In 'Huanong Bendizao',notable peaks were found for IAA in the seed,rind and pulp and seed ABA at the stage of fruit enlargement,GA1/3 and ZR concentrations in the seed were relatively high and significantly increased during fruitlet growth and early fruit enlargement, whereas the levels of four endogenous hormones in the rind and pulp were relatively low and changed a little as time passed.

2华农本地早种子、果皮和果肉IAA及其种子ABA含量均在果实膨大期内出现明显峰值，在幼果阶段至果实膨大初期内种子GA1/3和ZR含量均居较高并出现明显上升，对应的果皮、果肉4种内源激素水平均相对较低且变幅小。

Investigation of DNA replication levels in primed seeds with flow cytometric determination showed that the 6C:3C ratio in embryonic root tip cells was higher than the unprimed seeds at all stages of seed imbibition.

The seeds of Achyranthes Bidentata from recoverable satellite were researched in the present study. The developing progress of the seeds, which were of the SP 1 from the seeds carried by satellite, was observed and analyzed, comparing with the control. Furthermore, the germinative indexes of the seeds from HT and CK were also observed.

利用返回式卫星搭载的中药牛膝种子为材料，与对照组牛膝种子相比较，对搭载后的牛膝种子SP 1植株的种子生长发育过程进行了观测和分析，并对SP 1植株获得的种子发芽及生长情况进行了进一步的观测。

In order to verify the possibility of lyophilization technology used for the drying treatment of wheat seed, different drying modes under lyophilizing, vacuuming and hot air was employed and compared in this research.

为了探索真空冷冻干燥技术用于小麦种子干燥处理的可能性，采用真空冷冻干燥、真空干燥和热风干燥 3种方式对小麦种子进行干燥处理，在不同环境温度和压力下，研究种子中温度-时间分布曲线，并通过分析复水率、出芽率和幼苗生长情况进一步研究了这 3种干燥方法对小麦种子生物活性的影响。

In order to explain clearly the variation status of embryo from tetrapoid Robinia pseudoacacia and fully use the variation resource initiated in the sexual reproduction of TRP in the further improvement of TRP, the classification and vitalities of seed embryos from tetraploid Robinia pseudoacacia were studied. The main results are as follow. According to the cotyledon number, color and plumpness, the seed embryos of TRP could be divided into 5 types: YVT (yellow, very replete,2 cotyledons), YMT( yellow, more replete,3 cotyledons ), YRF ( yellow, replete,4 cotyledons ), GNT ( green, no-replete, 2 cotyledons ) and WNT ( white, no-replete, 2 cotyledons ).

为了阐明刺槐同源四倍体种子胚变异状况及充分利用刺槐同源四倍体有性过程创造的变异资源对四倍体刺槐进行遗传改良，研究了刺槐同源四倍体种子胚类型及其生活力特征，主要结论如下：刺槐同源四倍体种子胚按照子叶数量、颜色及饱满程度，可以划分出5个类型：黄二、黄三、黄四、绿二及白二，所有类型种子胚混合平均单胚重量接近二倍体的1/2。

Because manual seed points are not exactly located on the crack features, two methods are proposed to search the geometric crack features, such as crotches. Wavelet transformation, clumpping, thinning and crossing algorithm are processed sequentialy to reach the semi-automatic feature extraciton purpose. Depending on these seed points, crack tracks and edges are determined by the method in this paper. Local image registration is utilized to raise relative accuracy and acquire the expansion of concrete cracks.

由於人工种子点并非准确落在特徵点，因此在种子点座落区域取目标视窗，使用基底函数转换边界侦测、区域增长消除杂讯区块、裂缝区块骨骼细化，接著寻找裂缝交叉点及端点，准确寻找出种子点应座落的位置，以此位置匹配后时期裂缝影像种子点，续以侦测前后时期裂缝边界，利用局部套合求得高相对精度，求得裂缝成长的情况。

4The low similarities betweenseed banks and the established vegetation were considered to be the consequences ofthe frequent presence in the established vegetation but not in seed banks of someperennial rhizomatous plants which mainly depended on vegetative propagation toregenerate;insignificant difference in the species composition of seed barks amongtransects, might be accounted for by the fact that the flood drift had functioned as adisseminator for propagules;and with the intensifying of the flooding disturbance,both species diversity and the similarity between seed banks and establishedvegetations declined.

4种子库与地上植被相似性普遍较低，其原因是主要靠营养繁殖以更新种群的多年生根茎植物经常在植被中出现而不在种子库中出现；受水淹干扰的样带之间种子库的种类组成差异不大，说明洪水漂移行使了繁殖体传播和散布的功能；随水淹干扰强度增加，种子库物种多样性指数减小，种子库与地上植被的物种组成相似性下降。

The factors influenced the seed vigor are introduced. The seed treatment technology for maintaining and improving seed vigor are summarized.

介绍了影响种子活力的因素，从种子形成、发育成熟、贮藏和播前预处理过程，综述了保持和提高种子活力的种子处理技术。

The seed purity of more than one hundred and thirty samples of six maizevarieties was assayed by using the three testing methods: storage proteins electrophoresis,isozyme isoelectric focusing in acrylamide and examination at field plots. Some importantpoints can be concluded from analyses as spearman order rank correlation on the seedpurity data as follows:First, there were deviations of the real performances to those purities obtained from out or in laboratory testing, even from the examination at field plot that is a routine way. Second, the seed globulin and isozyme electrophoresis, both with characteristics of rapid, cost-effective, devoid of environmental effect and speed, showed consistent purity; while the field-testing gave a higher degree of purity on the high side of cost than that in-lab approaches. Third, a good consistent purity was observed in the field plot and seed globulin testing, whereas inconsistency between field-testing and isozyme process. The last point is that seed globulin electrophoresis be a practical method apt to seed purity testing for maize.

并对130多份样品用三种检验方法(盐溶蛋白电泳、同功酶等电聚焦电泳和田间小区)检测的种子纯度数据作排序相关等统计分析，得到如下结果：室内外检测方法都会与种子真实状况有一定差异，田间种植鉴定与真实情况符合性并不一定最好；盐溶蛋白与同功酶等电聚焦这两种方法检测种子纯度所需时间短，成本低，不受外界环境限制，出结果快，二者的结果没有太大差异；田间种植鉴定成本较高，检测的结果普遍偏高；等电聚焦电泳与田间鉴定的一致性年度间存在差异，而盐溶蛋白凝胶电泳法与田间鉴定的一致性较高；种子盐溶蛋白凝胶电泳法较适于鉴定玉米种子纯度。
