杂交和回交是常用的动、植物育种手段。杂交引起的父母基因互作导致遗传和表观遗传变异,比如经典的副突变(paramutation)可以跨代遗传。但是,由表观遗传引起的跨代遗传的机理缺乏全基因组水平上的研究。2月9日,南京农业大学多倍体杂种优势研究团队在Genome Biology(IF=13.583)上发表了题为Small RNAs mediate transgenerational inherita...
水分关键期干旱是影响玉米生长和产量的主要限制因子,构建此时期玉米干旱损失模型,研究干旱指数天气保险,对于合理设计天气指数保险和解决目前传统农业保险的困境,转移农业气象灾害风险具有重要意义。针对作物特定阶段单因子气象灾害影响难以剥离的问题,本研究在西北农林科技大学旱作农业长武试验站进行了连续3a的雨养玉米观测试验,利用田间试验数据(玉米生长发育数据、气象数据、土壤数据和田间管理数据)对CERES-M...
Phospho compost application is important with respect to soil fertility and plant nutrition. Therefore, the objective was to evaluate the influence of phospho compost application on P availability and...
A major challenge facing those involved in the testing of new plant varieties for Distinctness, Uniformity and Stability (DUS) is the need to compare them against all those of 'common knowledge'. A se...
The aims of this study was to examine the effect of the osmotic (NaCl) water stress on, growth and accumulation of endogenous compatible solutes of Bacillus amyloliquefaciens and Microbacterium oleovo...
Maize plays a unique role in the agricultural economic of world. It is a key stable crop which is used in a wide range of food industries and as a customary livestock feed in Iran. Also, it is one of ...
Quantitative trait locus (QTL) mapping can provide useful information for breeding programs, since it allows the estimation of genomic locations and genetic effects of chromosomal regions related to t...
With increasing human population against declining staple food crop yield trend, food insecurity is inevitable. Soil fertility problem has been identified as a major factor hindering maize productivit...
The computer-based CERES-maize model for simulating maize growth and development was used to simulate maize yield in a semi-arid region of Harran Plain of Southeastern Turkey in 2005 and 2006.
Using ecological data compiled from scientific literature on pest, pathogen and weed species characteristic in maize cultures in Hungary, we defined monthly climate profile indicators and applied the...
Response of maize grains (Giza 2) to the pre-soaking treatment with 10 mM trehalose was studied under salinity-induced stress conditions. Trehalose treatment induced growth of salt-stressed and unstr...
Salt damage has a broad physiological spectrum affecting metabolic processes. Application of 0.25 ppm brassinolide (BR) and 0.15 ppm salicylic acid (SA) as seed soaking and foliar spraying greatly al...
In this study, soil samples were collected from upland fields where maize and soybeans had been cultivated and the density of AM (arbuscular mycorrhizal) fungal spores and the percentage of soybean ro...
The concept of competition or complementarity between tree and crop roots for below ground resources have been a major debate in simultaneous systems. Root studies were conducted in three cropping sys...
Maize was grown in monoculture throughout the consecutive years 2003-2007 in Nowa Wieś Królewska (52o26’ N; 17o57’ E). A two factorial field experiment was established on a slightly acidic soil, ...
