Perennial herb, 60-150 cm high, all the dense white hair, the number of lignified rhizomes, stems upright, base sometimes lignified.

Improving the activity of SOD can postphone aging of leaf and decreasing of photosynthesis, decrease the exportation of carbohydrate of stem-sheath matter, promote transportation of carbohydrate to axillary buds, and increase the ratooning ratio.

提高叶片中SOD活性，能有效延缓叶片衰老，延缓叶片光合同化作用的下降，减少茎鞘碳水化合物的输出，促进茎鞘碳水化合物向腋芽输送，促进腋芽萌发，提高水稻再生率。

The genetic analysis was carried out for 8 characters on 9 energy cane parents and their 20 combination crosses with the NCII mating design. The results showed that the inheritance of stalk biomass, brix weight, available stalk numbers and weight per stalk was subject to both additive gene effect and non-additive genes effect, but mainly controlled by non-additive genes. The inheritance of plant height, stalk diameter and brix was subject to both additive gene effect. The broad sense heritability (HB2) of stalk biomass and brix was over 50%, and those of brix weight were 33.7% at the seedling stage 54.4% at its ratooning stage, respectively , which means that the selection would be done better at the early stage in the sugarcane breeding program.

利用遗传交配设计对能源甘蔗9个亲本组配的20个组合、8个性状进行遗传分析，结果表明：地上部鲜重、锤重、丛有效茎数和丛重的遗传既受基因的加性效应也受基因的非加性效应所控制，但以非加性效应为主；株高、茎径和锤度的遗传主要是受基因的加性效应控制，地上部鲜重和锤度实生苗新植和宿根的H_B~2都在50％以上，而锤重的H_B~2分别为33.7％和54.4％，而且锤重和地上部鲜重母本gca方差都大于父本gca方差，说明能源甘蔗育种中母本选择的重要性。

More assimilation products were stored in sheathes than those in leaves. 2After rewaterring, net photosynthetic rate and evaporation rate came back quickly, especially D3 and D6 groups whose two photosynthetic indexes were higher than that of control group and then droped back to normal in serveral days.

同化产物在叶片中的含量高于茎鞘，但叶片中的氮素含量低于茎鞘。2恢复灌溉后，受到胁迫的处理组的光合速率、蒸腾速率都迅速升高，干旱3 d和6 d的处理组光合水平超过对照，然后又有所下降，水分利用效率因为蒸腾速率的骤然升高而降低，之后有所恢复。

The result showed that the ethylene content in upper organ of ramie plant is higher than in lower organ. The ethylene content in leaf and stem apex is higher than flower bud. The ethylene content in ramie plant with female flower is higher than ramie plant with androgynary in stem apex, leaf and flower.

结果表明：乙烯在苎麻体内分布总趋势是自上而下依次减少，上中部器官乙烯含量大于下部器官，其中茎尖和叶片乙烯含量大于花芽，性别表现为雌性的苎麻在茎尖、叶和花芽中的乙烯含量都大于性别表现为两性的苎麻。

Cubense race 4 (FOC4), and the expression levels more than comparison. The physiological result was identical with that of molecular biology research, meanwhile, resembling the research results of other plants. It demonstrated that the PAL enzyme played a key role in resisting banana wilt.

cubense race 4 (FOC4)茎中 PAL 表达的变化，结果显示茎中 PAL 活性呈规律性变化，且均高于同期对照，与其它植物相关研究结果类似，表明 PAL 与香蕉抗枯萎病密切相关。

Moreover, tests were made with the above four culture media upon stem apex, leaves, blossom bud and lateral bud. The result shows that leaves grow best in the 1/10MS culture medium.

同时用四种培养基分别对茎尖、叶片、花芽和带侧芽的茎端作组织培养，得到叶片在 1 / 1 0MS培养基中生长状况良好。

The 3rd kind is wild clove, local name careless head, renown bur clover, the bine lies the ground, each fine bine, there are 3 flocculuses on, chinese the Yangtse River has downstream feral and cultivated those who serve as edible.

第三种是野苜蓿，俗名草头，又名金花菜，茎卧地，每一细茎，上有三小叶，中国长江下游有野生和栽植作为食用的。

Middle and upper cauline leaves cordate-amplexicaul; fruit 3-7 × 3-5 mm, broadly winged only apically; seeds yellowish brown, smooth, 1-1.3 mm

中间和上面茎生叶心形抱茎；果 3-7 * 3-5 只顶部的毫米，具宽翅；种子黄棕色，平滑，毫米 2 T。 perfoliatum 全叶菥艹冥

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
