查询词典 leaves

This paper determined the olfactory respones of Tetranychus viennensis to different plants odors with "Y" olfactometer and petri-dish, volatiles from leaves of different plants were absorbed with SPME and analyzed with GC-MS (gas chromatograph-mass spectrometer). At the same time, the effects of different host plants on the development of Tetranychus viennensis were determined by means of the leaf-dish rearing method , in addition, the contents of some chemicals in the leaves of different plants were also determined.

The results showed that the 50% leaf removal could increase the yield of sound boll by 24.4% that suggested the happening of overcompensation. The 25% leaf removal had no influence on cotton plant height and protein content in leaves, suggesting the 25% leaf removal in standard falling into the category of growth redundancy, but the climax in protein content in cotton leaves postponed about one week.

在棉花盛蕾期，用剪刀剪除棉花标准叶面积的25%和50%，模拟田间害虫的食叶危害程度，结果显示：50%去叶处理可使棉花成铃数增加24.4%，产生超补偿现象。25%去叶处理在短时间内对棉花的株高和叶中蛋白质含量都没有影响，植株株型亦无大的变化，表明25%叶面积属于生长冗余范畴。

Essential oil was extracted from the petroleum ether-soluble fraction of the leaves showed having antibacterial activity. It was demonstrated that the essential oil has significant antibacterial activity and the activity of the petroleum ether-soluble fraction is attributed to it. The constituents of the essential oil were analysized by GC-MS.10 relatively abundant components were identified on the basis of MS, among which Geranlgeraniol was found in the essential oil of Perilla frutescens leaves for the first time.

对具有抗菌活性的紫苏叶石油醚萃取物进一步精制，从中提取出挥发油，通过抗菌测试证明紫苏叶挥发油具有良好的抗革兰氏阳性菌和革兰氏阴性菌活性，是紫苏叶石油醚萃取物抗菌活性的来源；采用GC-MS对紫苏叶挥发油进行了成分分析，得到10种含量较高的主要化合物，其中的牻牛儿基牻牛儿醇首次在该植物挥发油中被发现。

The results showed that the gerbonation percentage and intensity of coated seeds all were enhanced; the number of roots and nodules, the accumulation of dry matter per plant and photosynthate in roots and leaves, as well as the rate of photosynthesis and the content of soluble protein in leaves all were increased in the coated seed s...

结果表明：包衣种子的发芽率及发芽势提高，其幼苗根数、根瘤数、单株于物质及叶和根中光合产物积累、叶片光合速率及可溶性蛋白质含量均有所增加，其中以1％效果最好。

Ready, the first pick up the bamboo leaves, picked up a corner, wrapped in a funnel-like shape, then you put the rice, do not put in too full, and do not put too little, and put me in the middle of the most glutinous rice favorite dates, then wrapped in bamboo leaves roll of 1, the last few laps with a wound resort to a knot, it ok, and I did not expect because of line bundles is too loose, casual look on, and alas, no alternative but to re-start.

准备完毕后，先拿起粽叶，拿起一个角，裹一个像漏斗的形状，然后把糯米放进去，不要放的太满了，也不要放的太少了，在糯米中间放入我最爱吃的红枣，再把粽叶一卷一裹，最后用线绕几个圈再打个结，就ok了，可没想到，由于线扎的太松，一下就散了，唉，没办法，只好重新开始了。

Considering other differences that in leaves of Podocarpus there are three resin ducts under vascular bundle of midrib, mesophyll cells are differentiated into palisade tissue and sponge tissue; in leaves of Nageia, there is only one resin duct under vascular bundle in each vein and no obvious differentiation in mesophyll cells, palisade tissue can be found on both sides, and sclereids can also be found in mesophyll tissue.

结合罗汉松属植物主脉维管束下面有3个树脂道，叶肉分化为栅栏组织和海绵组织，而竹柏属植物每个叶脉维管束下面有1个树脂道，叶肉分化不明显，两面都有栅栏组织，叶肉中还具有大量石细胞等特征，认为罗汉松属和竹柏属在叶脉、叶形态和结构方面存在明显差异，2个属分开是比较合理的。

Transgenic tobacco plants were obtained through screening with kanamycin. The transgenic tobacco plants could delay TMV infection for about 25 days compared with non-transgenic tobacco plants. Pokeweed antiviral protein Ⅱ is expressed with high level in summer leaves. The expression of PAPⅡ is regulated by season. The total RNA was extracted from pokeweed (Phytolacca americana L.) leaves in summer using the method of TRIzol and used as template to amplify the PAPⅡ gene by RT-PCR and then the gene was cloned into E. coli expression vector and secreted expression pPIC9K vector. The two vectors with PAPⅡ gene were then transferred into E. coli strain BL21 (DE3)-plysS and Pachia pastoris GS115 strain respectively. The specific protein was produced induced by IPTG and methanol.

由于美洲商陆抗病毒蛋白Ⅱ是一个受季节调控表达的蛋白，本实验以美洲商陆夏季叶片为材料，通过对其总RNA的提取、反转录、并用PAPⅡ的特异引物进行PCR扩增，对PAPⅡ进行了基因克隆、序列分析，结果扩增出来的PAPⅡ基因与已经报道的序列同源性是99.9％，然后将该基因构建到原核、真核表达载体上，分别转化了大肠杆菌和毕赤酵母并对它们进行了诱导表达，在两个表达系统中均获得了有活性的PAPⅡ表达蛋白，体外生物测定表明表达的蛋白均具有抑制病毒的活性，PAPⅡ基因在酵母中还没有表达的报道，这为获得具活性PAPⅡ蛋白提供了一种简便可行的方法。
