对元宝枫翅果油脂含量和累积规律进行了研究。结果表明：杨陵地区１０月底元宝枫翅果出仁率为３５．９１％（２３．３０％～４４．３０％），种仁含油率为４８．００％（４０．９０％～５２．５１％），翅果含油率为１７．２３％（９．８８％～２２．２６％）。根据翅果生长及含油量变化，将翅果中油脂累积过程分为４个阶段：种仁形态形成期、油脂缓慢形成期、油脂快速增长期和油脂减缓增长期。杨陵地区翅果油脂形成的快速期在８月下旬至１０月上旬末，油脂最大产量出现在１０月底。元宝枫个体株间油脂积累量差异显著，应尽早进行优树选择
The oil content and accumulation law of Aloe arborescens were studied. The results showed that the germination percentage of Maple fruit in the Yangling area was 35.91% (23.30% ~ 44.30%), the seed oil content was 48.00% (40.90% -52.51% ), Samara oil content was 17.23% (9.88% ~ 22.26%). According to the growth and oil content of samara, the process of oil accumulation in samara is divided into four stages: the formation of seed, the slow formation of oil, the rapid growth of oil and the slow growth of oil. Yangling region fin oil formation of the rapid period in late August to early October late, the maximum output of fat appeared in the end of October. There was significant difference in the accumulation of oil between individual strains of Alopecurus asiatica, which should be selected as soon as possible
