叶二形(不同的能育枝上的叶片在外形上在不育枝上的东西)；榕果梨形给多少球状，或圆筒状，3-5厘米直径 7 T 。

A SSR marker based linkage map covering chromosome 10 and the short arms of chromosomes 1 and 11 of rice was constructed and applied for mapping fertility-restoring genes in Zhenshan 97A/(Zhenshan 97B/Milyang 46)F_ 6 population consisting of 704 lines.

应用由704个株系组成的珍汕97A/(珍汕97B/密阳46)F6测交群体，针对水稻第10染色体和第1、11染色体短臂构建了微卫星标记连锁图谱，检测到控制野败型细胞质雄性不育育性恢复的4个QTL，其中位于第10染色体长臂中下部的Rf4具有主效效应，位于第1染色体短臂的Rf3具有较大效应，位于第10染色体长臂近着丝粒处的qRf10和第11染色体短臂近着丝粒处的qRf11表现出微效作用。

Methods "Beiao" bait and no "beiao" were selected to evaluate the feeding acceptability of SD rats in laboratory by select fooding method;after putting "beiao" in field for three and six monthes,the results for controlling rats by trap were recorded respectively;rats procreation and rate of infancy and manhood of catching rats from three fields("beiao" bait,Anti Cruor bait and naturalness) were analized by anatomised.

方法实验室采用常规毒饵适口性实验方法观察适口性，现场选择在农田、农户环境，于4次投放毒饵后检查鼠类对贝奥雄性不育剂的消耗水平，用贝奥雄性不育剂处理后3个月和6个月测定鼠密度，解剖观察成年鼠生殖能力，测量成幼年鼠的比例。

The results indicated that more Ca〓 in sterile anthers might be related with its abnormality of function.

由此看出不育系花药维管束中有较多的Ca〓与其结构功能的失常及雄性不育性产生有一定关系。

The effect of a certain CMS cytoplasm on different characters of F_1 is dissimilar and different CMS cytoplasms have vary effects on a same character.Most of CMS cytoplasms present negative effects.

同一种不育细胞质对不同性状的效应是不同的；不同的不育细胞质对同一性状的效应也存在着差异；且对大多数性状表现为负向效应。

In this paper, the relationship between characteristics of glume-gaping grains and lodicules was studied to ascertain the reason of glume-gaping grains lines on CMS lines.

研究水稻细胞质雄性不育系种子裂颖特性与浆片的关系，揭示不育系种子裂颖的内在原因。

The pectin esterase gene and amino acid permease gene abundantly expressed in floral buds of NCa CMS while pectin esterase gene showed no transcript either in young leaves of NCa CMS or in the two tissues of maintainer line, and amino acid permease gene slightly expressed in the corresponding tissues.

结果表明，果胶甲酯酶基因和氨基酸通透酶基因都在不育系花蕾中大量表达，果胶甲酯酶基因在不育系叶片、保持系的花蕾、叶片中都没有检测到；而氨基酸通透酶基因有微量表达。

Previous studies have established that the sterility of Nongken 58S is controlled by one or two loci, depending on the genetic backgrounds of the material used in the crosses, and the locus located on rice chromosome 12 designated pms3 is the one at which the original...

此前的研究发现，根据杂交组合中材料遗传背景的不同，农垦58S的不育性受到1个或2个位点的控制，位于第12染色体上的pms3位点是导致正常水稻品种农垦58突变为光敏雄性不育水稻农垦58S的根源。

In addition, there have no enough studies in the mechanism of spermatogenesis arrest induced by heat, and also there are many negative effects in the male contraceptive methods during these years like surgical ligation of vas deferens. All these factors have brings researchers to found a safety and efficacy methods for the problems in male reproduction.

因此，本研究通过高温处理未成年动物的模型，从细胞及分子水平探讨高温作用后生精功能障碍的机理，并对高温引起不育的机制进行深入研究；这些研究对阻止、延缓或减弱上述因素对人类生育能力的损害有重要意义，同时也为临床治疗一些男性不育、指导未成年男性生殖保健和探索男性避孕措施的研究提供理论基础。

In the near future follow-up,there are no complications like adhesions of spermatic cord and infertility.

近期随访中，未发现精索粘连及不育等并发症，有待于长期各科合作的随访，国外已有聚丙烯补片引起不育的报道，应引起临床的高度重视。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
