The results showed that plant height increasing speed was significantly slow at the former and middle stage when K level was above 180 kg/hm2.On the contrary,the height of case-hardened plant improved markedly.When the K level was above 135 kg/hm2,the stem girth and maximal leaf area differed significantly as compared with CK,so did LAI.Yield and product value per unit area took the first place when 180 kg/hm2 potassium was used.Average price and proportion of middle and first grade tobacco leaf of 225 kg/hm2 potassium treatment were the highest as compared with other treatments and CK.Four economic characters of the two treatments differed at obvious significant level as companied with CK.The total sugar and K2O were increased,nicotine, total N,protein and Cl- were decreased with increased K levels.The potassium lacked symptom was alleviated with increased K levels,no symptoms was observed when 180 kg/hm2 potassium was used,the degree of weather infected fleck was decreased when the K levels was increased.

结果表明，在烟株生长前中期，当施钾量达到180 kg/hm2以上时，株高增长显著变慢，而定型株高则显著增高；茎围和最大叶的面积在施用135 kg/hm2以上的处理与CK之间的差异性达到极显著水平，叶面积指数也存在显著差异；单位面积产量和产值以施用180 kg/hm2的处理居首位，中上等烟比例和均价以施用225kg/hm2的处理最高，这两种处理的以上4个经济性状与CK之间存在极显著性差异；烟叶中的总糖和K2O含量随施钾量的增加而上升，烟碱、总氮、蛋白质和C-含量则下降；缺钾症状随施钾量增加而减轻，至施用180kg/hm2时已无缺钾症状；烟叶气候斑的发生程度也随施钾水平的提高而减轻。

Grass of willow leaf horsewhip belongs to herb of perennial of horsewhip female division, formal name: Verbena Bonariensis illustrious name: Purpletop Verbena, alias: Long bine horsewhip is South-American horsewhip grass, careless, originate in South America formerly of Brazil, Argentine and other places, the flower is cyme, small tubular flower is worn be born at spending cauline coping, open amaranth or lilac flower, along with spends a bine to consider individual plant tall to make an appointment with 100-150 centimeter, liu Xie is crossed opposite, the primary part of a historical period after sowing is elliptic brim somewhat notch, beautiful bine is smoked tall the Xie Zhuai after is the slightness leaf that be like willow shape the brim still has pointed notch, the bine is a square this a little bit very special, entire individual plant has cilium to feel the feeling that pricks thorn a bit, the meeting in ground of be out of office is cross of plant of fringy horsewhip female division with a few congeneric flowers, so often a few inflorescence upright among Yu Jusan and fringy model state plant appears.

柳叶马鞭草属于马鞭草科多年生草本植物，学名：Verbena bonariensis英名：purpletop verbena，别名：南美马鞭草。长茎马鞭草，原产于南美洲，花为聚伞花序，小筒状花着生于花茎顶部，开紫红色或淡紫色花，连同花茎算株高约100-150公分，柳叶为十字对生，播种后的初期叶为椭圆形边缘略有缺刻，花茎抽高后的叶转为细长型如柳叶状边缘仍有尖缺刻，茎为正方形这点十分非凡，全株都有纤毛摸起来有点刺刺的感觉，在野地里会与一些同属花为穗状的马鞭草科植物杂交，所以常有一些花序介于聚伞与穗状的中间型态植株出现。

The other is caused by plantyellow leaves, characterized by first of all, the lower part of the old leaves chlorotic plants, such as wheatperformancesmall, short narrow leaves, old leaves the lower part of the first yellow.

另一种是植物缺氮引起的叶片发黄，其特征首先是植株下部的老叶褪绿，如小麦缺氮表现为麦苗矮小，叶片短窄，下部老叶首先发黄。

In the seedlings time, the content of chlorophyll decreased by the deficiency of B, but the content of chlorophyll in the high efficiency cultivar decreased slowly than that of the low efficiency cultivar. This suggested that the leaves of the high efficiency cultivar can capture more light energy and the photosynthetic rate of the high efficiency cultivar decreased slowly. In the bolting time and blooming time, after two weeks of B deficiency treatment, the content of chlorophyll in the top leaves of the high efficiency cultivar decreased, and in the late time, the content of chlorophyll decreased slowly. But, the content of chlorophyll in the bellow leaves of the two cultivars had little changes. The reason may be that B in the high efficiency cultivar distributed to the propagative organ in the late growth, and the leaves were short of B.

苗期，缺硼导致甘蓝型油菜色素含量降低，且高效品种色素含量下降的幅度小于低效品种，表明营养生长阶段，同等程度的缺硼条件下，高效品种叶片对光能的收集能力以及光合速率下降的程度相对较小；苔期和花期，在两周的缺硼处理后，高效品种上部叶色素含量依然呈下降趋势，但随着生育期的推移，其下降幅度减小；而高效品种下部叶和低效品种叶片含量变化不大，可能是甘蓝型油菜进入生殖生长阶段后，高效品种将硼更多地分配到繁殖器官，而其叶片却承受了相对较大的缺硼胁迫。

The above facts indicated that silicon accumulation in the rice leaf sheath inside, the leaf surface and the sclerenchymatous cell, played the physical barrier role, delayed the hypha of sheath blight expansion.5、Analysing the physiological and biochemical mechanism of the resistance to rice sheath blight improved by silicon application in several respects.(1) After being inoculated with R.solani, O2 and POD activities disordered, CAT activities obviously declined. O2 producingvelocity in 91SP\'s leaves and leaf sheaths of Si+ rice plants were lower than those of Siriceplants, MDA content in leaves and leaf sheaths of Si+ rice plants were lower thanthose of Si- rice plants significantly in three days after inoculating, SOD、POD、CATactivities in leaf sheaths of Si+ rice plants were higher than those of Si- rice plantssignificantly in one day after inoculating, SOD、POD、CAT activities in leaves ofSi-treatment were higher than those of Si- rice plants significantly in three days afterinoculating. O2 producing velocity and MDA content in Lemont\'s leaves and leafsheaths of Si+ rice plants were lower than those of Si- rice plants significantly afterinoculating, and SOD、POD、CAT activities of Si+ rice plants were higher than those ofSi- rice plants significantly.

说明硅在水稻叶鞘内侧、叶表和厚壁细胞积累，起到了物理屏障的作用，延缓了纹枯病菌的扩展。5、阐明了施硅增强水稻抗纹枯病的生理生化机制(1)接种纹枯病菌后，两个水稻品种91SP和Lemont的叶鞘和叶片超氧阴离子自由基O2性紊乱，CAT活性明显下降；抗病品种91SP叶鞘和叶片施硅处理的O2产生速率小于缺硅处理，叶鞘和叶片MDA含量在接种第3 d后显著低于缺硅处理，叶鞘SOD、POD、CAT活性在接种1 d后一直显著高于缺硅处理，叶片SOD、POD、CAT活性在接种3 d后显著高于缺硅处理；感病品种Lemont叶鞘和叶片施硅处理的O2产生速率、MDA含量始终显著小于缺硅处理，SOD、POD、CAT活性始终显著大于缺硅处理。

The results showed that:(1) low N stress significantly decreased the leaf SPAD value, leaf nitrogen content, nitrate reductase activity and reduced distance between leaf-umbrella, leaf area. And these impact aggrandized as the stress intensity increased.(2) Responses to low-N stress were in different degrees between different varieties of rubber tree seedlings. On the whole, GT1 was most sensitive to stress, PR107 next, and RRIM600 was the least sensitive.(3) The SPAD value, DBL, LA were significantly positive correlated with LNC, NRA in the seedling leaves.

结果表明：（1）缺N胁迫明显降低了叶片SPAD值、叶片N含量和硝酸还原酶活性，缩小了叶蓬距、叶面积，且影响幅度随胁迫强度的加大而增大；（2）不同品种橡胶树实生苗对缺N胁迫的响应程度不同，总体上GT1较为敏感，PR107次之，RRIM600较不敏感；（3）橡胶树实生苗叶片SPAD值、叶蓬距、叶面积与叶片N含量、硝酸还原酶活性之间均呈显著或极显著正相关。

The seeds of Adzuki bean were irradiated by 60 Co γ ray of 0～700Gy.The results showed that:(1)The sub\|lethal dose(LD 50 )was 389Gy and the early seedling leaf at M\-1 showed incised,chlorotic,yellow,mosaicand curly edge.The absorbed dose was related with the rate of misshaped leaf.Chromosomal aberration, chromosome bridge and fragment of M\-1 in the tip were observed.If the seed was irradiated with 400Gy,the rate of abnormal cell at the root was more than 10%.The relationship between pollen fertility and irradiation dose was negative correlated.

本试验研究结果表明：60 Coγ射线辐照小豆种子的半致死剂量平均为 3 89Gy ，且M1生长初期叶片性状有明显的叶面缺刻、叶色缺绿、叶形不对称、叶缘卷曲、花叶、黄叶等致变现象，各种畸型叶出现频率与辐照剂量大小有关；M1根尖细胞中有多种染色体畸变类型，以染色体桥和断片频率较高，辐照剂量在 40 0Gy以上时根尖细胞异常率达 1 0 %以上；植株花粉育性与辐照剂量呈极显著负相关，京农 2号植株花粉育性达 5 0 %时的辐照剂量为 3 78Gy。

After 14D and 28D, Observe the color of the leaves,Count the number of leaves and respectively measure the seedling's height、root long、wet weight、dry weight、relatively water content、chlorophyll content、soluble sugar content、proteid content、nitrate reductase activity and Peroxide enzyme activity to discuss the effect of each element to the tomato seedling.

为材料，进行缺氮、缺磷、缺钾、缺铁的溶液培养，分别在培养14d和28d后观察其叶色，计算叶数并测定了各缺素植株的株高、根长、鲜重、干重、相对含水量、叶绿素含量、可溶性糖含量、蛋白质含量、硝酸还原酶活性和过氧化物酶活性。
