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。

Healthy spikes of high-resistant varieties had thicker cell wall and tissue of cortical sclerenchyma, more number of cortical sclerenchyma layers, more number of fibrovascular bundles, smaller area of green subcutaneous tissue in rachis, and theses differences, except number of fibrovascular bundles, enlarged over time. Considering inoculated spikes, cell wall and tissue layers of cortical sclerenchyma displayed different, and to how much extent the relationship between this difference and anti-extension ability of variety had not determined. 6. On the analysis of agronomical characters and molecular marking technology, more than 30 alien anti-Gibberella wheat materials and two mutants coming from this experiment were evaluated their hereditary multiplicity.

实验结果还证明，高抗品种和感病品种的穗轴组织结构确实存在一定差异，在健康穗中，主要表现在高抗品种的皮层厚壁细胞壁和皮层厚壁组织较厚，皮层厚壁细胞层数较多，维管束数目较多，穗轴表皮下绿色组织面积较小，抗、感品种间的差异达显著水平，随发育时间延长，高抗品种的皮层厚壁细胞壁厚度、厚壁组织厚度和厚壁细胞层数增加的幅度较大；在病穗中，主要表现在高抗品种的皮层厚壁组织细胞层数和厚壁细胞壁厚度增加的幅度较大。

As the coach rolls swiftly past the fields and orchards which skirt the road,groups of women and children,piling the fruit in sieves,or gathering the scattered ears of corn,pause for an instant from their labour,and shading the sunburnt face with a still browner hand,gaze upon the passengers with curious eyes,while some stout urchin,too small to work but too mischievous to be left at home,scrambles over the side of the basket in which he has been deposited for security,and kicks and screams with delight.

货车飞快地穿过田野的时候，可以看到路边的果园，一群群妇女和儿童正把水果堆在筛子里，把分散的一穗穗玉米集到一起，劳动会儿又歇歇，用一双更黑的手擦擦被太阳焦灼的脸，用好奇的眼光打量着路人，几个健壮的顽童，太小了不能做事，而又因为太调皮不能留在家里，爬过已经防范好的篮子边缘，兴高采烈地踢着尖叫着。

For the approach to the relations between the endangered situation and their sexual reproductive processes in Cimicifuga nanchuanensis, some comparative studies were made in C.simplex , a close and widespread species.

Result Richards Model and Monodic Quadratic Equation could properly describe grain dry matter growing process and the change process of grain filling rate with days after anthesis. There was big difference in average grain filling rate, maximum grain filling rate under different planting density. Average grain filling rate 1.26 mg/ and maximum grain filling rate 2.44 mg/ of T7 were the quickest, and the average grain filling rate 0.94 mg/ and maximum grain filling rate 1.99 mg/ of T12 were the slowest, and the maximum difference percentage of the average grain filling rate and maximum grain filling rate among different density were 33.98%, 22.61%. There was significant correlation between average grain filling rate, maximum grain filling rate, grain filling active duration, rapid increasing stage and thousand grain weight, and the correlation coefficients were 0.628*, 0.630*, 0.849**, 0.739**. Active grain filling duration contributed mostly to TGW.

结果不同密度处理间千粒重、单位面积穗数、穗粒数、单株穗数、单位面积籽粒产量均存在显著差异；不同密度处理冬小麦的籽粒灌浆均符合慢－快－慢的&S&型生长特性，用Richards模型能很好地模拟冬小麦籽粒增重过程，用一元二次抛物线方程能较好地模拟冬小麦灌浆速率随花后时间变化过程；不同密度处理间平均灌浆速率、最大灌浆速率有较大差异，最大差异率分别为33.98%、22.61%，T7的平均灌浆速率1.26mg/及最大灌浆速率2.44mg/均最大，T12的平均灌浆速率0.94mg/及最大灌浆速率1.99mg/均最小；平均灌浆速率、最大灌浆速率、灌浆活跃期、灌浆快增期与千粒重显著或极显著正相关，相关系数分别为0.628*、0.630*、0.849**、0.739**；通径分析表明，灌浆活跃期对千粒重的贡献最大。

As compared with the traditional irrigation-traditional fertilization, the following results of the improved traditional irrigation-optimized fertilization were obtained: reduced tiller number per unit area, lower percentage of the tiller ear number/the tiller number, the decreased ear number per unit area, the greatly reduced grain number per ear (1999-2000) and like weight of 1, 000 grains; almost the same plant height; shorter base internode length, a bit more weight per unit internode length, longer internode length under ear; lower LAI values in middle and later stages; coincident process of dry matter accumulation from straight growth onwards, a little more dry matter accumulation amount from earing to maturity; shorter and thicker flag leaf, 2〓 leaf, 3〓 leaf and 4〓 leaf from top, reduced total area of these leave; bigger mean canopy leaf tilt angle, smaller light extinction coefficient , higher ratio of light penetration in the upper, middle and lower parts of the wheat canopy, and tighter plant type; almost identical dynamic change of flag leaf chlorophyll content; and almost the same root amount in 0-120cm soil layer, smaller rate of progressive decrease of the root length density and root weight density with soil getting deep and relatively increased root amount in deeper soil layers.

在传统灌溉-优化施肥条件下，冬小麦单位面积总分蘖数比传统水肥减少，成穗率降低，单位面积穗数有所减少，穗粒数、千粒重无显著性差异；株高基本无变化；基部节间长度缩短，充实度略微增高，穗下节间增长；中后期叶面积指数略低于传统水肥；起身至成熟干物质积累量动态变化过程与传统水肥十分接近，但抽穗至成熟形成的干物质量增加；旗叶、倒2叶倒3叶、倒4叶叶长及总叶面积有所减少，叶片相对增厚；冠层平均叶倾角大，消光系数小，冠层各层的透光率较高，株型紧凑；旗叶叶绿素含量动态变化与传统水肥十分接近；0-120cm土层总根量与传统水肥也差异不大，但根长密度和根重密度随土层深度递减速度较慢，根系在下层土壤的分布相对增多。
