Abstract:
... Bean seed storage ability is of major interest for seed firms and depends, at least partially, on the effect of desiccation microclimate and desiccation rate on the mother plant; however, their effects are contradictory and not quantified. Therefore, our aims were (a) to predict seed desiccation rate from microclimatic variables at the pod level and (b) to measure the effects of seed desiccation r ...
