Tiller is one of the most important agronomic traits which influences quantity and quality of effective panicles and finally influences yield in rice. It is important to understand ＂static＂ and ＂dynamic＂ information of the QTLs for tillers in rice. This work was the first time to simultaneously map unconditional and conditional QTLs for tiller numbers at various stages by using single segment substitution lines in rice. Fourteen QTLs for tiller number, distributing on the corresponding substitution segments of chromosomes 1, 2, 3, 4, 6, 7 and 8 were detected. Both the number and the effect of the QTLs for tiller number were various at different stages, from 6 to 9 in the number and from 1.49 to 3.49 in the effect, respectively. Tiller number QTLs expressed in a time order, mainly detected at three stages of 0-7 d, 14-21 d and 35-42 d after transplanting with 6 positive, 9 random and 6 negative expressing QTLs, respectively. Each of the QTLs expressed one time at least during the whole duration of rice. The tiller number at a specific stage was determined by sum of QTL effects estimated by the unconditional method, while the increasing or decreasing number in a given time interval was controlled by the total of QTL effects estimated by the conditional method. These results demonstrated that it is highly effective and accurate for mapping of the QTLs by using single segment substitution lines and the conditional analysis methodology.

S-a, S-b and S-c are three loci for F1 pollen sterility in cultivated rice （Oryza sativa L.）. Taichung 65 （T65） is all Sj/Sj at these three loci, while its F1 pollen sterile near-isogenic lines, TISL2 （S-b）, TISL4 （S-a） and TISL5 （S-c） is Sj/Sj according to their respective sterility locus. Using SSR molecular marker to detect the segregation of the allele Si and Sj in pollen calli population induced from different hybrid F1, which have different pollen sterility locus, showed that the segregation of allele Si and Sj was distorted. The distorted direction of pollen calli population in vitro was not the same as F2 population in vivo. The quantities of pollen callus carrying Sj were much more than that of carrying Siat S-a and S-c locus, the ratio of Si and Sj were 1：4.81 and 1：1.96 respectively. But the opposite tendency was observed at S-b locus, the ratio of Si and Sj being 1：0.35. At the same time, all these results were undisturbed by either culture medium or culture period.

Single segment substitution lines （SSSLs） each with a single chromosome segment from a donor under the same genetic background as the recipient were developed in rice by advanced backcrossing and molecular marker-assisted selection. Using the SSSLs, the QTLs for the important agronomic traits in rice would be detected under different environmental conditions. Detection of the QTLs controlling 22 important traits in rice was done with 32 SSSLs by the randomized block design in 2-4 cropping seasons. 59 QTLs were detected and distributed on chromosomes 1, 2, 3, 4, 6, 7, 8, 10, and 11, of which 18 QTLs were detected more than twice. Only 30.5% of the QTLs were detected repeatedly in different cropping seasons. Most of the QTLs of important agronomic traits were of little additive effects and instability. The QTLs controlling the traits, such as grain weight, grain length, ratio of grain length to width, and heading date were relatively stable. The stable QTLs usually had larger additive effects and were less affected by environment. The QTLs for the important agronomic traits were detected using the SSSLs in rice with high resolution under different environmental conditions. The instability of the QTLs may be the basis of the variation of rice plants during growth and development. It would be the genetic basis for improving yield and quality in rice cultivars by farming methods.

形而上学是传统哲学的核心,但是形而上学的命运却多灾多难。在当代,形而上学的合法性已经成为哲学家们经常讨论的话题,反形而上学的浪潮更是一浪高过一浪。在今天重新审视对传统形而上学进行过严厉批判又力图拯救形而上学的康德的思想,我们或许能够得到一些启迪。

关文运先生是我国著名的西方哲学翻译家,他曾经翻译过关于经验论、唯理论以及康德哲学的著作,为我国西方哲学的研究做出了重要贡献。但是,为时代所限,他的许多翻译著作又存在一些问题,甚至是误译。例如,他译的贝克莱《人类知识原理》就存在一些问题,有些地方甚至完全曲解了贝克莱的意思。根据笔者新译的贝克莱《人类知识原理》,对比关译本,列出有重要分歧的地方24处,并加以分析,这对于我们如何理解贝克莱哲学、对于西方哲学的中文翻译都是有意义的。

王阳明和贝克莱的"心外无物"的观点有诸多类似的地方,但也有些具体的差异。首先,关于"心"的问题上,王阳明的"心"或"心体"指内存天理的道德之心,而贝克莱之"心"是认识、产生观念或对象的精神实体。其次,在"物"的理解上,王阳明的"物"虽然... 详细信息

王阳明和贝克莱的"心外无物"的观点有诸多类似的地方,但也有些具体的差异。首先,关于"心"的问题上,王阳明的"心"或"心体"指内存天理的道德之心,而贝克莱之"心"是认识、产生观念或对象的精神实体。其次,在"物"的理解上,王阳明的"物"虽然可以泛指各种存在之物,但主要指意向性的活动和赋予对象的意义活动;贝克莱之"物"是指观念的集合物(对象、事物)。它们的共同点是"依心而在"。最后,在"心外无物"的观点上,王阳明的"心外无物"主要包括三种含义:意之所在便是物,事物之意义因人而存在,仁者的境界;而贝克莱所谓"心外无物"则有两层含义:作为观念的"事物"不能在精神之外存在,心外没有物质实体存在。

由华南农业大学选育的水稻单片段代换系S15对于野败型(WA)和矮败型(DA)细胞质雄性不育系均具有较强的恢复性。以野败型不育系博白A和矮败型不育系协青早A为母本,单片段代换系S15为父本杂交,采用分子标记辅助选择和连续回交的方法构建了2个BC3F2群体。利用与第1、第10染色体上恢复基因Rf3和Rf4两侧紧密连锁的SSR标记,从这2个BC3F2群体中筛选携带基因型Rf3Rf3/rf4rf4和rf3rf3/Rf4Rf4的单株,观察这些单株花粉和小穗育性,并利用202个多态性SSR标记分析这些单株的遗传背景,结果表明:(1)在同一细胞核背景下(S15),DA型细胞质的可恢复性好于WA型细胞质,单片段代换系S15中的恢复基因Rf4的恢复力大于恢复基因Rf3的恢复力。(2)单片段代换系S15中的恢复基因对于WA型不育系博白A和DA型不育系协青早A表现出质量-数量性状的遗传。在单片段代换系S15中,除了主效恢复基因Rf3和Rf4外,微效基因或者修饰基因也表现出对于博白A和协青早A的恢复性作用,而且效应较大。(3)在构建的2个BC3F2群体中,携带基因型Rf3Rf3/rf4rf4和rf3rf3/Rf4Rf4单株的遗传背景片段数平均为1.0,对应于恢复基因Rf3和Rf4座位的代换片段平均长度分别为12.9cM和18.4cM。
