绿色，镰刀形的托叶，卵形或卵状披针形的很少，草本，边缘锐切成锯齿状或者有叶，很少全缘，先端锐尖或渐尖；叶柄疏生柔毛或短柔毛；叶片间断奇数羽状具(2或)3或4小叶，退化至3小叶在上部叶片上；短的小叶无柄或具小叶柄，倒卵形，倒卵状椭圆形，披针形或倒卵形， 1.5-5 * 1-2.5 厘米，背面的贴伏的具柔毛的在脉上，在脉之间的或密被短柔毛的或被绒毛的短柔毛，很少脱落无毛显著具点，正面具柔毛的或疏生腺体，或具粗毛或在脉上，很少脱落无毛，基部楔形到宽楔形，花序顶生，穗状总状，与否的分枝；轴具柔毛。

Except for Indigofera pulchella and trem a angustifolia that started to fall leaves in the middle of the rainy season, other 30 species started to drop their leaves from the late rainy season, and leaf dropping lasted for at least three months .

除红花柴和狭叶山黄麻从雨季中期开始脱落叶片外，其它30种植物从雨季末期开始脱落叶片，落叶期至少延续3个月以上。

Just the CTK content, the ABA content in its tiller node were most significantly related and most significantly negatively related to the tiller number of intervarietal hybrid respectively, but beside the CTK content, the ABA content in its tiller node were significantly related and significantly negatively related to the tiller number respectively, the IAA content were also most significantly related to the tiller number of interspecific hybrid, this may be the reason why the interspecific hybrid had a high fertile spike heterosis.

品种间杂种分蘖盛期分蘖节仅细胞分裂含量与分蘖数呈极显著的正相关，而脱落酸含量与其分蘖数呈极显著的负相关。而种间杂种分蘖盛期分蘖节中的细胞分裂素含量与其分蘖数显著正相关、脱落酸含量与其分蘖数呈显著负相关，另外其分蘖节中的生长素含量也与其分蘖数呈极显著正相关，IAA在种间杂种中的共同参与可能是种间杂种具有较强的分蘖成穗能力的原因。

In this thesis, we describe a facile and economical synthesis of-abscisic acid from keto-isophorone and 3-butyn-2-ol through ketalization, oxidization, Witting-Horner reaction, reduction with chromium sulfate and other steps in 13% total yields. Compared to the previous routes, the starting materials are more commercially available and cheaper and the synthetic process is more easily controlled in our method, but the yield of this route is still to be improved.As to isostere principle, cyclopropyl and methyl vinyl are a couple of isostere.

本论文设计并完成了一条全新的外消旋脱落酸(1)全合成路线，从廉价的工业原料氧化异佛尔酮和丁炔醇出发，经过缩酮化反应、氧化反应、Wittig-Horner反应、CrSO_4选择性还原反应以及水解等七步反应实现了脱落酸的全合成，总产率达13％，与以往路线相比，该路线所用试剂廉价、合成路线简单，但产率有待提高。

Non-invasive sampling is a useful tool for genetic analysis of endangered species,but it is often inapplicable due to the low quality and quantity of DNA obtained.In order to explore a method for extracting DNA from specimen of bird,we tried to extract DNA from dried skin of birds.We extracted total DNA of the koklass specimens successfully.

20世纪80年代以来，由于PCR技术的广泛应用，已经能对极少量遗传物质进行检测，由此产生了一类新的取样方法——非损伤性取样[1]，即在不伤害或触及动物的前提下收集脱落的毛发、粪便、口腔脱落细胞、陈旧皮张等作为分析样品，进行遗传学分析。

It has a lot of shortcomings such as catching fire, falling off, offending somebody, the pollution, cracking in the second wife the mildewy phenomenon as well as the building outward appearance falls off and so on. The disease has been existence already by the usual standard and the design. The construction custom and the universal procedure has formed complex not to be complex, irresponsible will be covered in the future by the universality.

着火、脱落、伤人、污染，开裂后室内发霉现象以及建筑外观脱落等，这些弊病的存在已被通常的规范标准、设计、施工习惯与普遍的做法已形成了复杂中的不复杂，被日后普遍性不负责任所掩盖。

Foreign gene could destroy larvas mid-intestine, and reduce its appetite. Observation by microscope showed that the gaps between mid-intestine cells was extended in treated larvae, and the nucleus were destroyed, the gap between peritrophic membrane and mid-intestine cells was appeared, parts of peritrophic membrane was broken off from mid-intestine cells.

外源基因对舞毒蛾幼虫的杀虫机理在于破坏幼虫的中肠组织，影响幼虫的取食，使幼虫取食量减少，甚至终止取食；中肠细胞间隙增大，细胞核遭受破坏；围食膜与中肠细胞之间出现空隙，甚至脱落，围食膜不再完整；中肠组织脱落，成为一个严重变形的残架。
