Relative growth rate is the measure of the ability of the plant to produce new plant material.
Growth = 19 – 5 = 14 cm
Period = 7 days
Growth rate = 14/7 = 2 cm/day
Relative growth rate = 2/5 × 100 = 40%
Growth = 19 – 5 = 14 cm
Period = 7 days
Growth rate = 14/7 = 2 cm/day
Relative growth rate = 2/5 × 100 = 40%
