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 showed that among three regulator combinations (2, 4-D KT and IBA), 2, 4-D2~3 mgL^(-1 treatment was the best with the highest callus induction rate, most of the explants induced callus and grew well. 2, 4-D2mgL^(-1+KT0.5mgL^(-1 treatment could induce callus from stem parts while the callus induced from the stem top was water-soaked and easy to be brown stained. KT4mgL^(-1 treatment could induce callus on some stems but was easy to be brown stained. KT4mgL^(-+IBA0.5mgL^(-1 treatment could induce callus but they grew very slowly.
试验结果表明:在3种生长调节剂(2, 4-D、KT、IBA)的组合中,以2,4-D2~3mgL^(-1效果最好,愈伤组织的诱导率最高,大部分外植体都能诱导出愈伤组织,生长良好;2,4-D 2mgL^(-1)+KT0.5mgL^(-1)能使部分茎段诱导出愈伤组织,而茎尖诱导的愈伤组织水渍化,易褐变;KT 4mgL^(-1)能使个别茎段有愈伤组织产生,但易褐化;KT 4mgL^(-1)+IBA 0.5mgL^(-1)能诱导出愈伤组织,但生长缓慢。

At growth period of Moso bamboo, because the root has not grown completely and has little influence on rhizosphere soil, so the score was the highest. The score of rhizosphere soil decreases as the growth and root gradual development of Moso bamboo. The rhizosphere soil quality increased at later stage of Moso bamboo because of gradually weakened growth and the increased litter and microorganism activity.3.The demands for nutrients of Moso bamboo at different growth periods were different. It was different in the demand for nutrients of Moso bamboo at different growth period.
成竹期由于根系未完全形成,对其根际土壤的影响较小,因而成竹期得分最高,随着毛竹生长,根系渐渐发达,对其根际土壤的影响日渐扩大,造成根际土壤得分渐低,后期毛竹生长逐渐减弱,对其根际土壤的影响也随之减少,加上林中凋落物的增加和微生物活动增强,其根际土壤的质量有所增加。3、不同生长阶段毛竹对营养元素的需求有所不同。

Large supply of non-hybrid seeds for vegetables, grains and herbs; make sure they are of the non-GMO, non-hybrid, propagating variety; also be sure to have instructions on how to harvest seeds including information on "moldering" techniques to properly collect seeds from certain plants such as tomatoes; note lastly that due to damp low-sunlight conditions many crops will not grow without growing lights and protection from rain; special research is therefore required on which crops will grow best (for instance, patty rice should grow better than wheat under damp conditions); also be sure to take into account the climactic change which results from the change in latitude due to the pole shift as a location which does not change greatly in latitude will fare better than one which falls in the vicinity of the new poles for instance; the pole shift theory presented on Zeta Talk states that the terrestrial North Pole will move to the middle of the Atlantic off the bulge of Brazil and ultimately one will need to observe the climate and the position of the sun to figure out the new latitude, and either adapt or re-locate as needed
要有许多蔬菜,谷物和草药的的非杂交种子;确信它们是非转基因,非杂交的,是用于繁殖的品种。也得确信具有怎样收获种子的指导书说明,包括&制造&技术方面的信息,以便恰当地收集某些植物的种子,例如西红柿。最后得注意,由于幽暗的低阳光环境,在没有阳光,以及没有其进行雨水防护的情况下庄稼将不会下生长。因而需要进行特别的研究,看看哪种庄稼在这种条件下生长得最好(例如,在昏暗的状况下,水稻应该比小麦生长的更好)。也要确信考虑了极移造成纬度改变,因而导致气候变化。例如,与那些位于新极点附近的地方相比,纬度变化不特别大的地方情况要好得多。齐塔人之声讲述的极移理论表明了地球北极会移动到大西洋中部的巴西隆起处。最后需要观察气候状况以及太阳的位置,以弄清楚新的纬度,根据需要,即可适应当地的条件,又可再次搬迁。

Result A strain of Pseudomonas cepacia was detected in 1.6% compound quaternary ammonium disinfectant before application. The amount of the germ was 1.21×105cfu/ml. The strain had the similar resistance to chlorine-containing disinfectants and glutaraldehyde compared with Staphy aureus. The contaminated disinfectant could still thoroughly destroy the antigenicity of HBsAg with 60min's contact after diluted for 5-20 times.
结果 该洋葱假单胞菌对氯和戊二醛的抗力与大肠杆菌和金黄色葡萄球菌接近,污染样液除菌后1 000倍稀释对大肠杆菌和金黄色葡萄球菌仍有较好的杀菌效果,20倍稀释可完全破坏HBsAg抗原性,和抑制枯草杆菌黑色变种芽胞的生长,1 600倍稀释可抑制白色念珠菌生长,而原液则不能抑制分离菌株的生长。

Vascular endothelial cell growth factoris a kind of glucoprotein ,which has separated by culturing stellate cells of bovine glandula pituitaria in vitro by Ferrara etc. in 1989.lt can express that anxo-act vascular endothelial cell growth specificly and induce vasotropic growth ,so it is called VEGF.
血管内皮细胞生长因子(Vascular endothelial cell growth factor)是1989年Ferrara等牛垂体星状细胞体外培养分离出的一种糖蛋白,其在体内外都表现出特异性地促进血管内皮细胞的生长并诱导血管生成作用,故此称为血管内皮细胞生长因子。
