| 英文摘要 | Calcium alginate (caalg) submicroparticles have a potential application in agricultural delivery systems. this study investigated the effects of caalg submicroparticles on seed germination and seedling growth of wheat. caalg submicroparticles with a z-average diameter of around 250.4 nm and a measured zeta potential value of about -25.4 mv were prepared and characterized by dynamic light scattering (dls), scanning electron microscopy (sem) and energy dispersive x-ray spectrometer (eds). after this, the effects of the concentration of caalg submicroparticles (10-500 mu g/ml) on germination percentage, seedling length, the number of adventitious roots, chlorophyll content and soluble protein content were evaluated. the results demonstrated a significant increase in the level of germination percentage (9.0%), seedling index (50.3%), adventitious roots (27.5%), seedling length (17.0%), chlorophyll (8.7%) and soluble protein contents (4.5%) at a concentration of 100 mu g/ml. however, an inhibitory effect was observed at a concentration of 500 mu g/ml. the sem examination showed that caalg submicroparticles could be successfully adsorbed onto the surface of the wheat seed. further studies proved that caalg submicroparticles at a concentration of 100 mu g/ml promoted the expression of indole-3-acetic acid (iaa)-related genes (yucca9, aux1, arf and ugt) in wheat, which resulted in an increase of 69% and 21% in iaa concentration in wheat roots and shoots, respectively. |
