From the south wind that breathed a century and a half over the green wheat; from the perfume of the growing grasses waving over heavy-laden clover and laughing veronica, hiding the green-finches, baffling the bee; from rose-lined hedge, woodbine, and cornflower, azure blue, where yellowing wheat stalks crowd up under the shadow of green firs.

它来自一个半世纪以来吹过青麦的南风；来自那些摇曳在重甸甸的金花菜和欢笑的威灵仙上头而藏匿山雀驱逐蜜蜂的渐长的草的香气；来自蔷薇罗布的篱笆，金银花，以及青杉荫下转黄麦茎丛中天蓝色的矢车菊。

It employs carbon dioxide as carbon source to replace traditional sugar, the concentration is controlled to be 2000- 3000ppm, takes light transmission, ventilating and water- proof fluoroethylene resin film as container, and gets tissue culture sprout and replanting sprout of chrysanthemum, which are characterized by largest plant height, largest leaf number, root number, longest root length and largest dry net weight of haulm and root, high rate of emergence and little pollution rate.

本发明提供了一种无糖培养菊花的方法，采用二氧化碳作为碳源，替代传统的糖，控制释放浓度为2000～3000ppm，采用透光性好、透气不透水的氟乙烯树脂膜为容器，在此种培养条件下，不同品种的菊花组培苗和组培后移栽苗在株高、叶数、根数、最大根长、茎叶部分和根部部分的干鲜重最大，出苗率高，污染率最低。

The above three soybean varieties were treated with short-day of 12 h and long-day of 16 h in whole growth period, the different photoperiod treatments changed development process, podding-habits, plant morphogeny, and agronomical characters of different types of stem termination. And by this method photoperiod-sensitive and photoperiod-insensitive soybeans were divided, which is an important meaning at the production and popularization of soybean varieties.

对以上三个不同结荚习性品种进行两种较为极端的全生育期光照处理，短日照处理(12小时)和长日照处理(16小时)均可不同程度地影响不同茎顶类型品种的生育进程、结荚习性、株型和其他农艺性状，并且以此方法可区分出光敏感性相对较强和较弱的品种，对品种的生产和推广有一定的指导意义。

The main results were as follows:An appropriate concentration of ethephon sprayed on leaves of peanut made stems and branchs height shorter,but more branches;The fresh weight and dry weight per unit of leaf area and per plant increased;It optimized some physiological and biochemical characteristics in the leaves.It was showed that the ethephon increased obviously the contents of protein and chlorophyll and the activity of SOD and POD in the leaves,and improved the rates of photosynthesis and transpiration of the leaves,and increased the activity of the roots,but decreased the content of MDA in the leaves;It improved the quantity of pods,the percentage of plumy pods and the peanut yield.

结果表明：喷施适宜浓度的乙烯利可使植株相对矮化，抑制花生地上部分的生长，使主茎和分枝长比对照短，但分枝数较多；提高单位叶面积鲜重、干重以及植株鲜重、干重；优化花生植株的生理生化特性，表现为显著提高了花生叶片的蛋白质含量和叶绿素含量及SOD和POD活性，增强了花生叶片的光合速率和蒸腾速率，增强了主根活力，降低了花生叶片的丙二醛和可溶性糖含量；提高植株的单株结荚数、饱果率和产量。

From differentiation of soybean varieties and photoperiod adjustment, anatomical differentiation essence of different types of stem termination soybean varieties, variation law of stem termination development under different photoperiod treatments, effect of long day on the terminal raceme of soybean, regulation rules of AGAMOUS gene among different soybean varieties and under different photoperiod treatments were studied, which would provide theory base of plant type breeding of soybean especially improvement of podding-habits and cultivation and management of soybean.

因此，试验于2006和2007年在中国农业科学院作物科学研究所完成，主要从大豆的品种差异和光周期调控入手，利用解剖学和分子生物学技术，研究不同结荚习性大豆品种的本质差异、大豆在不同光周期处理下茎顶的变化规律，进一步明确长日照对大豆顶端花序的影响，及AGAMOUS基因在不同光周期处理下大豆品种中的表达规律，为大豆株型育种特别是结荚习性的改良及大豆栽培管理提供理论依据。
