Quantitative magnetic resonance imaging of Scots pine seeds and the assessment of germination potential
نویسندگان
چکیده
The availability of high germinability Scots pine seeds (Pinus sylvestris L.) is necessary for artificial forest regeneration. In this work, seed orchard were MR imaged to non-invasively investigate the association anatomical images and quantitative relaxation times with structure seeds. Relaxation time differences compared germination day also investigated. average whole T<sub>1</sub> (two methods), T<sub>2</sub> T<sub>2</sub>* 430±59 ms, 660±20 14±1.7 ms 0.83±0.33 respectively. It was observed that structures had statistically significant (p<0.05) in while no could be relation rate germination. Furthermore, obtained data radiographs. empty provided minimal MRI signal whereas intact mechanically damaged profound distinguishable structures. Mechanically hardest region, coat, not visible as opposed Some determined by radiography able germinate, mechanical faults distinguished MRI. As such, can seen complementary currently used methods optimize sorting interpretation potential.

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Magnetic resonance imaging of feline eye
The purpose of this study was to investigate magnetic resonance imaging (MRI) of the normal feline eyeand optic nerves using T1-weighted and T2-weighted images. A total of 6 healthy female domestic short haircats age 2-2.5 years and weighing 3.2 ± 0.4 kg were selected. Magnetic resonance imaging data werecollected using GEMSOW (Philips) at a magnetic field strength of 1.5 T. Dorsal, sagittal, a...
متن کاملSoftware Tools for the Analysis of Functional Magnetic Resonance Imaging
Functional magnetic resonance imaging (fMRI) has become the most popular method for imaging of brain functions. Currently, there is a large variety of software packages for the analysis of fMRI data, each providing many features for users. Since there is no single package that can provide all the necessary analyses for the fMRI data, it is helpful to know the features of each software package. ...
