Physiological active substances and fruit affected by light quality

研究了遮荫对MdTFL1和MdFT1基因表达及成花率的影响。在整个测定期间，遮荫处理的MdTFL1表达量均高于非遮荫处理。遮荫处理显著降低了花芽形成率。研究了夜间蓝光和红光LED灯照射对葡萄叶片脱落酸（阿坝）代谢和花青素形成的影响。这些结果表明，红色LED应用在夜间影响内源阿坝的浓度，但不符合花青素形成，蓝色LED影响花青素形成相关基因的表达，但它不影响内源阿坝显着。

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.
