Structure of the reproductive system and hectocotylus in males of lesser flying squid Todaropsis eblanae (Cephalopoda: Ommastrephidae)

This paper introduces new data on Todaropsis eblanae morphology, morphometry and functional aspects of the male reproductive system and hectocotylus. Spermatophores differ in specimens from the Atlantic Ocean (average length, 18.28 ± 1.45 mm, 15.63 ± 0.8% of mantle length; weight, 2.0–12.0 mg) and the Indian Ocean (average length, 24.8 ± 2.85 mm, 16.9 ± 2.1% of mantle length; weight, 35.0–39.6 mg) (t?=?3.14; p < 0.01 for absolute sizes and t?=?0.711; p > 001 for relative sizes). An additional important distinctive trait is the form of connection of the cement body with the ejaculatory tube. In recent years, T. eblanae has been regularly caught in the Barents Sea, meaning its range has extended to subarctic waters. The morphology and morphometry of the spermatophoric complex of organs did not vary in investigated parts of its range. Hectocotylus patterns and some important spermatophore traits distinguish Todaropsis from other Ommastrephidae.     

信息时代高校女性馆员如何提升自身形象

高校图书馆是一个女性馆员占绝对数量的部门,其形象的好坏直接决定了其所在图书馆的形象。在分析女性馆员正负面形象的基础上,探讨了提升女性馆员自身形象的对策。     

普通小麦T型与V型不育系花粉发育过程中苹果酸脱氢酶的变异

对不同发育时期花药的苹果酸脱氢酶(MDH)同工酶的研究表明:线粒体MDH(m-MDH)同工酶谱型是保守的,即只有量上的变化,质的差异不明显;不同类型不育系植株的胞浆MDH(s-MDH)同工酶表现不同:T型植株在花粉发育的整个时期s-MDH都存在,而V型植株在花粉发育的二胞期才出现s-MDH;此两不育类型植株从未出现微体MDH(g-MDH)。     

Breeding double low super hybrids with dominant genic male sterility three lines in Brassica napus

A double low homozygous two-type sterile line ZY-2AB, its near-isogenic temporary maintainer line ZY-4, and the full sterile line ZY-3 derived from the cross of ZY-2A with ZY-4, were developed to breed three-line dominant GMS hybrid in Brassica napus. Three years data showed that the ratios of sterile and fertile plants fit the expected 1 ： 1 ratio in ZY-2AB, and the 1：0 ratio in ZY-3, respectively. Some double low super hybrid combinations were screened out when the full sterile line ZY-3 was used as female parent, among which the combination 01Z24 increased 36.88 percent more yield than control and the conbination 98Z131 has been passed through the Sichuan Provincial Regional Test and registered in Sichuan Province. Two years data showed that the agronomic performance of the two-line hybrids derived from crosses of ZY-2A with restorer lines versus that of the three-line hybrids produced by ZY-3 was not different for any of the nine most important agronomic characteristics, revealing that near-isogenic line of homozygous two-type line was used as temporary maintainer could effectively avoid the disadvantage of threeway cross hybrid in breeding three-line dominant GMS hybrid.     

小麦雌性不育基因的微卫星标记定位

以普通小麦新601×雌性不育小麦XND126的F2群体作为育性调查以及基因标记群体.通过对育性基因的分析,确定在此组合中雌性不育基因由1对主效基因控制;结合混合分组分析法(Bulk Segregant Analysis,BSA),首次对小麦雌性不育基因进行了SSR分子标记,通过对一千对微卫星引物的筛选,确定微卫星引物cfd36标记与主效基因连锁,遗传距离为20.2cM.     

不可能的可能--试论冰心和丁玲笔下的女性形象

冰心和丁玲两位女作家在现代新女性面对不可能的选择时作出各自的选择。冰心高扬“爱的旗帜”,表现“家”的温馨,歌颂“圣母”之爱;前期的丁玲展示女性的欲望和活泼的生命力,致力于与男性世界争一片天空。两位女作家对女性意识的不同回答,成为关于女性解放的极有代表性的两翼。     

齿数大于100的质数直齿圆柱齿轮滚切加工方法

滚切齿数大于100的质数齿轮时,会因找不到合适的挂轮而影响加工。为解决这一问题,提出了“近似分齿”和“补偿”的加工方法,阐述了其加工原理、计算方法、误差分析。为其可行性提供了理论基础。经加工及检测得知,加工出的齿轮可达一般机械的精度要求。因此,实际加工中可采用近似分齿法和补偿法。
