The study looked at how the amount of sugar in the sap that reaches pea seeds can affect their growth potential. They found that seeds from plants with less nitrogen grew faster and received more sugar during a crucial growth period. This suggests that the sugar flow in the plant's sap plays a big role in how quickly seeds grow. Interestingly, the amount of nitrogen in the sap didn't seem to be as important for seed growth potential. This means that the sugar content in the sap might be a key factor in determining how well pea seeds develop.
