Question 10

During an ecophysiological study of transpirational water loss in Rosmarinus officinalis (rosemary), a researcher used a potometer to monitor a cutting under controlled wind-tunnel conditions. The rate of water uptake by the cutting was measured to be 17 mm3 min−117 \text{ mm}^3 \text{ min}^{-1}17 mm3 min−1. The total leaf surface area of the cutting was estimated using a leaf area meter to be 30 cm230 \text{ cm}^230 cm2.

Calculate the rate of transpiration for this cutting in cm3 hr−1 cm−2\text{cm}^3 \text{ hr}^{-1} \text{ cm}^{-2}cm3 hr−1 cm−2.

Give your answer in standard form to 2 significant figures.
