项目摘要

In this study, the effects of light with different wave length on anthocyanin synthesis of grape berries were determined. In comparison among cultivars, the anthocyanin synthesis of berry section was markedly suppressed in all cultivars. This suggested that anthocyanin synthesis of grape berry was stimulated by existance of light. And the effect of the quality of light was also cralifed. Genelally, white and ultraviolet rays individually, enhanced anthocyanin synthesis and concomitant irradiation of both rays was more effective.In the experiment for interaction of white and ultraviolet rays on 'Gros colman' grapes, although UV-B seemed to be more effective than UV-A for anthocyanin synthesis, it was suppressive at higher intensity. Among the visible rays, light of blue and red regions were more effective than green and yellow lights. Considering the response to ultraviolet rays, it was found that 'Gros colman' berries had the maxima of response to light in the region from blue to ultra violet of linger wavelength and red for anthocyanin synthesis. And the constitution of anthocyanin pigments as well as the total amount was also considerably affected by lighting condition.Further, it was shown that the levels of sugar and abscisic acid markedly affected the anthocyanin synthesis of berry section, and they altered the dependency of anthocynin snthesis of berry section to light. And also, the close corelation was found between anthocyanin synthesis and phenyl alanineammonia-lyase activity. This suggested the effect of light irradiaion on anthocyanin synthesis was mediated by its effect on PAL activity.

研究了不同波长的光照对葡萄果实花色苷合成的影响。在品种间比较中，所有品种浆果切片的花青苷合成均受到显著抑制。这说明光的存在促进了葡萄果实花色苷的合成。并对光质的影响进行了验证。白色光和紫外光单独照射能促进花青苷的合成，两者联合照射效果更好，在白色光和紫外光交互作用的实验中，UV-B对花青苷合成的促进作用似乎比UV-A更强，但在较高强度下，UV-B对花青苷合成的抑制作用更强。在可见光中，蓝色和红色区域的光比绿色和黄色光更有效。从对紫外线的响应来看，'Gros colman'浆果在蓝光-长波紫外线和红光范围内对花青素合成的响应最大。光照条件对花青苷色素的组成和总量也有显著影响，糖和脱落酸水平显著影响果实切片花青苷的合成，改变了果实切片花青苷合成对光照的依赖性。花青苷的合成与苯丙氨酸解氨酶活性密切相关。这说明光照对花青苷合成的影响是通过对PAL活性的影响来实现的。
