广西乐业县掌叶木果实表型性状及种子油研究

Phenotypic character and seed oil of fruit of Handeliodendron bodinieri in Leye county,Guangxi province

以广西乐业县掌叶木果实及种子为材料,研究掌叶木果实、种子表型性状及种子、种仁含油率和种子油脂肪酸组成情况。结果表明:广西乐业县掌叶木单球果重3.23 g,单种重0.31 g;单果长31.98 mm、宽14.87 mm;单种长10.47 mm、宽7.17 mm;气干状态下种子含水量13.69%、千粒重170.82 g;出种率13.93%、出仁率64.24%;种子和种仁含油率分别为42.26%、55.93%;种子油含有13种脂肪酸,主要为芥酸35.8%、油酸25.6%、花生一烯酸14.5%、亚油酸8.5%、二十四碳一烯酸(神经酸)8.3%,以不饱和脂肪酸(94.1%)为主,具有重要的开发利用价值。

With the fruit and seed of Handeliodendron bodinieri in Leye county, Guangxi province as materials, the phenotypic characters of Handeliodendron bodinieri fruit and seed, the oil contents of seed and seed kernel and fatty acid composition of seed oil were studied. The results showed that the single fruit weight of Handeliodendron bodinieri grown in Leye country, Guangxi peovince was 3.23 g, and the single seed weight was 0.31 g. The single fruit length and width were 31.98 mm and 14.87 mm respectively, and the single seed length and width were 10.47 mm and 7.17 mm respectively. The water content in seed was 13.69% under the air - dried condition, and the thousand seeds weight was 170.82 g. The seed rate and kernel rate were 13.93% and 64.24% respectively. The oil contents of seed and seed ker- nel were 42.26% and 55.93% respectively. The seed oil contained 13 kinds of fatty acids, including erucie acid 35.8%, oleic acid 25.6%, arachidonie acid 14.5%, linoleie acid 8.5%, and nervonie acid 8.3%, and unsaturated fatty acid （ 94.1% ） was the main composition, which made it have great value of development and utilization.
