Physiological and biochemical changes of monocotyledonous plant maize (Zea mays L.) were studied and the protective effects of nitric oxide against iron deficiency induced injury were analyzed simutaniously. The plants were grown in monofactor controlled solutions using solution cultural method and the full expanded fourth leaves were used in all of the experiments. The biochemical and the molecular mechanisms of iron induced injury and the protective mechanisms of NO against iron deficiency induced injury were studied.

Mainly belonged to Loranthaceae. Plants of Phacellaria Benth. and their hosts were mainly distributed in tropical and subtropical area. Plants of Phacellaria Benth. maybe originated in tropical area in the south of China before Tertiary. Their ancestors were parasitic on ancestors of some plants of Loranthaceae by chance during Tertiary. It took them millions of years to form a sturdy relationship between parasites and hosts. Ph. rigidula was a hemi-parasitic subshrub. In area observed, its host was mainly Taxillus caloreas var. fargesii.

The results were as follows:(1) Seeds of 80 species or subspecies could be classified into two groups. Group Ⅰ included the seeds of Gramineae, Cyperaceae, Polygonaceae and Amaranthaceae, and Group Ⅱ included the seeds of Compositae, Euphorbiaceae, Brassicaceae and Umbelliferae.(2) Only FTIRs of the seeds of Brassicaceae were clustered together in the dendrogram,while those of the other families all appeared farraginous.(3) Among FTIRs of the 11 groups of the congeneric species,8 groups were clustered with other genus species, and 6 out of 7 groups of conspecific seeds appeared farraginous in the dendrogram.

结果表明：(1)80种草本植物的种子可以分成两类，第1类由禾本科、莎草科、蓼科和苋科植物的种子组成；第2类由菊科、大戟科、十字花科和伞形科植物的种子组成；(2)聚类图上，只有十字花科植物的种子能较好地与其他科的相区别；(3)在11组同属不同种植物中，有8组植物与亲缘关系不同的其他属的植物混在一起；在7组同种不同亚种或品种植物中，仅有1组植物被聚合在一起。

There were larger differences in element contents between different organs of mangroves, while sodium distributed equally in the different organs of \%C. eyrei.\%(2)The osmoregulation of 5 mangroves was mainly fulfilled by salt accumulation.(3)Salt exclusion by roots was the most important salt tolerant mechanism of all mangroves. Keeping lower salt contents in above ground organs was the common feature of all mangroves.(4)Except the efficiency in salt exclusion by roots, no apparent deficiencies in element accumulation and distribution could be found between salt excluders \%(K. candel, B. sexangula\% and \%R. stylosa)\% and salt secreters \%(Avicennia marina\% and \%Aegiceras corniculatum).

结果表明：(1)红树植物体内存在一有效的盐分重新分配机制，各器官之间盐分含量差别较大，而甜槠植物体内Na分布相对比较均匀；(2)这5种红树植物主要是通过积累盐分来抵御生境高盐引起的渗透胁迫；(3)根系拒盐是所有红树植物最重要的排盐机制，在满足细胞渗透调节的前提下，保持地上部分器官较低的盐分浓度是所有红树植物的共同特点；(4)拒盐红树植物与泌盐红树植物除根系排盐效率上有所差别外，在植物体各器官元素积累及分配方面，没有明显的差异。

Rhinopithecus bieti mainly fed on 43 plant-parts, mainly plant buds and leaves during the plant vegetative period, and during the reproductive period, they lived on 31 parts, dominated by flowers and fruits. In the dormant period, they ate 19 items, and the seed capsule of Juniperus recurva var. coxii (A. B. Jackson) Melville and the buds or needles of Pinaceae were the primary food.

植物营养生长期时，滇金丝猴取食43个植物部位，主要是芽和叶；生殖生长期，取食31个植物部位，主要是花和果实；而在植物的休眠期，取食19个植物部位，主要是小果垂枝柏的种皮和松科植物的芽与叶。

Molecular Plant-Microbe Interactions is published by American Phytopathological Society, publishes significant research on the molecular genetics and molecular biology of pathological, symbiotic, and associative interactions of microbes and plants.

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。

The present paper reviewed advances in plant defense mediated by the signal function of plant VOCs. In some cases plant VOCs can have a direct defense mechanisms against herbivory. It is believed that VOCs can transfer within plant and between the plants of the same species and different species to improve the defense mechanisms of the respective plants, indicating their crucial role in ecosystem function.

总结了植物挥发性物质作为信号物质在提高植物抗性方面的国内外研究成果，阐述了植物挥发性物质不仅能够直接提高植物的抗性，而且可以作为信号物质在同株、同种异株和不同种植物之间进行传递，进而间接提高目标植物的抗性。

Diaspididae is one of important pests in agriculture, forestry and ornamental plants. It not only pierces and sucks plant sap, destroys plant green organizations, but also pollutes the plant of leaf and fruit surface, affects plant of photosynthesis, leads to the plant of deformities, wither and die when it occurred largely.
