Transpiration rates for whole plants, individual branches or tillers is determined by techniques that live the speed at which sap ascends stems. All of those ways use heat as a tracer for sap movement, however they’re basically completely different in their operative principles. 2 ways usually utilized, the stem heat balance and trunk sector heat balance ways, use the warmth balance principle; the stem is heated electrically and therefore the heat balance is solved  for the number of warmth haunted by the moving sap stream, that is then accustomed calculate the mass flow of sap within the stem. within the heat-pulse technique, instead of victimisation continuous heating, short pulses of warmth are applied and therefore the mass flow of sap is deter-mined from the rate of the warmth pulses moving on the stem.
