Abstract
The absence of boron in the root environment reduced the total linear growth of the radicles of the four dicotyledon and one monocotyledon species studied. After growth for 4 days in a boron-free medium, the growth rate of the maize radicle was comparable to that in a plus-boron medium, whilst the growth of the field bean radicle ceased. The minimum boron requirement for the unrestricted growth of the field bean (Vicia faba val'. minor) radicle over 120 hI' was 0·005 p.p.m. B. Each microgram of boron in this medium evoked a mean radicle elongation of 51 mm.
