The results were as follows:1 The explants with two phyllomes(about 0.2-0.5mm in size )were found to be suitable for virus-free seedling culture , which were cultured on solid MS medium supplement with 6-BA,NAA and IAA ,The result indicated that the plantlet was over 30% after three months.

主要结果如下： 1。取带2个叶原基(长度约为0.2-0.5mm)的茎尖为外植体，在附加6-BA、IAA和NAA的MS培养基上进行3个月的培养，成苗率达30％以上。另外，在切取茎尖前对薯苗热疗(37℃)4周，在基本不影响成苗率的同时，可大幅度提高脱毒率。

Can improve the survival ratio of seeding. Culturing in hormone media can make meristem tip survive once time, and the result is better than two-time-cultivation.3、The meristem tip with two phyllomes(0.3-0.4mm in size)were found to suitable for virus-free seeding culture that were cut from aseptic seeding, which led to higher survival and virus-free ratio, up to 72.1%and 54.2%.

在培养基中添加椰汁、香蕉汁等有机添加物可以明显提高成苗率。3、采用二次剥离茎尖的方法，从无菌试管苗上切取带2个叶原基(大小0.3-0.4mm)茎尖分生组织培养，成苗率为72.1%，脱毒率为54.2%。

The research also paddeds the study vacancy in banana outgrowths, and supplies theory foundation and the application examples to the reasonable utilization of banana stems and leaves.

综上所述，本研究——香蕉茎、叶有效成分的提取和洗涤活性、抗氧化特性研究具有较好的生态和社会效益，若能实际应用将产生显著的经济效益，同时又填补国内外空白，为今后香蕉茎、叶的合理利用提供理论依据和应用实例。

Falling dust had no significant difference in winter wheat's stem soluble sugar content at these two stages.

降尘对两个时期冬小麦的茎的可溶性糖含量没有明显的影响，二氧化硅对拔节期和盛花期的冬小麦的叶可溶性糖含量、淀粉含量及茎淀粉含量均有显著性影响，新疆浮尘则影响不显著。

The rate of Si uptake, the proportion of Si distributed in leaf and stem of wheat in intercropping were also significantly higher than that of monocropping.

施氮会减少小麦叶片、茎和穗中硅的含量，但间作能明显缓解由于施氮引起的小麦叶、茎硅含量的下降趋势。

It has been certified that the maximum tensile and elongation of wheat straw without stem node is more than that of wheat straw with one stem node.

通过拉伸实验，测试了无茎节和1茎节麦秸秆在天然、浸海水、浸胶及浸胶后再浸海水4种工况下的极限拉力和极限延伸率。

The results of the two orthogonal designs of artificial diet of rice stem borer both indicate that sucrose and wheat germ flour are key factors of survival days of rice stem borer. Rice stem flour、 wheat germ flour、 yeast flour and rice stem chaff flour affect the survival.

二化螟人工饲料两次正交试验的结果均表明，蔗糖和麦芽粉是影响二化螟幼虫历期的关键因子，水稻茎粉、麦芽粉、酵母粉和稻糠粉是影响二化螟幼虫成活率的关键因子，水稻茎粉是影响二化螟蛹重的关键因子。

Stems 18-100(-160) cm tall, well-branched above, densely gray villous on lower part, mixed above with short glandular hairs, often with raised lines decurrent from margins of petioles. Leaves subsessile or lower ones with petioles 1-3 mm; cauline blade lanceolate-elliptic to narrowly lanceolate or oblong-lanceolate, 3-12 × 0.5-2.5 cm, both surfaces villous, base usually rounded, margin denticulate with 15-60 teeth per side, apex subacute.

茎18-100(-160)厘米高，在上面的多分枝，叶近无柄或下部的具叶柄1-3毫米；茎生叶披针形椭圆的到狭披针形或者长圆状披针形， 3-12 * 0.5-2.5 两面，厘米具长柔毛，基部通常圆形，边缘具小齿具齿每边，近尖的先端。
