Comparison and Display of the Water Contained in Early Somatic Embryos

摘要

This paper compares two methods that allow determining the total volume of water that occurs in early somatic embryos (ESEs). The first measurement was the measurement of proton density (PD) of early somatic embryos. This measurement was performed using MRI views (ISI ASCR Brno). The second technique was the weighing of dry sample of ESEs (Mendel University, Brno). These two methods were compared and the correlation coefficient of the two techniques was 0.816. Another important issue of the experiment was comparing the images of ESEs which were to show the biological processes in ESEs used relaxation times T_1 and T_2 to show the transition between the plant and the culture substrate.
