摘要: 为探讨赣州油 1号赣州油 2号赣州油 3号赣州油 4号赣州油 5号油茶Camellia oleifera新品种的经济性状,以这5个8~10年生油茶新品种2011-2013年的调查数据为材料,对其果实主要经济性状及相关性进行了分析和评价。结果表明:赣州油1~5号油茶新品种果实性状指标的差异明显,果形以桃形、球形、橘形 等3种为主,果色主要有红色、黄色和青色,果实越大,果皮越厚,500 g鲜籽个数越少,平均果形指数为1.07;产油量是由含油率及产果量决定,鲜果含油率大小依次为赣州油3号>赣州油2号>赣州油4号>赣州油5号>赣州油1号,666.67 m2产油量分别为赣州油1号>赣州油2号>赣州油3号>赣州油4号>赣州油5号;果实经济性状指标间相关性显著,果径与果皮厚度之间(r = 0.944 3);果形指数与 500 g 鲜果数(r = 0.858 0),鲜果出籽率(r = 0.807 1),干出籽率之间(r = 0.849 7);500 g 鲜果数与 500 g 鲜籽数(r = 0.842 6),干出籽率(r = 0.896 3),鲜果含油率之间(r = 0.837 4);500 g 鲜籽数与干出籽率(r = 0.800 4),种仁含油率(r = 0.804 3),鲜果含油率之间(r = 0.946 4);鲜果出籽率与干出籽率之间(r = 0.892 2);干出籽率与鲜果含油率之间(r = 0.917 8),均存在极显著正相关关系(P<0.01)。果形指数与鲜果含油率之间(r = 0.650 6);500 g鲜果数与鲜果出籽率之间(r =0.684 2);鲜果出籽率与鲜果含油率之间(r = 0.666 0,);种仁含油率与鲜果含油率之间(r = 0.656 4),都存在显著正相关关系(P<0.05)。果高与 500 g 鲜籽数(r =-0.748 4),种仁含油率之间(r = -0.812 4);果径与果形指数(r = -0.746 0),500 g 鲜果数(r = -0.977 0),500 g 鲜籽数(r =-0.932 3),干出籽率(r = -0.863 9),鲜果含油率之间(r = -0.889 4,);果皮厚度与果形指数(r = -0.847 0),500 g 鲜果数(r = -0.958 9),500 g 鲜籽数(r = -0.872 7),鲜果出籽率(r = -0.803 3),干出籽率(r = -0.981 3),鲜果含油率之间(r = -0.934 6),存在极显著负相关关系(P<0.01)。果径与种仁含油率之间(r = -0.663 4)存在显著负相关关系(P<0.05)。表4参18Abstract: To provide a theoretical basis for optimization and rational allocation of seed so as to improve the economic traits for new Camellia cultivars of Ganzhou Oil No. 1-5, 8-10-year-old trees of these five cultivars were studied using research data from 2011 to 2013 as material. A correlation analysis of major economic traits of the fruits was conducted and evaluated. Results showed three main fruit shapes: peach shape, spherical, and orange shape and three main fruit colors: red, yellow, and blue. The larger the fruit was and the thicker the peel was, the less the 500 g fresh seed number. The average fruit shape index was 1.07. The order of fresh fruit oil content was Ganzhou Oil No. 3>No. 2>No. 4>No. 5>No. 1; and the order for oil production of 666.67 m2 was Ganzhou Oil No. 1>No. 2>No. 3> No. 4>No. 5. Fruit economic traits showed significantly positive correlations(P<0.01) for fruit diameter and pericarp thickness (r = 0.944 3), fruit shape index and the number of 500 g fresh fruit (r = 0.858 0), fresh fruit seed rate (r = 0.807 1),dry fruit seed rate (r = 0.849 7), 500 g fresh fruit and 500 g fresh fruit seed (r = 0.842 6), dry seed rate (r = 0.896 3),fresh fruit oil content (r = 0.837 4), 500 g fresh seed number and dry seed rate (r = 0.800 4), kernel oil content rate (r = 0.804 3), fresh fruit oil content (r = 0.946 4, P<0.01), fresh fruit seed rate and dry seed rate (r = 0.892 2), and dry seed rate and fresh fruit oil content (r = 0.917 8). Significant positive correlations(P<0.05) were also noted for fruit shape index and fresh fruit oil content (r = 0.650 6), the number of 500 g fresh fruit and fresh fruit seed rate (r =0.684 2), fresh fruit seed rate and fresh fruit oil content (r = 0.666 0), and seed oil content and fresh fruit oil content (r = 0.656 4). Significant negative correlations(P<0.01) for fruit tree height, 500 g fresh fruit seed number (r = -0.748 4), seed oil content rate (r = -0.812 4), fruit diameter and fruit shape index (r = -0.746 0), 500 g fresh fruit number (r = -0.977 0), 500 g fresh seed number (r = -0.932 3), dry seed rate (r = -0.863 9), fresh fruit oil content rate (r = -0.889 4), pericarp thickness and fruit shape index (r = -0.847 0), 500 g fresh fruit number (r = -0.958 9), 500 g fresh seed number (r = -0.872 7), fresh fruit seed rate (r = -0.803 3), dry seed rate (r = -0.981 3), fresh fruit oil content rate (r = -0.934 6). A significant negative correlation between fruit diameter and the seed kernel oil (r = -0.663 4, P<0.05) was also found.[Ch, 4 tab. 18 ref.]
