摘　　要：为研究不同地区(广东云浮、广西梧州、云南昆明)八角果实中油细胞大小及密度与环境因子(气温、降水量、湿度)的适应关系以及明确广东云浮是否为八角适宜种植区域。以红花八角果实为材料,采用切片显微观察的方法,研究八角果实中油细胞的大小和分布,及其与环境因子的相关性。结果表明,不同区域八角果实不同部位油细胞密度不同,广东和云南八角果实油细胞密度在种仁中表现较为明显,广西八角油细胞密度在种皮中表现突出。油细胞大小从果皮到种仁呈现出明显的变小趋势,广东(32024.075 m^(2)、24834.731 m^(2)、32024.075 m^(2))的油细胞中果皮、种皮和种仁的个体均大于广西(23894.458 m^(2)、15385.529 m^(2)、2532.881 m^(2))和云南(20310.933 m^(2)、4109.318 m^(2)、3250.685 m^(2))。广东云浮和广西梧州地区气候资源相似且均符合八角适宜生长范围,其中油细胞大小与年平均气温、相对湿度和年降水量均呈正相关,油细胞密度与年平均气温、相对湿度和年降水量均呈负相关。不同地区八角油细胞的大小和分布与该地区的环境因子具有相关关系,其中广东云浮地区气候条件、八角果实油细胞大小和密度、及其与该地区的环境因子相关性均表现优越,因此,从气候条件出发,广东云浮地区可列为八角适宜种植区。To study the adaptive relationship between oil cell size and density in star anise fruits fromdifferent regions(Yunfu,Guangdong,Wuzhou,Guangxi,Kunming,Yunnan)and environmental factors(temperature,precipitation,humidity),and to clarify whether Yunfu,Guangdong is a suitable planting area for star anise.Using safflower star anise fruit as the material,the size and distribution of oil cells in star anise fruit were studied by sectioning and microscopic observation,as well as their correlation with environmental factors.The results showed that the oil cell density varied in different parts of the star anise fruit in different regions.The oil cell density of star anise fruits in Guangdong and Yunnan were more pronounced in the kernel,while the oil cell density of star anise fruits in Guangxi was more prominent in the seed coat.The size of oil cells shows a significant"decreasing"trend fromthe peel to the kernel,Guangdong(32024.075 m^(2),24834.731 m^(2),32024.075 m^(2)).The individual numbers of fruit coat,seed coat,and kernel in the oil cells are greater than those in Guangxi(23894.458 m^(2),15385.529 m^(2),2532.881 m^(2))and Yunnan(20310.933 m^(2),4109.318 m^(2),3250.685 m^(2)).The climate resources in Yunfu,Guangdong and Wuzhou,Guangxi are similar and both conform to the suitable growth range of star anise.The size of oil cells is positively correlated with annual average temperature,relative humidity,and annual precipitation,while the density of oil cells is negatively correlated with annual average temperature,relative humidity,and annual precipitation.The size and distribution of star anise oil cells in different regions are correlated with the environmental factors in the region.Among them,the climate conditions,fruit oil cell size and density,and their correlation with the environmental factors in the Yunfu area of Guangdong are superior.Therefore,based on climatic conditions,the Yunfu area in Guangdong can be classified as a suitable planting area for star anise.
