Effect of 2,3,5-Triiodobenzoic Acid on Flax
1970
Vetter, R. J. | Holden, D. J. | Albrechtsen, R. S.
Two varieties of flax (Linum usitatissimum L.), ‘Summit’ and ‘Nored,’ were treated with 2,3,5-triiodobenzoic acid (TIBA) in an attempt to increase lateral branching and seed yield. Rates of 100 ppm to 300 ppm TIBA successfully inhibited apical dominance and broke lateral bud dormancy; however, timing of treatment was critical for maximum bud breakage with minimum injury to the flax plant. The only significant effects on seed yield were decreases, but indications are that TIBA has the potential of increasing yield in flax when certain critical environmental factors are present.
