Patterns of Reserve Mobilization in Seeds —Examples

Patterns of reserve mobilization 1. Pattern of mobilization not associated with vascular strands (commonest type) 2. Mobilization begins around vascular strands 3. Mobilization around vascular strands delayed 

Metabolic changes associated with germination and growth (in darkness) 

Mature dry seeds of Lupinus luteus contain no starch, but starch grains appear during mobilization of the protein and lipid reserves [102]. The source of material for starch synthesis is not photosynthesis (for starch grains also form in dark-germinated seeds), nor the proteins, nor the small quantities of 

Finally a word about the endospermic legumes. As we have mentioned previously, the galactomannan reserves of the endosperm of these seeds might be more important for retention of water within the seed to allow early embryo growth than for the provision of nutrients. The cotyledons of these legumes are usually rich in fats and protein but their mobilization does not appear to have received any attention.
