| Research Abstract |
Effects of shading on the expression of MdTFL1 and MdFT1 genes and the rate of flower bud formation were investigated. In shading treatment, the expression of MdTFL1 was higher than that in non-shading treatment throughout the measuring dates. The shading treatment significantly decreased the flower bud formation rate. We examined the effects of the irradiation of light-emitting diode (LED) of blue or red at night on abscisic acid (ABA) metabolism and anthocyanin formation in grapes. These results suggest that red LED application at night influences endogenous ABA concentrations but does not coincide with anthocyanin formation, and blue LED influences gene expression related to anthocyanin formation, but it does not influence endogenous ABA significantly.
