发展广西花卉业的几点看法   总被引：1，自引：0，他引：1  

梁红 《中国花卉盆景》1996,(9)

广西属亚热带地区,气候与广东相似,除夏季外三季都有培植花卉的良好自然气候,特别是在冬季,当北方必须用温室的时候,在这里,一层塑料薄膜就能达到相同的效果。玫瑰、剑兰、菊花四大切花中的三种甚至露天就能良好开花,但广西的花卉业却一直是全国落后省份。原因何在? 反观邻省广东,却是全国花卉业最发达的地区之一,在广州、深圳都有全国性的花卉交易中心,年交易额数亿计。再看云南,只用五六年时间,凭借良好的气候条件,大种鲜切花,已逐步成为全国最大的鲜  相似文献   

细胞凋亡的研究及进展     

曾林  钟仰进梁红 曹阳 《广东蚕业》2003,37(3):43-47,42

细胞凋亡(apoptosis)又称细胞程序性死亡(programmed cell death)是多细胞动物生命过程中必不可少的正常过程，它与细胞增殖具有同样重要的意义。它与生物体的生长发育以及生物体疾病的产生和控制都有极大的关联。因此，这一领域的研究受到了的生命科学研究的广泛重视，特别是近年来其研究发展非常迅速，研究的方法及检测手段都有了很大的提高，本文将从细胞凋亡的定义、形态学特征、诱导、检测方法、分子调控等方面综合分析国内外的研究进展。  相似文献   

Effect of ivermectin and oxfendazole on shedding of larvae of the lungworm (Dictyocaulus viviparus) by red deer (Cervus elaphus)     

Bowie JY  Mackintosh CG  Mason PC 《New Zealand veterinary journal》1987,35(1-2):8-10

Thirty eight newly weaned hinds were randomly allocated to one of two equal groups. One group received ivermectin, the other, oxfendazole at dose rates of 0.2 mg/kg and 4.5 mg/kg, respectively. All deer were drenched four times and were grazed on pasture. Both anthelmintics reduced D. viviparus faecal larval counts to low levels 20 days after dosing, but the mean larval output and the proportion of deer shedding D. viviparus larvae at 27 and 33 days after treatment, were significantly lower in the ivermectin treated group. There was no significant difference in weight gain between the two groups throughout the trial. This study suggests that ivermectin prevents reinfection with D. viviparus for approximately 14 days longer than oxfendazole.  相似文献   

Equine hydatidosis: a new record for New Zealand     

Bowie J  Mason PC  Oudemans G  Montgomery RH 《New Zealand veterinary journal》1984,32(9):151-153

Cysts found in the liver of a horse which had never been out of New Zealand were used to infect two dogs which were slaughtered 35 days after infection. Large numbers of Echinococcus granulosus were recovered. These cestodes were compared with mature dog-sheep cestodes, using light and scanning electron microscopy and identified as the dog-horse strain of E.granulosus.  相似文献

Self-Assembled Metal Colloid Monolayers: An Approach to SERS Substrates     

Freeman RG  Grabar KC  Allison KJ  Bright RM  Davis JA  Guthrie AP  Hommer MB  Jackson MA  Smith PC  Walter DG  Natan MJ 《Science (New York, N.Y.)》1995,267(5204):1629-1632

The self-assembly of monodisperse gold and silver colloid particles into monolayers on polymer-coated substrates yields macroscopic surfaces that are highly active for surface-enhanced Raman scattering (SERS). Particles are bound to the substrate through multiple bonds between the colloidal metal and functional groups on the polymer such as cyanide (CN), amine (NH(2)), and thiol (SH). Surface evolution, which can be followed in real time by ultraviolet-visible spectroscopy and SERS, can be controlled to yield high reproducibility on both the nanometer and the centimeter scales. On conducting substrates, colloid monolayers are electrochemically addressable and behave like a collection of closely spaced microelectrodes. These favorable properties and the ease of monolayer construction suggest a widespread use for metal colloid-based substrates.  相似文献   

Observations on hypoglycaemia associated with a hepatoma in a cat     

Thompson JC  Hickson PC  Johnstone AC  Jones BR 《New Zealand veterinary journal》1995,43(5):186-189

Disorientation, muscle fasciculations and weakness seen in a 12-year-old neutered female domestic shorthaired cat were attributed to hypoglycaemia associated with a large hepatoma. Glucagon tolerance tests on this cat and a healthy cat showed that their plasma glucose concentrations increased and decreased at about the same rate. Plasma insulin concentrations in the healthy cat increased and decreased in parallel with the plasma glucose concentration. In the affected cat, plasma insulin concentrations increased initially but decreased more rapidly. Reflecting these observations, the amended insulin to glucose ratios in the affected cat were much lower than those of the healthy cat, until the 4-hour sample. Serum somatostatin, somatomedin and gastrin concentrations were measured but no conclusions as to pathogenesis of the hypoglycaemia could be made. The alterations in insulin secretion in the affected cat suggested that altered hormonal control of glucose homeostasis may have occurred with this tumour.  相似文献

玉环柚标准化示范基地建设总结     

陈青英  梁红 《浙江柑橘》2003,20(2):20-22

玉环柚(楚门文旦)是浙江省的传统名果,也是中国柚类优良品种之一,曾连续八次获全国柚类鉴评总分第一。1998、2001年二次被浙江省人民政府列为名牌产品,1999、2001年获中国国际农业博览会金奖,但大面积生产的玉环柚仍存在着果品良莠不齐,产业化程度不高,经济效益差。为了提高玉环柚果品质量和经济效益,自1998年起进行了玉环柚标准化示范基地建设,通  相似文献
