The treatment increasing femaleness madethe formation of 1st female flower earlier by making the appearance of thepear value of endogenous GA3 content earlier while the treatment increasingmaleness made the GA3 content drop at first,then pick up gradually.

植株进入开花盛期后，如在苗龄50天到70天这一时期，植株雌花数的增加量及♀/♂比值的变化幅度则和茎尖内源IAA和ZT的含量的变化幅度有关，这一段时间内，茎尖内源IAA含量下降越少，ZT含量下降越多，则雌花数增加越多。

In this research, we have studied the effects of a series of factors (genotypes, basicmedia, plant growth regulators, explants, inoculation methods, leaf ages and darkperiod) in the inducing adventitious shoot of strawberry(Fragaria ananassa Duchcv.

本试验以草莓品种&丰香&和&章姬&为试材，研究了草莓离体再生过程中基因型、基本培养基、植物生长调节剂配比、不同外植体、接种方式、苗龄和暗处理对草莓离体再生不定芽的影响，获得了草莓高效的离体再生体系。

In this research, the pubertal five-week-old SD rats were chose as experimental object to establish the animal model for simulating maxillary protraction, on which was imposed the orthopedic force of 85g with utilizing the self-devised maxillary protraction appliance. Located lateral X-ray cephalograms were taken to measure and analyze the changes of maxillary development after exerting the orthopedic force for 4 weeks. The technique of immunohistochemistry was used to investigate theexpression of TGF-, in frontomaxillary sutures and palatomaxillary sutures with identical force performing for different extent of time. The average hue was selected as indicator, which was measured by the means of the analysis system of pathological color images. The measuring data were analyzed by the one-way ANOVA in software SPSS 11.0 version.

本研究采用自行设计的上颌前牵引装置，以生长发育期5周龄SD大鼠为实验对象，施加85g的矫形力，建立了模拟上颌前牵引的动物模型，通过X线头影测量分析，观察施力4周后上颌骨的生长发育情况；应用免疫组织化学技术，检测同一力值作用不同时段下TGF-β_1在上颌骨的额颌缝、腭颌缝的表达，彩色病理图象分析系统测定每张切片中阳性染色细胞的平均灰度值，结果采用SPSS 11.0进行方差分析。
