“…A similar peak in fructose and glucose was reported in the same germination phase of Medicago sativa, along with that of amino acids, such as proline, known to be part of the osmoregulators. 49,50 For fresh seeds, this third time period was characterized by a drastic decrease in the longest relaxation times, T 1z and T 2d , as well as their proportions P 1z and P 2d , with a concomitant increase in the proportions of P 1y , P 2c , and P 2b of the intermediate relaxation time components T 1y , T 2c , and T 2b ( Figure 3A,B). These changes occurred while modifications of the cell wall polysaccharide chemistry related to cellulose-rich primary wall synthesis were observed along with an increase in embryonic axis size in the seed.…”
