内蒙古不同种源文冠果果实特征及种子含油率调查研究

Investigations on Fruit Character and Seed Oil Content of Xanthoceras sorbifolia from Different Provenances in Inner Mongolia

对内蒙古通辽市、巴彦淖尔市、包头市分布的4个种源的文冠果进行了果实特征和种子含油率的调查研究,结果表明:包头种源的文冠果种仁含油率最高,为63.4%,但平均结果量、种子千粒重、平均每果粒数、平均每株种子总重量和出籽率等果实特征表现最差,分别为2个/株、815.5 g/千粒、13.52粒/果、27.64 g/株、47.85%;通辽种源的种仁含油率同样达到了60%以上,平均结果量、种子千粒重、平均每果粒数、平均每株种子总重量和出籽率等果实特征也表现较优,分别为7个/株、892.5 g/千粒、16.85粒/果、157.70 g/株、51.03%。

Through investigating the fruit characters and seed oil contents of xanthoceras sorbifolia of four prove- nances from Tongliao, Bayannaoer and Baotou in Inner Mongolia, the results show： the kernel oil content of Xan- thoceras sorbifolia in Baotou is the highest, reached to 63.4%, but the average quantity of fruits, thousand - seed weight, average number of seeds per fruit, average total weight of seeds per plant and seed - producing percentage are the lowest, respectively only 2 per strain,815.5 g per thousand - seed, 13.52 per result,27.64 g per plant and 47. 85 %. However, the kernel oil content of Tongliao provenance is also more than 60% , and their fruit characters are also showed relatively good, respectively 7 per strain, 892. 5 g per thousand -seed, 16. 85 per result, 157.70 g per plant and 51.03 %.
