| 摘 要： | 在海南省陵水黎族自治县黎安港选择1.5龄企鹅珍珠贝插核培育游离海水珍珠,20个月后收获优质游离珍珠43颗。全部43颗珍珠的聚类分析结果显示,它们共聚为3个类群,类群彼此间珍珠的直径、珠层厚度、重量以及与金珠的色差均存在显著差异;第1类和第2类群珍珠的明度L值、黄蓝特征b值以及与白珠的色差相似,而且均与第3类珍珠之间存在显著差异;第1类和第3类珍珠的红绿特征a值相似,而且均与第2类珍珠之间存在显著差异。相关分析结果显示,珍珠颜色的L值与珍珠的直径、珍珠质层厚度以及珍珠的重量之间均存在极显著的负相关关系,相关系数分别为-0.567、-0.617和-0.523;a值和b值均与珍珠的直径、珍珠质层厚度以及珍珠的重量之间没有显著的相关性。珍珠的直径、珍珠质层厚度、珍珠的重量与白珠色差以及金珠色差之间都有极显著的正相关关系。

| Abstract: | The 1.5-year-old pearl rine pearls. After 20-month culturing, oysters, Pteria penguin, were used to produce free ma 43 high-quality pearls were harvested and then analyzed. These pearls were clustered into three groups which differed significantly in several characters, including pearl diameter, nacre thickness, pearl weight and color difference from standard golden pearls. Pearls in Group I and GroupII were similar with each other in either of L val- ue, b value or color difference from standard white pearls, and they both were significantly dif- ferent from pearls in Group III. Besides, a value was same for pearls in Group I and Group III, and it was significantly different from that of Group II . Correlation analysis showed that L val- ue of pearl color had significantly negative correlation with pearl diameter, nacre thickness, andpearl weight, with correlation coefficient of -0. 567,-0. 617 and 0. 523 respectively. Nei ther a value nor b value had significant correlation with pearl diameter, nacre thickness, or pearl weight. Moreover, there were also significantly positive correlations between pearl diameter, nacre thickness, or pearl weight and color distances from standard white or golden pearls. |
