摘　　要：以3个品系的野生玫瑰果为试材,分析果实性状、色泽属性和质构特性,探索果实外观特性及其变化趋势,为野生玫瑰果实的开发利用提供依据。试验结果表明,单果重的变化分为迅速增长期和缓慢增长期,且3个品系均表现出波动变化趋势;3个品系可食率均高于75%;A、B品系果型指数0.6~0.8(呈扁球形),C品系果型指数大于1(为长球状)。3个品系果实性状存在很大差异,体现出果实性状的多样性。随着果实成熟,其亮度逐渐降低,红色度增高,黄色度波动变化;成熟期B品系红色度最高(30.3~39.8),A和B品系的亮度、红色度和黄色度比C品系稳定,具有较高的观赏价值。3个品系果实硬度整体呈下降趋势,成熟期硬度很低,不耐常温贮藏,适合加工果酱类产品。Taking three strains of wild Rose rugose Thunb,namely,A,B and C as materials,the study measures and analyses the fruit characters,color attribute and textural parameter to explore the appearance characteristics and the changing tendency provides theoretical basis for the later development and utilization of wild Rose rugose Thunb. The results show that the change of single fruit weight is divided into rapid growth period and slow growth period,and all three lines show fluctuation trend and the edible rate of three strains is higher than 75%.The fruit type index of A and B was 0.6~0.8（oblate spheroid）,and the fruit type index of C strain was more than1（long sphere）. The fruit characters of the three strains were different,which showed the diversity of fruit characters. As the fruit ripening,its brightness gradually decreased,the red degree increased and the Yellow degree fluctuated,and the red degree of B strain at maturity was the highest（30.3~39.8）. The brightness,red degree and yellow degree of A and B lines were more stable than those of C,and had higher ornamental value.The firmness of the three strains decreased as a whole,and the hardness was very low at maturity. They were not able to withstand normal temperature storage,and were suitable for processing jam products. What＇s more,the hardness of these three strains has overall downward trend. In the mature period,the hardness is extremely low,which describes that it＇s intolerant at room temperature and suitable for jam products.
