| 1 | Comparative QTL analysis of maize seed artificial aging between an immortalized F_2 population and its corresponding RILs显示文摘Seed aging decreases the quality and vigor of crop seeds,thereby causing substantial agricultural and economic losses in crops.To identify genetic differences in seed aging between homozygotes and heterozygotes in maize,the seeds of a set of recombinant inbred lines(RILs) and an immortalized F_2(IF_2) population were subjected to artificial aging treatments for 0,2,3,and 4 days under 45℃ and 85%relative humidity and seed vigor was then evaluated in a field experiment.Seed vigor of all entries tested decreased sharply with longer aging treatment and seed vigor decreased more slowly in heterozygotes than in homozygotes.Forty-nine QTL were detected for four measured seed vigor traits in the RIL(28QTL) and IF_2(21 QTL) populations.Only one QTL,qGP5,was detected in both populations,indicating that the genes involved in anti-aging mechanisms differed between inbred lines and hybrids.Several QTL were identified to be responsible for multiple seed vigor traits simultaneously in the RIL and IF_2 populations under artificial aging conditions.These QTL may include major genes for seed vigor or seed aging.QTL qVI4 b and qGE3 a detected in the RIL population coincided with genes ZmLOX1 and ZmPLD1 in the same respective chromosomal regions.These QTL would be useful for screening for anti-aging genes in maize breeding. | Bin Wang Zhanhui Zhang Zhiyuan Fu Zonghua Liu Yanmin Hu Jihua Tang | 2016 | The Crop Journal2016，4，1： | 5 |
| 2 | Influential Intensity of Urban Agglomeration on Evolution of Ecoenvironmental Pressure:A Case Study of Changchun,China显示文摘In this paper,we study the interactive relationship between the agglomeration of urban elements and the evolution of eco-environmental pressure.We build an index system for evaluating the agglomeration of urban elements and eco-environmental pressure.Using the entropy method and response intensity model,we analyze how urban elements agglomeration influenced eco-environmental pressure in Changchun from 1990 to 2012,eliciting the changing features and influential factors.Ultimately,we conclude there is a significant interactive relationship between the agglomeration of urban elements and the evolution of eco-environmental pressure in Changchun.This is inferred from the degree of this agglomeration in Changchun having increased since 1990,with the degree of eco-environmental pressure first decreasing and then increasing.Alongside this,the impact of urban elements agglomeration on eco-environmental pressure has changed from negative to positive.The main reasons behind this shift are arguably the rapid growth of urban investment and ongoing urbanization. | LIU Yanjun ZHANG Jing LI Chenggu ZHOU Guolei FU Zhanhui LIU Degang | 2017 | Chinese Geographical Science2017，27，4： | 2 |
| 3 | Spatial Pattern of Female Non-agricultural Employment and Its Driving Forces in Guangdong Province,China:A Perspective of Individual and Family-level显示文摘Promoting women’s employment is not only the need of social and economic development,but also the historical mission of liberating women.This paper uses data from the 1%Population Sample Survey,taken in Guangdong Province in 2015,to explore how women’s marital status,education,and family environment affect the female non-agricultural employment rate(FNAER)on a county scale using a spatial-lag model.The results show that:1)The female non-agricultural employment rate in counties of Guangdong Province is low,with more than three-quarters of counties having female non-agricultural employment rate less than 50%.Moreover,the spatial distribution of FNAER is uneven,with the high-value areas concentrated in the southeast and the low-value areas mainly distributed in the central and western parts of Guangdong Province.2)From the perspective of industry,there are significant spatial differences among women.In the southeast,women are mainly engaged in the secondary industry,while in the central and western regions,women are mainly engaged in the tertiary industry.3)Women having better skills and more effective support from the elderly can improve the FNAER.Women having lower skills,smaller-scale families,a higher fertility rate,and households with two or more elderly members have a negative effect on the FNAER.4)Public policies suggest that improving women’s education and their family environment,building social welfare facilities,and repairing the family environment will increase the FNAER. | FU Zhanhui MEI Lin LIU Yanjun TIAN Junfeng ZHENG Rumin TIAN Jing | 2020 | Chinese Geographical Science2020，30，4： | 0 |
