water use efficiency is positively correlated with grain yield, and being used for indirect selection of high wheat yield in drought prone environments. yet little is known about genetic control of water use efficiency. in this research, a half diallel mating design was generated from crosses between 8 bread wheat to study the genetic of water use efficiency. parents and f1 progenies were plant...
tuberose aesthetically and commercially is an important flower that its importance is due to its potential for trade of cut flower, long vase life and essential oil industry. it is cultivated commercially by bulbs is needed to their storing properly after the harvest and quiescence to increase yield and flowering quality so that can be regulated flowering time according to market. experiments w...
Abstract Background Wheat spike architecture is a key determinant of multiple grain yield components and detailed examination morphometric traits beneficial to explain wheat the effects differing agronomy genetics. However, quantification has been very limited because it relies on time-consuming manual measurements. Results In this study, using X-ray Computed Tomography imaging, we proposed met...
In this study, factor analysis was conducted to determine the factors which contributed to the variation of quantitative traits and path analysis was performed to find the direct and indirect effects of yield components on grain yield in bread wheat. A doubled haploid population of 157 lines of wheat (Triticum aestivum L.) was evaluated for agronomic and morphological traits, using a randomiz...
The long spikes have been often recorded at the multiples of the electron cyclotron frequency in the ionograms of the topside sounders observed in low latitudes. There has not been sufficient explanation for the physical cause for occourrence of the long spike so far. Here, by interpreting this phenomenon as receiving the trapped cyclotron harmonic wave, some analyses for the length of spike ar...
Analysis of neural spikes is well established [4]. Many methods can be used to uncover distinct patterns of spikes. Consider two spike trains: 10101010 and 11110000, recorded in 1 s (where 1 represents the occurrence of a spike in a bin of length 1000/8 ms). The firing rates of both spike trains are identical (4 Hz), however the patterns are different; that is, the first train shows an oscillat...
Mint is an important medicinal herb that is cultivated in different parts of the world. In order to investigate the effects of salinity stress on morphological characteristics of spearmint (Mentha spicata L.), an experiment was conducted in 2013, based on complete randomized design, under hydroponic conditions, at Research Greenhouse of Faculty of Agriculture, Ferdowsi University of Mashhad, Ir...
This review discusses about phosphorus and zinc fertilizer consumption led to increasing yield components of the crops. The objectives this were focuses on impact application fertilizers crop plants their importance performance enhancement. other important aspect nutrition is interaction effect between them, especially in soils marginally deficient zinc. When fertilized together, such soils, yi...
Wheat yield can be enhanced by modifying the spike morphology and the plant height. In this study, a population of 191 F9 recombinant inbred lines (RILs) was developed from a cross between two winter cultivars Yumai 8679 and Jing 411. A dense genetic linkage map with 10,816 markers was constructed by incorporating single nucleotide polymorphism (SNP) and simple sequence repeat (SSR) marker info...
This research was carried out to evaluate the grain yield, yield traits and some quality characteristics of 18 bread wheat genotypes in seven different locations Thrace region using principal component analysis genotype + × environment interaction (GGE) biplot determine with high desired during 2016-2017 2017-2018 cropping years. The experiments were arranged a randomized complete block design ...
