摘　　要：该研究分别以蓝紫、红、黄色系月季品种‘微蓝’、‘梅朗口红’和‘朝圣者’为材料,将其置于正常光照(CK)、遮光25%(S_(Ⅰ))和遮光50%(S_(Ⅱ))条件下培养,测量花瓣6个发育阶段的CIE值、pH值以及总类黄酮、总花青苷含量,并分析了各品种不同遮荫处理下测定参数间的相关性,探讨遮荫对不同色系月季发育过程中花色变化的影响。结果表明:(1)遮荫处理会导致‘微蓝’花瓣着色变浅、亮度增加,S_(Ⅱ)处理下花瓣的蓝度积累最多,适当遮荫以利于其花瓣显蓝;‘朝圣者’在S_(Ⅰ)处理下花瓣颜色稳定,且色度积累与CK相似,S_(Ⅱ)条件下花瓣颜色波动较大,但在盛花期饱和度最高;S_(Ⅰ)处理下对‘梅朗口红’花瓣颜色影响较小,S_(Ⅱ)处理下花瓣红度减少、黄度增加,且色彩波动较大,大量遮荫会导致‘梅朗口红’花瓣红色变浅、花瓣泛黄。(2)遮荫可以通过影响‘微蓝’花瓣pH值,进而影响其花色苷稳定性,最后在花色苷和pH的协调作用下,使其花瓣显蓝紫色;适当遮荫提高了‘梅朗口红’花瓣pH与色彩间的相关性,同时花青苷积累量减少、类黄酮增多,导致花瓣红色变浅、泛黄;遮荫会引起‘朝圣者’花瓣pH与类黄酮的协同作用,进而使其黄色和彩度加深。研究发现,遮荫对不同色系月季发育过程中花色变化的影响存在显著差异,遮荫50%提高了蓝紫色和黄色品种月季的观赏性,但降低了红色月季的观赏性;遮荫25%对3个品种月季观赏性的影响较小。In order to explore the influence of shade on the color changes of different color Chinese rose(Rosa chinensis Jacq.)during their development,we took red variety‘Rouge Meilland’,yellow variety‘The Pilgrim’,and blue purple variety‘Kinda Blue’as experimental materials.Under the condition of normal light(CK),25%shading(S_(Ⅰ))and 50%shading(S_(Ⅱ)),we measured petals 6 stages of CIE value,total flavonoids and total cyanine glycosides,pH value,and the correlation between the measured parameters of various varieties.The study found that:(1)shading treatment can lead to lighter coloring and increased brightness of the petals of‘Kinda Blue’,and the accumulation of blueness was the largest under S_(Ⅱ)treatment,so appropriate shading can facilitate its blueness.Under S_(Ⅰ)treatment,‘The Pilgrim’petal color was stable,and the chroma accumulation was similar to CK.Under S_(Ⅱ)condition,the petal color fluctuated greatly,but the saturation degree was the highest at the full flowering stage.Treatment S_(Ⅰ)has little influence on the petal color of‘Rouge Meilland’,while treatment S_(Ⅱ)has less redness and more yellowness,and the color fluctuation was large.A large amount of shade will lead to lighter red and yellow petals of‘Rouge Meilland’.(2)Shade could affect the stability of anthocyanin by affecting the pH value of the‘Kinda Blue’petals,and finally,under the coordinated action of anthocyanin and pH,it made the petals blue and purple.Proper shade increased the correlation between pH and color of the petals of‘Rouge Meilland’,while the accumulation of anthocyanin decreased and flavonoid increased,leading to light red and yellow of the petals.Shade could cause a synergistic effect between pH and flavonoids of‘The Pilgrim’petals,thus enhancing their yellow and chromatism.There were significant differences in the influence of shading on the color changes of different color Chinese rose during the development process.Shading 50%increased the ornamental ability of blue and yellow
