The basic characteristics of the whole process were gained. When the seedling falling out of the tube feet, the difference of the time interval between 2 neighboring seedlings wasn't notable, and the difference of the time interval of 2 neighboring seedlings wasn't notable and the agricultural time was not special notable. These results showed that the uniformity of the pneumatic ordered throwing transplantation was excellent and could meet the demands from design and agriculture; Upstanding state was primary as the seedling falling out of the tube feet, it showed that the seedling could keep erective preferably when the seedling falling to the field.

结果表明：钵体苗从导苗管管脚中落出时，相邻2株钵体苗落出时的时间间隔差异不显著，从左中右3个管脚落山的相邻2株钵体苗的时间间隔与农艺要求的时间差异极不显著，说明气力有序抛秧均匀性好，能满足设计要求和农艺要求；钵体苗从导苗管管脚落出时以直立状态为主，表明气力有序抛秧的钵体苗落入田间时能较好地保持直立。

Suitable control content of culture medium can benefit growth, proliferation rate of Williams B6 seedling, save spending of production material. The content of 30ml per bottle show the highest proliferation rate and the higher usage of culture medium, the contrary result will appear when preponderate over the content of 30ml per bottle, but the increase weight of single seedling. For the losing of medium by sterilization, seedling SO2 resistance and other effects, it's considered the content of 25~30ml per bottle is fit for production of tissue culture seedling.

适宜控制培养基用量，能稳定威廉斯B6香蕉组培苗生长量、繁殖率，减少原料投入。30ml的用量其增殖率最高、培养基利用率较高，超过30ml的用量其增殖率相对下降，培养基利用率降低，但单苗增重量最大，综合考虑培养基损失、蕉苗耐SO2性等因素，认为培养基用量应控制在25~30ml/瓶。

Water stress is one of the most important abiological stress to maize seedling .In this study, we arm to identify the sensitive stage of maize seedling to water stress and select the material which tolerance to flooding. And we use waterlogging tolerance index to identify the sensitive stage of maize seedling. we have studied 20 inbred lines of maize which seedlings under water stress in three stage. The result show that the three leave stage is the most obvious stage to flood stress. In addition, we have analyzed ten of the inbred lines to re-act the waterlogging tolerance index. The result show good re-action. And the result also show that waterlogging tolerance index is a credible index to select waterlogging tolerance materials in seedling.

涝渍是玉米苗期主要的非生物逆境胁迫之一；本试验通过对20份玉米自交系进行苗期的淹水对照试验，采用了三个处理时期，并利用耐渍系数作为指标进行敏感时期的鉴定，结果表明三叶一心期是淹水的相对最佳时期；同时利用其中10份自交系对耐渍系数的重演性进行了分析，结果表明其重演性很好；同时结果还表明耐渍系数是耐渍性鉴定的一个可靠指标。

When the Agropyron seeds were treated with 1.0kv.cm-1,the seedling rate,seedling length and root length increase by 4.5%,81% and 48% respectively,and treated with 4.5kv.cm-1,the seedling rate,seedling length and root length increase by 4.8%,84% and 66% respectively.

结果表明：不同电场对冰草种子萌发及幼苗生长产生不同的影响，用1.0 kv/cm电场强度处理冰草种子10 min，可提高种子出苗率4.5%，苗长增长81%，根长增长48%；用4.5 kv/cm电场强度处理冰草种子10 min，可提高种子出苗率4.8%，苗长增长84%，根长增长66%。

Heddewigii, Dianthus barbatus L, Dianthus latifolius, Dianthus caryophyllus and Dianthus chinensis var. liaotungensis, with relatively high fructification rates and certain traffic tolerance, showed little difference in ecological adaptability and exhibited an average seedling height of 20cm and a mean crown size of 23cm, and pruning during the late growth period could obviously promote flowering and reduce the seedling height by 3cm. While Dianthus barbatus L. and Dianthus phlox subulata, with relatively low fructification rates and higher traffic tolerance, had an unobvious difference in ecological adaptability, which present an average seedling height of 14cm and a mean crown size of 36cm, and pruning during the late growth period could promote flowering to some extent and reduce the seedling height by 2cm.

其中，大红石竹、锦团石竹、五彩石竹、五寸石竹、浓香石竹、重瓣石竹品种间差异小，平均苗高20cm，冠幅23cm，结实率相对高，有一定耐践踏能力，在生长后期进行修剪能很好的促进开花并降低株高3cm；常夏石竹和美国地被石竹品种间差异小，平均苗高14cm，冠幅36cm，结实率低，耐践踏能力稍强，在生长后期进行修剪能较好地促进开花并降低株高2cm。

This paper introduced some practical Dendrocalamus latiflorus clonal propagational seedling raising techniques including bamboo branch cutting seedling raising,seedling raising with planted internodes,and plant division seedling raising to meet the constantly expanding need of D.

为解决大面积造林竹苗缺乏的难题，本文从实际出发介绍了几种切实可行的麻竹无性繁殖育苗技术：竹枝扦插育苗、埋节育苗和分株育苗，用以满足不断扩大的麻竹造林的需要。

The grain-leaf ratio showed a periodic oscillation relation to total seedling number in each growing stage, it was decreased with the increasing of total seedling number in earlier winter stage, wintering stage and jointing stage and was increased with the increasing of total seedling number in turning green stage. The grain-leaf ratio was bigger when the total seedling number was 2700000-3200000 plants/hm^2 in earlier winter stage and was 6400000-8200000 plants/hm^2 in turning green stage.

粒叶比与各生育阶段总苗数呈周期性振荡关系，且随着冬前期、越冬期和拔节期总苗数的增加而减小，随着返青期总苗数的增加而增大，当冬前期总苗数在270万320万株／hm^2、返青期总苗数在640万820万株／hm^2时，粒叶比较高。

After seedling trees of Yunhe Snow Pear were polluted by Pb(superscript 2+), Cd(superscript 2+), synthesis of chlorophyll was restrained, toxic effect of Pb(superscript 2+), Cd(superscript 2+) on seedling trees was intensified, membrane lipid peroxidation damage was increased. And the protective enzymes system start-up of polluted seedling trees enhanced antioxidative enzymes activities of seedling trees.
