Purpuraristatus, the growth, fertility, chromosome configuration, EST isozyme etc. were analyzed in this paper. The results showed that the growth potentiality of (E. sibiricus×E. purpuraristatus) F2 and (E. purpuraristatus×E. sibiricus) F1 were much stronger than their parents, the plant height of the former was 143.2 cm. The whole plant was reseda, the latter was 129.7 cm. The spike nodding of two hybrids were in the middle of their parents, the anther was yellow; the pollen fertility was 0.02%~0.03%, seed set was 0; the average chromosome configuration of former pollen mother cell at PMC M Ⅰ was 6.90Ⅰ+14. 02Ⅱ, the latter was 7.82Ⅰ+13.59 Ⅱ, and lagging chromosome and bridge fragment were observed at meiosis anaphase Ⅰ the EST of the two hybrids F1 and their parents at tillering stage was some certain different in locus, number and intensity.

结果表明，正交F1和反交F1植株的生长势均很强，正交F1株高143.2 cm、全株浅绿色，反交F1株高129.7 cm、全株灰绿色；正、反交F1的穗型均呈双亲中间型，花药呈黄色，花粉可育率0.02%~0.03%，结实率为0，说明杂种高度不育；正交F1的花粉母细胞减数分裂中期Ⅰ平均染色体构型为6.90Ⅰ+14.02Ⅱ，反交F1为7.82Ⅰ+13.59Ⅱ，减数分裂后期丁有落后染色体和染色体桥等不规则现象；亲本及其正、反交杂种F1分某期幼叶的EST同工酶酶带的位点、数目和强弱均存在一定差异，可作为亲本及杂种在蛋白质水平识别的重要依据。

In succession, the middle layer of anther wall had the strongest Ca^2＋ fluorescence intensity, and the tapetum took second place during the meiosis of microspore mother cell.

小孢子内Ca^2＋分布不均匀，细胞质中的Ca^2＋荧光较弱，细胞壁处Ca^2＋荧光较强，二细胞花粉时期，细胞呈现较强的Ca^2＋荧光。

Monosomic 3, monosomic 5, monosomic 10, trisomic 4 and trisomic 5 as experiment materials, their meiosis behavior of pollen mother cell, pollen characteristics, physiological and biochemical characteristics of anther, section observation of pollen development and the structure of embryo sac were studied, and the effects on the seed set and transmission rate were analyzed.

本文以大白菜同源四倍体小孢子培养产生的且已鉴定为3号单体、5号单体、10号单体、4号初级三体、5号初级三体的非整倍体株系及二倍体株系等为试材，对各材料的结籽率、雄配子传递率进行了统计，并对花粉母细胞减数分裂行为、花粉特性、花粉发育和胚囊结构以及花药生理生化特性等方面进行了观察研究，进而分析了其对大白菜单体n-1雄配子和三体n+1雄配子传递率的影响。

At time of 5mm length of alabatrum, the miosis in microsporecyte and the sex differentiation was found, thus in female flowers, pollen mother cell showed a abnormal meiose then the pollen cells gradually disintegrated, final, contabescence had taken, and in male flowers, the stamen normally developed.

在幼蕾长到5mm左右，即花粉母细胞开始减数分裂时，出现花性别的分化，雌花中雄蕊花粉母细胞不能进行正常减数分裂，进而花粉细胞逐步解体而导致雄蕊败育；雄花中雄蕊发育正常至性成熟。

One inclusion was formed within the exosporium and remained with the spore after mother cell lysis.

当芽胞形成细胞裂解后，一种晶体被释放出来，形成自由的伴胞晶体，另一种则始终和芽胞粘连在一起。

It can make the atrophied follicle recovered vital force gradually, stimulant and improve the activity hair mother cell , finally activate parent materials fissiparity continually and make hair regained in large number.

它可以使萎缩的毛囊恢复重要力量，逐步兴奋剂和改进活动的头发母细胞，最后激活母公司材料 fissiparity 不断，使头发重新大量。

The cause of hindering the gynospore formation was short of boronin chestnut orchard,which led to the poor pollination and a decrease ofendogenous GA1/3, iPAs level and an increase of endogenous ABA level in ovary,which restrained the mother cell division of gynospore.The low level ofendogenous GA1/3,iPAs contents and the increase of endogenous ABA contentcaused a serious lack of reducing sugar,starch,protein and potassium in ovary,which led to a cease of young embryo development.

其中，大孢子形成过程的停滞是由于栗园B素缺乏，致使授粉不良和子房内源GA1/3、iPAS等含量下降，ABA含量上升，从而抑制大孢子母细胞分裂；幼胚发育停滞则是由于子房内源GA1/3、iPAS等生长类激素的上升启动受阻，继续处于低水平，ABA上升，使子房中还原糖、淀粉、蛋白质和K素积累受阻，造成营养严重缺乏。
