G'day gang,
I was thinking that all the nutrients that go into the pumpkin have to flow
along the thin pipe that feeds the fruit. At the moment my fruit are putting
on about 15 kg a day through a vine of about 2-3 cm in diameter, that is a
cross-sectional area of about 7 sq cm. Assuming the liquid weighs about 1kg
per litre then we have a flow rate of 15 liters per 24 hrs through 7 sq cms.
That means about 100 ml per hour per sq cm of cross-section (and faster at
night). This should be measurable along the lines that blood flow is
measured. We have a conductor (the liquid) and by creating a magnetic field
you would generate an electric field, the strength of which would indicate
the flow rate.
By clamping sensors based on this principle around various vines you could
determine where the nutrients were going. It should be easier in a well
trimmed Christmas Tree vine.
Does anyone know if such sensors are used in plant science?
