The results indicated:0.1 mg/L 2,4-D or 0.1 mg/L 2,4-D+0.2 mg/L KT was optimal to induct the callus of carrot hypocotyls.The majority of the callus induced on the medium containing 0.1 mg/L 2,4-D regenerated embryoid,whereas,the callus induced on the medium containing 0.1 mg/L (2,4-D)+0.2 mg/L KT produced adventive buds.During the growth of regenerated plant,MS medium is available for rooting of seedling,and seedling regenerated on B5 medium must be placed on the B5 medium containing 0.1% IBA to develop root.

试验结果表明：0 1mg/L2，4 D或0 1mg/L2，4 D+0 2mg/LKT的激素组合有利于胡萝卜下胚轴的愈伤组织诱导；在0 1mg/L2，4 D的培养基上形成的愈伤组织主要以胚状体的形式再生，而在含0 1mg/L2，4 D+0 2mg/LKT激素组合的培养基上形成的愈伤组织主要以发生不定芽的方式再生；再生过程中，B5基本培养基上的苗子不易生根，需要附加0 1mg/L的IBA，而在MS培养基上苗子可直接形成根。

According to several years practice, comprehensively sum up measures of forcing culture technology of scale and dwarf on potted Bougainvillea as: a propagation of cuttage, which choose a mixture of 50%peat, 33% vermiculite and 17 sharp sand as cutting soil, and choose a semi-wooden shoot cut into 5~10cm length with 2~3 leaves as cuttings then touch 1% AA root powder, is lower cost and higher survival rate than that of tissue culture; Bougainvillea growth can be efficaciously regulated by pruning and using 2~5g/L PP333; bougainvillea can be induced to flowers by spraying 2.5~4.0g/L B9 and administering no more 11 hours daylight every day continuously; the florescence can be more prolonged about 20 days by spraying 50mg/L NAA while selling; and prevention and cure of pest and disease, etc.

根据多年的生产实践，从科学育苗、栽培管理、售前处理和病虫害防治等方面综合总结了叶子花的规模化矮化促成生产技术措施：选择泥炭土、蛭石和黄沙按3：2：1比例混合均匀的扦插基质，采用半木质化当年生枝条，剪成5~10cm长的2~3叶节一段，沾染1%自制生根粉的扦插育苗较组培育苗成本低，成活率高；结合修剪用2~5g/L的多效唑进行叶面喷洒能有效控制生长，矮化植株；选择2.5~4.0的丁酰肼叶面喷洒和每天保持不多于11h的短日照处理，能有效促进开花；销售前全株喷洒脱50mg/L NAA可延长花期20天左右；整个生产过程加强肥水管理、温湿度控制和环境清洁能有效防治病虫害发生。

In the last year, though, the U.S. troop surge and the backlash from moderate Iraqi Sunnis against Al Qaeda and Iraqi Shiites against pro-Iranian extremists have brought a new measure of stability to Iraq. There is now, for the first time, a chance — still only a chance — that a reasonably stable democratizing government, though no doubt corrupt in places, can take root in the Iraqi political space.

尽管在去年里，美国军队的增兵、温和的伊拉克逊尼派对于基地组织的强烈反对以及伊拉克什叶派对亲伊朗极端分子的反抗形成了一个维持伊拉克稳定的新方法，但是现在第一次有机会---也是唯一的机会---一个合理的稳定的民主政府在伊拉克政治空间中能够扎地生根。

Holy Koran, sheltered life of this ancient paradise, sincere support for world suddenly see the light, between God and man at once to be closer, if only a dromedary can find the footprints of God; the Camel Bells, such as bell Drum general Reverberation recovery harmony with wonderful sounds, such as the Vatican wave vicissitudes of history, general Dangkai calendar change; simple and sincere, site root, it was such a world, a leaf of a flower of enlightenment of a Buddha nature.

圣洁的古兰经，庇护着这片古老的生命乐土，真诚的供养让天地豁然开朗，神与人之间一下子被拉近了，仿佛只需要一峰骆驼就能找到神的足迹；而驼铃如晨钟暮鼓一般传波着妙音复苏的祥和，如梵波一般荡开历史的沧桑历变；民风淳朴、立地生根，才得这般一花一世界一叶一菩提的教化自然。

Plantlet regeneration from cotyledon of Citrullus lanatus cv. Zhangkang No. 4 was studied. The results showed that aseptic seedlings should be cultured in dark for 3d, then exposed to a photoperiod of 16/8h/d for 3d. The callus induction rate was higher in cotyledons placed facing downwards to the medium than in those facing upwards. The highest induction rate occurred in MS medium containing 6-BA (2.0mg/L), kinetin (1.0mg/L)and GA3 (1.0mg/L). The induction initiated in dark and took 7 days, while callus growth and differentiation proceeding for 7 days under 16/8h light-dark cycles. A highest rate of embryogenic callus was obtained after 3 successive subcultures.

以无子西瓜郑抗4号无菌苗子叶为外植体，进行了体细胞胚发生及植株再生的研究，结果表明，无菌苗应先进行3d暗培养，然后采取光照16h/d和黑暗8h/d培养3d；将子叶的叶面朝下放置于培养基上的愈伤组织诱导率高于叶面朝上的培养方式；子叶诱导胚性愈伤组织的最适培养基配方为MS+6-BA2.0mg/L+KT1.0mg/L+GA31.0mg/L；诱导需要在黑暗条件下启动，进行7d暗培养，而生长分化于光照16h/d和黑暗8h/d条件下培养7d；继代3次得到的胚性愈伤组织最多；最适生根培养基配方为1/2MS+IBA0.3mg/L。

Result The results revealed that different concentration of C6-HSL could obviously inhibit the growth rate of root and the number of roots, but have no effects on plant height, number of nodes and leaf size. The POD and SOD activities and the concentration of H2O2 showed a significantly increased when the potato implants were pretreated with C6-HSL, however, no effect of C6-HSL pretreatment on PAL and PPO activities were found. The ability of resistance aginst Erwinia carotovora subp. carotovora was signifinantly improved after treated by C6-HSL. Incidence was obviously lower than the control group.

结果］不同浓度的C6-HSL能明显抑制马铃薯的出根率和生根数，而对株高、茎节数及叶片大小没有影响；植物标志性防御酶类中POD和SOD的活性以及H2O2的产生量经C6-HSL诱导后显著提高，而PAL和PPO的活性则没有明显变化；抗病试验中，经C6-HSL诱导的马铃薯植株能有效抑制胡萝卜软腐欧文氏菌的侵染，发病率明显低于对照组。

Based on my experience in both government and business, I believe a successful modern economy needs the following:a transparent system of laws and regulations that are enforced fairly, eliminating opportunities for corruption and favoritism;protection of property right, so that people an keep the fruits of ther labor and build for the future for themselves and their children; a pricing system reflecting supply and demand of individual consumers and businesses, not state-imposed diktats.

依我在政府和商业领域的经验，我认为，现代化的经济要取得成功，需要法律和法规透明，执法公正，使腐败和偏袒现象无法生根发芽。需要有对财产权的保护，是人民可以保有自己的劳动成果并为自己及子女建设未来。要有能够反映出个人消费者和企业供需状况的价格体系，而不是由政府对价格强加的统治令。

Nigra during the experiment. Successfully established the transformation procedure Agrobacterium-mediated of Populus simonii×P nigra: cut vigorous leaves to 2-3 patches through the main vein after growing about 20 days, pre-culture time was 3~4days;centrifuge Agrobacterium when being developped to the logarithm growth timeOD_(600=0.5, then dilute Agrobacterium to the concentration of OD_(600)=0.3-0.4 with MS liquid culture medium or asepsis distilled water for infection;infection time was 6-15 minute;after being co-cultured 3 days, inoculate on the selecting medium to be filtrated in succession during inducing unsureness buds and rooting with Kanamycin(containing Kanamycin 40mg/L and Cefazolin Sodium 700mg/L).
