摘　　要：[目的]探究不同栽培密度下骏枣果实色度的差异,为新疆红枣产业的发展提供选择依据和指导信息。[方法]以3～5年生不同栽培密度(1100、592和317株/667m^2)的骏枣为研究对象,采用X-rite色差计可以快速、准确获得果实的色品坐标系(L、a、b)。通过新复极差法分析各栽培密度之间果实色度的差异。[结果]栽培密度为592株/667 m^2的骏枣试验地果实色度较其他两个栽培密度(317、1100株/667 m^2)显著,尤其是果实亮度(L)和果实饱和度(C)。[结论]充足的光照更有利于提高红枣果实的色度品质,主要是果实的红色程度得到提高。[Objective]The aim of this research was to explore the discrepancy in Jun -jujube fruit chroma under different planting densities to provide the basis for selection and guidance information for the development of jujube industry in Xinjiang.[Method]The 3 - 5 year old Jun - jujube under different planting densities were taken as the experimental materials.The fruit chromaticity coordinate system was acquired quickly and accurately via the X - rite colorimeter.In order to analyze the fruit chromaticity differences between planting densities,the SSR was used.[Result]The Jun -jujube under the density of 592 plants/667 m2 gained the better fruit chroma than the other two culture densities(317,1 100 plants/667 m^2 ),especially in terms of fruit brightness(L) and fruit saturation(C).[Conclusion]Adequate sunshine is more conducive to improve the quality of jujube fruit chroma,and the redness degree of fruit was mainly enhanced.
