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。

Blossom to make a flower can long, when cutting branch extraction a flower, cut had better cut 45 degrees cant, can enlarge bibulous area so, OK also the flower cauline radical ministry is knocked crack, will help bibulous.

为了让花能长时间绽放，在切取花枝时，切口最好削成45度的斜面，这样可以扩大吸水面积，也可以把花茎基部敲裂，来帮助吸水。

Realistically designed as a floral spray, the two flower-heads set with oval cabochon rubies within an undulated border of brilliant cut diamonds, the stem set with baguette diamonds, the leaves with eight and brilliant cut diamonds.

栩栩如生的花束造型，两朵花的花瓣镶嵌椭圆形鹅蛋红宝石，波浪形边缘镶嵌明亮切割钻石，花茎镶嵌长方形钻石，叶子镶嵌八斜面及明亮切割钻石

Although most often referred to as Calla "Lily," the calla is not related to true lilies or to the lily family.

它有肥大的根茎，叶柄较长，叶形如倒心脏形，先端较尖；花茎高出叶片，花苞白色，苞片中

Marty, you did not cauterize the stems.

马蒂 你这些花茎还没剪！

Regular contributor from Australia, Mark Pampling , explains why bending stems can allow you to develop a very chic arrangement and Singapores's Damien Koh combines his love of food with floristry to create a masterpiece on a plate!

来自澳大利亚的花艺师Mark Pampling将解说为什么用弯曲的花茎可以做出这么别致的作品，而新加坡花艺师Damien Koh结合他喜爱的食物用一个浅盘创作了一个很棒的作品。

Even under the optimumtemperature of 8℃,they needed more than 30 days for completefloral bud differentiation and flower stalk development.

即使在最适感应温度8℃下，YC和S-1均需30天左右的感应时间，方可诱导植株形成完全的花芽并进入花茎的分化形成期。

The high levels of polyamin.s benefit flower bud and flower stalk differentiation .

GAs对花芽分化的影响因品种不同表现复杂，但花茎的发育和抽出。

Nevertheless, it plays opposite roles on B.campestris ssp. and B.campestris var.rapa. The effect of GAs is very complicated according to different varieties, but it promotes flower stalk initiation and bolting.

本试验表明：高的IAA/iPA比值是大白菜、小白菜和芜菁花芽分化起始的有利条件，而低的GAs/iPA比值对花茎发育起始有利， GAs/ABA的作用与GAs/iPA的基本相同。

The results showed that the contents of nutrient components in plants propagated by thick scapes were higher than those by thin scapes, and the contents in open field cultivation were higher than those in protected cultivation.

结果表明，1.0cm粗花茎繁殖的产品品质指标含量总体上高于0.5cm以下细花茎繁殖的产品，露地栽培产品的品质指标高于保护地栽培。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
