不同海区养殖的马氏珠母贝珍珠质颜色比较

Comparison of nacre color of Pinctada martensii cultured in different marine areas

为探讨不同环境对珍珠质颜色的影响,本研究将遗传背景相同的马氏珠母贝分布于海南黎安、广东流沙、广西北海和广西防城4个不同的海区养殖。一年后,用CSE-1型成像色度仪测量4个区域贝壳珍珠质的颜色,记录相应的颜色参数Lab值。结果显示,不同海域养殖的贝壳珍珠质颜色显示了不同的特征,其中广西北海、广西防城和海南黎安这3组贝壳珍珠质颜色较为接近,均表现为明度高、偏黄绿;而广东流沙与这3个地区的色差较大,表现为明度低、黄绿杂色浅、偏白色的特征。

In order to explore the effect of environment on the nacre color of shells, we cultured a group of genetically identical oyster Pinctada martensii in four different areas： Li＇an in Hainan Province, Liusha in Guangdong Province, Beihai and Fangeheng in Guangxi Province. One year later, the shell colors of P. rnartensii in the four areas were measured using CSE-1 Imaging and Color-Measuring System, and the Lab values were recorded. The results showed that the oysters cultured in different areas exhibited different shell colors. Specifically, the oysters of Beihai, Fangcheng and Li＇an were quite close in shell colors, having higher lightness and green and yellow tone, while the oysters of Liusha showed significant color difference in shells to those of the other three areas, demonstrating relatively lower lightness and green and yellow tone, quite close to white color.
