Dear Ecolog-Listers:
Basic botany question. All along I have understood that the so-called "sap"
from which maple syrup is manufactured comes products transported in the
xylem. Thus, the liquid is harvested as it travels upwards from the roots
into the shoot as the plants begins to increase its me
Here's an exercise from a Plant Physiology class that gives a more thorough
explanation of sucrose-laden sap flow through the xylem, which is only a spring
phenomenon:

As for the NPR story, I am not sure that people have alw
Unfortunately, that one quip in the NPR piece had it wrong; lets hope it was

The sap flows up through the xylem in the spring. Cold temperatures in the
winter causes sap in the tree to freeze, forming air bubbles and
Interesting story...I think the surprising part was supposed to be that small
trees can produce large amounts of sap. My brother runs a small sugaring
operation in Connecticut and our family collected sap when I was a child. We
always knew which direction (up) the sap flowed in, and so do the
