Abstract:
Agricultural nanoparticles provide inspiring opportunities to better crop yieldsand stress resistance. Wheat (Triticum aestivum L.) is a globally important foodcrop with rising which requires expanding agricultural production area in a moresustainable manner. This study examined the biosynthesis of coppernanoparticles (CuNPs) using Bombax ceiba L. leaves extract. The researchersused UV-Vis spectroscopy, FTIR, SEM, and XRD to characterize the CuNPsand verified their functional groups, morphology, and purity. A preliminary studywas performed in vitro using six concentrations (5,10,15,20,40 and 60ppm) ofCuNPs on the Akbar-19 wheat variety and then germination percentage andgrowth parameters (length of root and shoot, fresh and dry weight of root andshoot) was recorded after 7 days. Based on the data from this trial, the idealconcentrations were identified using two concentrations (20 and 40 ppm). Thestudy also treated five wheat varieties (Akbar-19, Barlaug-16, Wafaq-23, Pak-13,and NARC-Super) to identify which would work best when exposed to CuNPs.Varieties namely Wafaq-23, and Barlaug-16 were chosen as representatives ofthe best performing varieties in the in-vitro study and were employed for the potexperiment including irrigation treatments representing three differentconditions; normal (irrigation with water), drought (no irrigation), and saline(irrigation with 150mM NaCl solution) for 21 days . The priority growthattributes evaluated associated to these treatments were a combination of keyphysiological and morphological traits. The results showed significant variabilityand enhancement in growth parameters in Wafaq-23 under saline (irrigationwith 150mM NaCl solution) and drought stress conditions. However, Barlaug-16 was adaptive to drought and saline’s stress under low CuNPs concentration(20ppm). This finding has important agricultural applications for greensynthesized CuNPs, suggesting different dose and condition responses and thepossibility of genotypic differences in wheat varieties.
