Thin leaf section were prepared from fresh tissues of YS-lnfected and healthy citrus plants, when observed under a fluorescence microscope (Type, Olympus AH-FL-2), a yellow fluorescence was distinctly observed in the YS-infected phloem tissues and not in the phloem tissuses of healthy plants and of those infected with tristeza, exocortis, canker, scab, greasy...

将健叶和黄龙病叶叶柄用保险刀片徒手切片，在透射式荧光显微镜下检查，可看到健叶叶柄的木质部导管细胞壁发黄色荧光，韧皮纤维细胞发绿色荧光，而病叶叶柄韧皮部中有1～多个鲜明的黄色或黄绿色荧光团块。这种特异性的荧光，在健叶柄韧皮部中是没有的，其它由病毒、类病毒、细菌、真菌等病原引起的病叶柄韧皮部中亦没有此种特异性荧光。

The isolates of S.sclerotiorum from different geographical regions and host-plants were cultured in the PDA culture medium. Mycelium from the culture was used for preparation of wheat seed inocula. The method for evaluation of resistance to soybean white mould in the field condition was established using silver paper trussing inoculum with minimally invasive on the soybean plants.

For power plants, china is already building supercritical and ultra supercritical coal fired power plants, this is top of the line technology!

对电厂而言，中国更是已经建立了超临界的甚至超超临界的煤力发电站，这些都是顶级技术！

To understand whether the GST can protect plant from the damage of ultra-violet radiation,a UV inducible GST gene was isolated from an Arabidopsis cDNA library.The plant expression vector containing the GST cDNA was constructed and transferred into Arabidopsis thaliana plants by the Agrobacterium-mediated vacuum method.Molecular genetic analyses showed that the overexpression of the UV inducible GST could increase the tolerance of the transgenic plants to UV radiation

为了阐明GST在紫外辐射下是否对植物有保护作用，以紫外强烈诱导表达的GST cDNA为探针，筛选拟南芥cDNA文库，获得了这种GST的全长cDNA；利用此cDNA构建植物表达载体，并通过农杆菌介导法转化拟南芥，使其在拟南芥中得到大量表达；通过对转基因植株的紫外辐射耐性分析，证实了该GST的过量表达可明显增强拟南芥对紫外辐射损伤作用的耐受性。

Just like hungry humans, underfed plants grow more slowly, are more susceptible[3] to disease and pests, and reproduce less often than healthy plants.

与人类营养不良类似，营养不良的植物生长变得迟缓，越来越容易受到疾病和有害物的侵扰，再生的速度远不如健康的植物。

Cang Xin's painting《Communication》is developed from his previous painting of behaviors:《Experience of the Tongue》. In the painting in 1997, he imitated "Shen Nong Shi", who tasted over a hundred plants in the ancient time, to use his tongue to lap all kinds of daily necessities、plants and even insects which can be found easily, using sense of taste to experience the original taste of the various uneatable objects in order to seek new cognitive style of the external things .

苍鑫的作品《交流》脱胎于以前的的行为作品《舌头的体验》，1996年的那次行为中，他曾仿效神农氏尝百草的劲头，用舌头一一舔舐随手找到的各种现成生活用品、植物甚至昆虫，用味觉来体验各种非食物的物品的本来味道，以寻求对外在事物新的认知方式。

For some kinds of vegetables and pasturages, the contents of some heavy metals surpass the relevant quality standards, so when some crops were planted on the substrates, the uneatable species should be selected preferably and if some kinds of vegetables and pasturages must be adopted, the output could not be provided to mankind and also not be used in farming, in order to avoid harming peoples'health.5 The expediency evaluation model of pioneer plant on substrates was established and some plants were studied. The results show that the expediency evaluation of pioneer plants were respectively that clover was expedient to substrate 1, juniper, cotton and fescue were expedient to substrate 2 and juniper, annual bluegrass, fescue, cotton and clover were expedient to substrate 3.6 Some indexes to evaluate the capability of the phytoremediation on heavy metals and the comprehension about hyperaccumulator were put forward.

有多种植物的重金属含量超过了相应的国家标准，因此在基质上种植植物时，尽量选择非食用性植物品种，即使种植了蔬菜和牧草等植物，也不应将收获后的产品供人类食用或用于畜牧生产，以免危害人体健康。5建立和研究了复垦基质先锋植物的适宜性评价模型，结果表明，不同基质中适宜的先锋植物分别如下：基质1为苜蓿，基质2为桧柏、棉花和高羊茅，基质3为桧柏、早熟禾、高羊茅、棉花和苜蓿。6探讨了评价重金属元素植物修复能力的指标体系和"超富集植物"的概念。

Based on extrapolated organ shape criteria,we select ears that are in uninucleate period,carry out pretreatment in a 6~8℃ low-temperature condition for about 12 days, and callus induction rate can be enhanced in this way.② 1~2mm diameter should be the appropriate size for translocated callus,and plants grow to 4cm breeding for mature plants should be conducted in a timely manner.③ Get well down with sterilization,reduce contamination and strengthen greenhouse management,etc.
