Results showed that TDI induced toxic action on spermatogenic cell,while the chondriosome was its target within the length and concentrations.

结果表明：在本实验染毒时间和染毒剂量范围内，TD I对雄性的生殖毒性主要表现为对各级生精细胞均有一定的毒性作用，作用的靶点是细胞内的线粒体；TD I通过影响各种酶的活性，干扰了睾丸组织的有氧代谢和无氧供能，抑制了细胞对能量的利用，损伤了各级生精细胞，导致生精上皮不可逆的损害，从而造成了其对雄性生殖系统的损伤；TD I对雄性生殖细胞的核酸代谢以及DNA合成有一定影响。

Aldrin at concentrations higher than 40 μg/L decreased life expectancy at birth of F1 generation of the cladoceran, that at 20 μg/L and 80-640 μg/L decreased net reproduction rate, that at 320 and 640 μg/L shortened generation time, and that at all the concentrations decreased intrinsic rate of population increase. Aldrin at 160-640 μg/L shortened life expectancy at birth and generation time of F2 generation of the cladoceran, that at 160 and 640 μg/L decreased net reproduction rate, but that at all the concentrations except for 40 and 320 μg/L increased intrinsic rate of population increase.

浓度高于40μg/L的艾氏剂使多刺裸腹溞F1代的生命期望显著缩短，20μg/L和80~640μg/L的艾试剂使F1代的净生殖率显著降低，320μg/L和640μg/L的艾氏剂使F1代的世代时间显著缩短，所有浓度的艾试剂均使F1代的种群内禀增长率显著降低。160~640μg/L的艾氏剂使多刺裸腹溞F2代的生命期望和世代时间显著缩短，160μg/L和640μg/L的艾氏剂使F2代的净生殖率显著降低；除40和320μg/L外，所有浓度的艾试剂均显著提高了F2代的种群内禀增长率。

Embryonic germ cell lines were isolated and cloned from gonad,gonadal ridge,analogue or the surrounding tissues of 9.5～13.5 days postcoitum mouse fetuses.Primordial germ cells were co-cultured with mouse embryonic fibroblasts obtained from the same conceptus.

The rate procreation of Apodemus agrarius from three areas("beiao" bait、Anti Cruor bait and naturalness)was different from each other,which were 0、22.00%、27.78% respectively.

4抗生育药物处理后，对鼠类生殖功能有比较明显的影响，实验区、抗凝血杀鼠剂、自然对照区3组黑线姬鼠有生殖功能率分别达到0、22.00%、27.78%。

Objective: To study the effects of pentabrominated diphenyl ethers on the structure and function of reproductive system in rats and mechanism.

目的：研究五溴联苯醚对大鼠生殖系统结构和功能的影响及其机制方法：在五溴联苯醚对雄性大鼠生殖系统作用的时效关系研究中，选取健康23日龄雄性SD大鼠40只，体重40～60g，随机分为8组，每组5只，分别为染毒5、15、30、45d的实验组和溶剂对照组。

Since curly leaf hybrid could be recognized at early stage,and displayedobvious dwarfness,choosing"Zha′ai 76"as paternal parent not only raised thehybrid-selecting efficiency from the pollinated progenies,but also raised thebreeding efficiency of apomctc dwarf roostock of apple.

鉴别宽叶型杂种较难、需时较长(2-3年生时)并需与染色体倍性鉴定法相结合，因其形态变化较小而生长势又与平邑甜茶无融合生殖苗无明显差异；鉴别光叶型杂种因父本染色体组的影响加大而从形态上容易些，但也需过氧化物同工酶法或染色体倍性鉴定法相配合；皱叶型杂种因在苗期刚出1-2片真叶时就表现明显的标志性状、能从叶片形态上准确鉴别出来，毋须染色体倍性鉴定等复杂方法；因皱叶型杂种能早期鉴别，又表现明显的矮生性，因而选用"扎矮76"做父本不仅大大提高了平邑甜茶授粉后代中选择杂种的效率，而且提高了苹果无融合生殖型实生矮砧育种的效率。
