. A completely randomized block design was used to distribute the treatments. The experiment included Two treatments: treatment with four concentrations of water extract (0, 5, 10 and 15) mg L-1 and three levels of water stress, namely full watering every two, four and six days, based on the gravimetric method, with four replicates for each treatment. Treatment with plant extract at a concentration of 10 mg resulted. L-1 resulted in a significant increase in the rates of plant height, number of leaves, and flower diameter, recorded at 33.33 cm, 11.06 leaves per plant and 7.62 cm, respectively. Treatment with nano extract at a concentration of 10 mg resulted. L-1 significantly increased the carbohydrate and protein content of the leaves and the flowers, as these characteristics gave rates of 27.39% and 10.59%, respectively. The water stress treatment when watering every two days significantly increased plant height, recording 28.58 cm. The same treatment also significantly increased the average flower diameter, recording 6.71 cm. Watering every two days also significantly increased most chemical traits, including the carbohydrate and protein content of the leaves, amounting to 25.80% and 9.38%, respectively. | ||
