Taken together, these results indicate that cosuppression of the tobacco chs gene can occur using the equivalent Petunia gene, and demonstrate a linkage between the expression level of chs mRNA, cyanidin content, and flower color in transgenic tobacco plants.

综合而言，本研究提供了广泛的实验证据，说明菸草chs基因的共同抑制作用是可以透过别种植物如矮牵牛的相似基因而发挥作用，导致转殖菸草产生白色花朶；并清楚显示chs mRNA表现量、花青素含量及转殖菸草花朶颜色的关联性。

The correlations of eleven floral and fruit quantitative traits of Liriodendron interspecific hybrids(L. chinense×L. tulipifera) and its parent species were analysized.The aglycone and glycoside of flavonoid and carotinoids of perianth segment in the three groups were studied qualitatively and quantatively by high performance liquid chromatography.The results were as followed: The aglycone such as cyanidin, 6-hydroxyflavone and trans-chalcone and the glycoside such as glucose, rhamnose and galactose were discovered in Liriodendron interspecific hybrids and Liriodendron chinense,carotinoids such as lycopene and β-carotene were also discovered.

本文对鹅掌楸、北美鹅掌楸和杂交F_1的花果共11 个数量性状进行分析，并应用高效液相色谱对上述三大类群花被片类黄酮糖苷配基和结合糖及类胡萝卜素进行了定性和定量研究，结果如下：鹅掌楸和杂交鹅掌楸花被片类黄酮糖苷配基为花青素、6-羟基黄酮和反式查尔酮，糖苷配基结合糖为葡萄糖、鼠李糖和半乳糖；类胡萝卜素为β-胡萝卜素和番茄红素。

Results were as follows: Excluding white fowers, there were four anthocyanins in petals of crape myrtle, whichwere delphinidin 3-O-glucoside (Dp3G), cyanidin 3-O-glucoside (Cy3G), petunidin3-O-glucoside (Pt3G) and malvidin 3-O-glucoside (Mv3G).

研究结果表明：除白色紫薇外，紫薇的花瓣中主要含有四种花青素苷，分别是飞燕草素-3-O-葡萄糖苷(Dp3G)，矢车菊素-3-O-葡萄糖苷(Cy3G)，矮牵牛素-3-O-葡萄糖苷(Pt3G)和锦葵素-3-O-葡萄糖苷(Mv3G)。

It is ascertained that the fine formation of cyanidine dependslargely on direct natural lighting.

试验结果提出花青素形成对直射自然光有明显的依赖性。

By field test and artificial coloring in vitro,it is for the first time affirmedthat cyanidine synthesis in rind in vitro is inhibited markedly when temperatures arebelow 13℃ or over 32℃.

通过田间试验和离体人工着色方法证实，在果实离体条件下，红富士苹果果皮花青素合成的适宜温度为20℃～25℃。

Red light (640nm)accelerated cyanidine synthesis in rind and resulted in increase of the total amount.Treatments of continuous red,blue or ultraviolet lights inhibited cyanidineformation.

果实着色期红光(640nm)照射4～7天后，在直射自然光照射的环境下，可加速果皮花青素合成并使积累总量增加。
