Therefore, the capacity of utilizing low light intensity of seedlings could be enhanced by cold acclimation, and the increase of photosynthetic light saturation point and the decrease of photosynthetic rate of seedlings in Euonymus radicans might be the adaptive adjustment to the cold acclimation so as to raise the stability of photosynthesis of seedlings under low temperature stress and then enhance the cold -resistance of seedlings.

In iron-deficient cells, photosynthetic pigments content decreased, efficiency of photosynthesis was low, With the increase of the concentration of the iron-chelator 2, 2'-Dipyridyl in media, Fv/Fm decreased, indicating photoinhibition increased, the results were consistent with previous research; Heterocyst induction had one delayed time dependent on the status of iron-deficiency, More severe of the iron-deficiency condition, more late of the heterocyst induction, It is possible that certain iron-related genes may directly regulate heterocyst development; under different iron limitation conditions, Protein pattern were different, more serious of the iron-deficiency conditions, less bands of the protein pattern, We could not find the iron-deficiency induced protein; In general the toxic effects of ROS were potentiated by excess iron, But our results revealed that even under iron-deficiency conditions, Oxidative damage existed.

铁限制的细胞光合色素含量下降，光合作用能力下降，随着铁螯合剂2，2'-dipyridyl浓度的增加，叶绿素荧光F〓／F〓逐渐降低，显示光抑制变强。与前人的研究结果相似；依赖铁缺失状态，异形胞诱导有一段推迟的时间，铁缺失越严重，诱导越迟，推断某些铁相关的基因会直接调节异形胞发育；在不同铁营养条件下，蛋白质图谱的变化趋势很明显，缺铁越严重，则蛋白质谱带数愈少，但本文未能找到特异诱导蛋白；一般认为铁过量情况下ROS产生加强，本文结果显示即便在铁缺失条件下，也有氧化胁迫伤害，而且缺铁越严重，活性氧伤害越大。

Secondly, enrichment of 13C and 15N and their combination with NMR spectroscopy can help us study not only the dynamics of decomposition of organic materials but also the changes of their chemical structures during the turnover of the organic materials, which can provide more information in clarifying the C and N cycling and humification of the organic materials applied to soils.

本文根据已收集到的部分资料，对13C标记技术在土壤和植物营养中的应用情况作一简要综述，并在此基础上讨论了13C加富标记技术在研究植物光合作用、光合产物的去向以及标记秸杆在土壤中的分解等方面的应用及其注意点，旨在能为国内开展这方面的工作提供十分有用的参考

The results were as the follows: maize inbreeds were sensitive to salt stress;different salinity stress had inhibition effects on the germination rate,shoot length,relative water content and net photosynthetic rate;different inbreed had obvious difference in salinity tolerance;the best one was XS98-28;the next was XSK5;the middle were in turn XSF,XS01-61;the lower were other inbreeds.

结果表明：玉米对盐胁迫非常敏感，不同盐浓度均对玉米芽苗期的发芽率、胚根长度、叶片相对含水量及净光合速率产生抑制作用；不同材料间耐盐性存在明显差异，各指标均能反映出不同材料的耐盐性；通过鉴定筛选，14个材料中，耐盐性极强的为XS98-28，耐盐性较强的为XSK5，耐盐性中等的为XSF，XS01-61，其余材料耐盐性均较弱。

Jack pine had higher rate of gas exchange and water use efficiency than black spruce when seedlings were well watered.

解除干旱胁迫后，黑云杉的气孔敏感性、光合能力及水分利用效率的恢复都要比北美短叶松更快。轻度的干旱胁迫锻炼可以帮助北美短叶松在更严重的干旱胁迫下保持固有而强劲的耐旱能力。

When we start a landscape design of expressway from Xichang to Panzhihua , the first, Dodonaea viscosa, Lantana camara, Jatropha curcascim were chosen, which had such characteristics as adapting reginonal climate, corresponding with purpose of restoration, and self-renewal, whose maintenance and investment were lower.

在进行西攀高速公路绿化景观设计时，优选出适合当地气候、符合恢复目标、在路域附近的植物群落具有自我更新能力、养护成本较低的植物有车桑子、五色梅、小桐子，它们能够与环境协同进化；由外地引进的树种如新银合欢、台湾相思经造林实践检验有更广泛的适应性，作为先锋树种是适宜的；从光合特性测定值比较五色梅、棕榈、加杨、香樟、赤桉、丝兰、石榴水分利用效率较高，其个体生态特性表现出较强的耐干旱能力。
