Aqueous extract of cotton has allelopathic effect on Raphanus sativus, Brassica campestris, Lactuca indica, Brassica campestris, Echinochloa crusgall, Setaria viridis and Abutilon theophrasti and its inhibition effect gradually strengthens with increasing concentration. Aqueous extracts from stems, leaves and roots of cotton inhibit or accelerate seed germination and seedling growth, and activity of enzyme of seedling root of cotton. While aqueous extracts from stems and leaves of cotton are 0.02 gmL^(-1), root length, shoot length, lateral root number and dry weight of cotton respectively increase by 10.3%, 3.1%, 22.9% and 2.4% over the control. The above mentioned indexes are lower than the control by 34.4%, 39.2%, 40.6% and 19.0% respectively as the aqueous extracts are 0.1 gmL^(-1). At the same time, root activity and SOD activity decrease by 38.2% and 36.7%, while POD activity and MDA content increase by 52.3% and 36.5%. Growth indexes of plant receptors increase at low concentrations but decrease at high concentrations of aqueous extracts. The allelopathic effect of aqueous extract of stems and leaves is stronger than that of root.

结果表明：棉花植株水浸提液对萝卜、白菜、莴苣、油菜、稗草、狗尾草、苘麻均具有化感效应，随着作用浓度增加，抑制效应逐渐加强；棉花茎叶和根系水浸提液对棉花种子萌发、幼苗生长、幼苗根系活力、根系酶活性有抑制或促进作用，当茎叶浸提液浓度为0.02 gmL^(-1)时，棉花根长、苗高、侧根数、干重分别比对照增加10.3%、3.1%、22.9%和2.4%，当浓度为0.1 gmL^(-1)时，上述指标与对照相比分别降低34.4%、39.2%、40.6%和19.0%，而根系活力、SOD活性比对照降低38.2%、36.7%，POD活性、MDA含量较对照增加52.3%和36.5%，不同浓度棉花植株水浸提液对棉花生长呈现"低促高抑"的规律，且茎叶浸提液作用效应大于根系浸提液。

The results offer the condition that these plants of Ajuga could be distinguished by size and ornamentation of exhymenine.

结果表明，同属三种植物的形态特征相似，可通过叶形及花期是否具基生叶，花萼的形态，花冠颜色以及茎的生长方式和植株被毛情况等予以鉴别；通过对三种植物的花、根、茎、叶及全草粉末的组织构造观察，认为种间差异较小，可依据毛茸的分布及形态特征和茎的木化程度不同加以鉴别；对三者花粉粒进行了扫描电镜观察，发现其大小和外壁纹饰具有明显差异，为三者的鉴别提供了有力的依据，也为该属的分类及植物花粉形态研究提供了花粉形态学方面的资料。

Individual plant can be amounted to high 35, 40cm, the bine is brawny, the flesh is qualitative, palm is Brown, old bine Chang Mu is changed character, there are the stipule of puce and cicatricle on the section; Xie Lu is lubricious, intimate circle, diameter 5, 8cm, the flesh is qualitative, luster, young leaf is a bit involute, gradually open and flat; Petiole shows aegis shape to wear be born at upside slanting in the center of blade, if form is raising small looking glass of one side face, on concentrated unripe bine, petiolar accident is differ, to all around extend, plump circle makes outward appearance of entire individual plant.

株高可达35—40cm，茎粗壮，肉质，棕褐色，老茎常木质化，节上有深褐色的托叶和叶痕；叶绿色，近圆形，直径5—8cm，肉质，有光泽，幼叶稍内卷，渐平展；叶柄呈盾状着生于叶片中心偏上部，形若举着一面面小镜，密集着生茎上，叶柄长短不一，向四面伸展，全株外观丰满圆整。

To compare allelopathy of different parts of plant Datura Stramonium, the effective components from D.

为了比较曼陀罗不同部位化感作用的差异，用蒸馏水分别浸提曼陀罗根、茎、叶的有效成分，以蒸馏水为对照，研究曼陀罗根、茎、叶浸提液对芝麻和粟种子萌发和幼苗生长的影响。

To discuss the relationship between the allelopathy of native plants in Guizhou and seed germination of Eupatorium adenophorum, the method of culture dishes with filter paper was used to research effects of 10 kinds of leaf aqueous extract on seed germination of Eupatorium adenophorum.

为探讨贵州本地植物的化感作用与紫茎泽兰种子萌发之间的关系，采用培养皿滤纸法，研究了10种供体植物的叶片浸提液对紫茎泽兰种子萌发的影响。

Add natural disposition, soil helps advance somebody's career to also can survive, the bine does not have thorn, much more ramose, chang Xuan hangs down, young bine is compressed, knaggy, old bine lignification, show a circle a bit; Have a few thorn; Beautiful sheet gives birth to top, have two accrete occasionally, the standard is open, two side are symmetrical, have long canister.

附生性，土壤栽培亦可成活，茎无刺，多分枝，常悬垂，幼茎扁平，多节，老茎木质化，稍呈圆形；有少数刺座；花单生顶端，偶有两朵共生，水平开放，两侧对称，有长筒。

Although their role in formation and deposition of cellulose microfibrils had been proposed, they may also performed a function in the lignification.

另外，在茎的部分基本薄壁组织细胞和韧皮部等未木质化的细胞壁中，过氧化物酶也同样表现出较强的活性，这说明在茎的不同组织中分布的这种酶，可能是几种不同功能的同工酶形式。

The experiment result indicates that water-oat stem flour can obviously improve the pupation rate and oviposition.3. Component of artificial diet Ⅲ is made up of artificial diet Ⅰ and rice stem flour.

人工饲料配方Ⅲ是在配方Ⅰ的基础上添加水稻茎粉后改进而成，试验结果表明，配方Ⅲ中添加的水稻茎粉能明显的提高二化螟幼虫的化蛹率。

This paper describes the succulence of organs of Suaeda salsa seedlings treated with different salts. The growth of the seedlings was markedly enhanced by NaCl but markedly inhibited by NaF treatment. The degree of succulence was the greatest in leaves, second in stems and third in roots of seedlings treated with NaCl.

用不同的钠盐和含Cl-的盐处理盐地碱蓬幼苗后，测定不同器官的肉质化及相关生理指标，结果表明：NaF处理明显抑制盐地碱蓬幼苗的生长；NaCl处理下生长最好，其中叶片的肉质化程度显著高于对照，正在伸展茎次之，而根则不明显；其次是NaHCO3，肉质化程度也明显高于对照；CaCl2和KCl处理下肉质化程度都与对照相似；MgCl2处理下叶片的肉质化程度明显低于对照。
