THE Savage Secret of Pumpkins
By, Russ Landry
June 26th, 2020.
The two Way River called the phloem in pumpkin plants transports the sugary carbon loaded products of photosynthesis and its nutrients from leaves to the sinks. Fruits and roots grow in size as a result of this transportation and storage. Cells of the phloem are pin cushioned together and joined to each other similar to layers of screens stuck together. Like neighbors these cells pass along the river of nutrients up or down the vine.
We’ve studied this before in Sink Source Relationship 101. The outcome was bigger roots grow bigger fruits. Later this became the calcium highway. Truth is for year’s pumpkin growers have long speculated on the exact nature of growing larger giant pumpkins.
