Color Characteristics Analysis Of Three Kinds Of Pearl Oyster And The Correlation Between Color And Rowth Traits

Pinctada margaritifera, Pinctada martensii and Pteria penguin is widely distributed in Hainan, the seawater pearl production is very important of the three kinds of shellfish, the three were able to produce different colors of pearls. This study was designed to understand the Hainan Pinctada margaritifera resources by analyzing the diversity and growth traits in three Pinctada margaritifera color and color parameters of the correlation, provide a theoretical basis for further cultivate the color quality of the pearl.The pearl is a pearl sac secretion of nacre deposition formation from pearl oyster mantle made. The artificial pearl, the pearl of a small piece of mantle cell Babe shell nacre color directly affects the color of the pearl (Zhao-mei Meng,1996). The pearl color is one of the main factors determine pearl quality and price, so the color of the shell nacre has become an important goal of the pearl oyster genetics and breeding.Wild or cultured Pinctada margaritifera, Pinctada martensii, penguin Pinctada margaritifera shell as the research object of this paper, CSE-1testing and analysis system to determine the three kinds of shellfish nacre structure of tristimulus values XYZ and color values Lab, and the Lab value indicators, respectively, three types of Pinctada margaritifera shell nacre, cluster analysis, to build the chromaticity diagram, analysis of the correlation of color index and Growth Characters the hope that through such an analysis to determine the color of wild shellfish rich and growth traits and Lab values of the relationship between. On them the mantle of the corresponding shell nacre seven consecutive different sites for farming shellfish (an age of two years) in addition to cluster analysis and Correlation Analysis of, color analysis, expect to get different sites of rooms What differences, which provide the basis for the choice of a small piece of the plug cells.The results show that the wild North Sea, the color of the Pinctada margaritifera is better than the wild population of Sanya, on the growth, shape and color in the wild populations of the North Sea shellfish color better, more conducive to high-quality black pearl. Sanya wild populations in the wild populations of Ma Pui more suitable for small pieces of shellfish, especially in its nurturing Kim.Better for the breeding age and two age Ma Pui, the second age of Ma Pui color in an age of Markov Tony Beckham in the second stage in the growth, shape and color, Ma Pui color better on different bit the point of the color parameters found in the two age Markov Tony Beckham point seven colors better, so as to select the reference of the small piece of the plug cells.Pteria penguin as an age of shellfish can not be achieved, we analyzed only the second instar Pteria penguin in the analysis of different sites found that sites in four colors best suitable chosen as the nucleus inserted small pieces of cells.
