Yes, transpiration have effect over ascent of sap because trnspiration cause suction force which makes the sap rise upward. The process of rising of sapis callled ascent of sap.
I think so, i just put a piece of wood in my fire, and sap started rising up on the top & burned pretty well.. and I'm pretty sure pine sap is flammable. I'm going to say yes, sap is flammable.
The rising sap is 'milked' from the tree and used to make Maple syrup.
When the earth stops its rotation the sun will also stop rising.
Maple syrup can only be made in the spring, when the sap is rising in maple trees.
The only way to stop the rising prices of fetilizer is to stop growing crops for biofuels.
Generally the sap starts to flow between mid-February and mid-March. The exact time of year depends upon where you live and weather conditions. Sap flows when daytime temperatures rise above freezing (32 degrees Fahrenheit / 0 Celsius) and nighttime temperatures fall below freezing. The rising temperature creates pressure in the tree generating the sap flow. This is basically a transfer of the sap from the tree above the ground and the root system below the ground. The sap generally flows for 4 to 6 weeks, with the best sap produced early on in the sap-flowing season. These conditions are not met in the fall and the sap quits running in less than 6 weeks after it starts as stated above due to rising temperatures.
