Fundamental Study on Instructional Materials of Kenaf useful for Environment Preservation

1)在福冈栽培了青皮3号、浙江1号和大沼泽地41号3个红麻品种，并进行了观察。得到以下结果：种子的发芽率取决于种子的种类，它们可以在福冈种植。红麻茎高、茎粗、茎重及侧根数排序为：Everglades 41 bb0，浙江1 bb1，青皮3号。开花和成熟时间顺序为青皮3号bb0浙江1号bb1沼泽地41号。红麻叶型明显（青皮3号和浙江1号为棕榈型，大沼泽41号为全叶型）。2)韧皮纤维中灰分、热水浸出物、碱浸出物和孔纤维素的含量大于芯纤维。红麻叶的营养成分与木犀叶相似。3)红麻花瓣中的色素（红色和黄色）可用作酸碱指示剂和染料。4)红麻吸附剂对废食用油及废水中污染物（染料、金属离子）的吸附量大于棉、木浆和活性炭。5)红麻的含水率高于木浆和棉花，其原因之一是红麻纤维的半纤维素含量高于木浆和棉花。6)对3个红麻品种（4个品目）种子油的脂质成分进行了测定。各品种间性状差异不显著。脂肪含量约为20%，为半干性油。脂肪酸。甾醇和生育酚的组成与棉籽油相似。因此，由于脂肪含量相对较高，因此可以将其用作食用油。

1) Three varieties of kenaf (Qingpi No 3, Zhejiang No.1 and Everglades 41) were cultivated in Fukuoka and ovserved. The following results were obtained ; the percent germination depended on the kinds of the seeds and they could be cultivated in Fukuoka. The order of thehight, the diameter and the weight of kenaf stem and the number of lateral roots was Everglades 41> Zhejiang No.1> Qingpi No 3. The order of the time of flowering and maturity was Qingpi No 3> Zhejiang No.1 > Everglades 41. Kenaf has distinct leaf shapes (Qingpi No 3 and Zhejiang No.1 : palmatified type and Everglades 41 : entire-leaf type).2) The content of ash, hot water extract, alkali extract and holecellulose in bast fibers was greater than the content of those in core fibers. and the nutritive substances of kenaf leaves were analogous to those of mulukhiyya.3) Pigments (red and yellow) In petals of kenaf are able to use as acid and alkali indicators, and dyes.4) The sorption of waste food oil and contaminated matters (dyes and metal ions) in waste water with kenaf sorbent were greater than that onto cotton, wood pulp and active carbon.5) The moisture content of kenaf was larger than that of wood pulp and cotton, and one of the reason would be owed to a large amount of hemicellulose of kenaf fibers comparing with wood Pulps and cotton.6) Lipid components were examined for the seed oils from the three varieties (4items) of kenaf. Nosignificant fifferences in the properties were observed among the varaieties. The fat content was about 20% and found to be a semi-drying oil. The fatty acid. sterol and tocopherol composition of the oil were analogous to cottonseed oil. Thus, it is possible to use the oil as edible oil, because the fat content was comparativelly high.
