Seed size in higher plants is an important agronomic trait, and is also crucial for evolutionary fitness. In flowering plants, the seed comprises three major anatomical components, the embryo, the endosperm and the seed coat, each with different genetic compositions. Therefore, seed size is coordinately determined by the growth of the embryo, endosperm and maternal tissue. Recent studies have r...
In Brassica napus breeding, traits related to commercial success are of highest importance for plant breeders. However, such traits can only be assessed in an advanced developmental stage. Molecular markers genetically linked to such traits have the potential to accelerate the breeding process of B. napus by marker-assisted selection. Therefore, the objectives of this study were to identify (i)...
conclusions reduction of surplus production factors through comprehensive planning based on the results of the data envelopment analysis can play a major role in cost reduction of hospitals and health sectors. in hospitals with a technical efficiency score of less than one, the original and projected values of inputs were different; resulting in a surplus. hence, these hospitals should reduce t...
construction plans are regarded as the basis of the economy in the society. any delays in the utilization of projects can cause to waste the investments and the loss of technical and economic justifications. in this paper, the barriers of on-time delivery in water projects will be scrutinized in mazandaran regional water company. so, the independent variables such as management obstacles, cultu...
Fusarium diseases of small grain cereals and maize cause significant yield losses worldwide. Fusarium infections result in reduced grain yield and contamination with mycotoxins, some of which have a notable impact on human and animal health. Regulations on maximum limits have been established in various countries to protect consumers from the harmful effects of these mycotoxins. Several factors...
Uncovering the genetic basis of agronomic traits in wheat landraces is important for ensuring global food security via the development of improved varieties. Here, 723 wheat landraces from 10 Chinese agro-ecological zones were evaluated for 23 agronomic traits in six environments. All accessions could be clustered into five subgroups based on phenotypic data via discriminant function analysis, ...
Backcrossed chromosome substitution lines (CS-B) have been developed with a homologous pair of chromosomes or chromosome arms of Gossypium barbadense (3-79) germplasm substituted for the homologous Gossypium hirsutum (TM-1) chromosomes or chromosome segments. We report on agronomic and fibre trait performance of four backcrossed chromosome or chromosome arm substitution lines including chromoso...
High nitrogen fertiliser applications are very common in many densely populated areas as in the North China Plain (NCP). A still growing population and an ongoing economic progress enforce that process. Remote sensing methods can help to optimize the N-management for diagnosing crop N status on a field and regional level. For that purpose, spectral and agronomic data were collected during the v...
In the information age, the speed of producing and supplying valuable information is considered as one of the keys to success in the organizations and institutes.The major objective of this study was to investigate and specify the effective factors in evaluating the BI systems with an emphasis on the integrity of organizational resources. First, five factors were determined as the major factors...
This paper examines decline in cocoa production at three historical moments: Trinidad in the early 18th century, Brazil in the first half of the 20th century, and Ghana in the recent transition from colonialism to independence. In each, decline followed promising expansion. Conventional explanations have been based on biological, agronomic, and market factors. Following a commodity systems appr...
