A synthetic hexaploidy wheat with resistant to preharvest sprout and hard glume was employed to cross with a common wheat line with character of susceptible to preharvest sprout and normal glume hardness, and then built up the F3 population, aiming at studying the relationship between the resistance to preharvest sprout and its glume hardness.

Furthermore, each developmental phase showed several different phases, these included inflorescence 0 phase, inflorescence Ⅰ phase, inflorescence Ⅱ phase; spikelet Ⅰ phase, spikelet Ⅱ phase, spikelet Ⅲ phase; palea primordium phase, lodicule primordium phase, stamen primordium phase and carpel primordium phase.

在这3个大的发育时期，又根据每一发育时期中的原基分生组织生长发育的程度及先后顺序分别又可分为：花序0期、花序1期、花序Ⅱ期；小穗期Ⅰ期、小穗Ⅱ期、小穗Ⅲ期；内稃原基分化期、浆片原基分化期、雄蕊原基分化期、心皮原基分化期。

The dynamic changes of physiological and biochemical indexes of healthy spikes and inoculation ones of the resistant mutants indicated that PAL activity and content and changing tendency of total phenolate and flavoniods and MDA in the healthy spikes of the mutants were similar to that of their susceptible donors, whereas, for the inoculated spikes, content and changing range of these indexes existed significant difference between two kinds of strains, changing from high-resistant variety (Sumai3 ) to their susceptible donors.

以典型抗扩展品种和突变体供体亲本为抗、感对照，对抗赤霉突变体的健康穗及接种穗的生理生化特性研究结果显示，在健康穗中，抗性突变体的PAL活性、总酚、类黄酮及MDA含量及变化趋势与其感病亲本相一致，但在病原菌侵染后，这些生理生化物质的含量与变化程度与其亲本有了明显的差异，其变化范围介于典型高抗品种和感病亲本之间，变化趋势与亲本或抗性品种一致。

YaJin-2: 155-day growth period in Beijing ,4 to 5 meters high, tight ear, ear length of 28cm, weight of 21g and grain weight of more than 60g; Brix between 18% and 23%, stem juice rate of 67%, per-mu grain yield of 350kg and per-mu stalk yield of 5000kg; Resistant to insect and pets, anti-anthrax, mildew and red stalk rot.

雅津2号甜高粱，北京生育期155天左右，植高4~5米，中紧穗，穗长28厘米，千粒重21克。穗粒重60克以上。汁液锤度18－23%，茎秆出汁率67％，平均亩产籽粒350kg 。亩产茎秆5000kg 左右。对病害有较好的抗性，抗炭疽病、霜霉病和秆红腐病。

The result indicates that the main influence factor on rootage of Photinia serrulata was hormones kind,and the next came cuttings types and cutting substrates.Hormone concentration had the least influence on cutting rootage.

结果表明：影响红叶石楠插穗生根的主导因素是激素种类，其次是插穗类型和扦插基质，激素质量浓度的影响最小；激素IBA处理的插穗生根率极显著(α=0.01)优于NAA和GRR，绿枝中部和上部插条生根率极显著(α=0.01)优于下部，扦插在基质A1和A2更易生根。

The distribution of vascular bundle in the rachises of spikelet in different parts of ear had difference,and the number and area of

穗中不同部位小穗的穗轴中的维管束分布有差异；同一小穗中通向各小花的维管束数目和面积也不同。

There were on unique different protein observed in flag leaf at different development stage; but unique different protein were found in young spike at uninucleate microspore stage and non-1B/ 1R type male sterile lines lack a 17kD polypeptide compared with maintainers; at binucleate microspore stage and non-1B/ 1R type male sterile lines increase 17kD polypeptide compared with maintainers.

利用SDS-PAGE凝胶电泳技术对采用丙酮沉淀法提取的K型，C49S型和YS型小麦不育系和保持系旗叶小穗发育的单核期和二核期中的可溶性蛋白进行比较后发现，非1B/1R类K型不育系732A在小穗发育的单核期比同时期相应保持系732B少1条分子量为17kD的多肽，在小穗发育的二核期比同时期相应保持系732B多1条分子量为17kD的多肽。

As to Z1, longjiao 91060-2 and Balilla, the curature of panicle neck is significantly positively correlated with height, and the panicle type gene may link with height.

对Z1、龙交91060—2和巴利拉型直立穗型品种来说，颈穗弯曲度与株高呈显著或极显著的正相关，但穗型基因与株高基因可能是连锁关系而不是同一基因。

Significant differences in cytosine methylation level among the three tissues and the same changing tendency in two inbred lines were detected. Both MSAP (methylation sensitive amplification polymorphism) ratio and full methylation level were the highest in bracteal leaf, and the lowest in tassel.

结果表明，3个组织甲基化水平存在一定差异，并在两自交系中表现出相同的变化趋势，即雌穗苞叶的甲基化敏感扩增多态性比率和全甲基化率最高，穗位叶次之，雄穗最低。

Path analysis showed that N translocation rate of culm was higher for the high fresh ear yield varieties,while the N translocation rate of culm and tassel was higher for the high fresh kernel yield varieties,and the N translocation rate of leaf,bracteal leaf and ear axis was higher for the high kernel yield varieties.In addition,higher N translocation rate of leaf had a beneficial effect on N utilization efficiency as for fresh ear,fresh kernel or maturity kernel of the produce of waxy corn.

通径分析表明，鲜穗高产品种茎秆的氮素转移率较高，鲜子粒高产品种茎秆和雄穗的氮素转移率较高，成熟子粒高产品种叶片、苞叶及穗轴的氮素转移率均较高；叶片的氮素转移率高有利于品种鲜穗、鲜子粒及成熟子粒氮素利用效率的提高。
