Fig. 11From: Adaptive minirhizotron for pepper roots observation and its installation based on root system architecture traitsProbabilities of root interception under different installation patterns. Notes The first number in the combined number represents horizontal angle of microrhizotron to referred plane, where 0 is 45° and 1 is 90°. The second number in the combined number represents radius of microrhizotron to the root center line, where 0 is 30 mm and 1 is 60 mm. The last number in the combined number represents vertical angle of microrhizotron to the root center line, where 0 is 30° and 1 is 45°Back to article page
