Target Root Starch Concentrations Before Storage: Testing the Model

Because carbohydrate reserves decline with long-term storage, it is important to know whether this depletion will affect subsequent survival and growth after planting. Sufficient target starch concentrations which enable the seedling to buffer itself against reserve depletion during storage, have not been defined. We found little evidence to support the model of a target (pre-storage) root starch concentration. No seedling target can be viewed alone. If the seedling is not preconditioned to grow but reserves are plentiful, a poor correlation between carbohydrate reserves and survival or growth is to be expected.
