Application of (2-chloroethyl) trimethylammonium chloride to strawberry plants decreased petiole lengths and suppressed the initiation and elongation of runners, but did not induce the formation of flower trusses in long photoperiods.
After an initial phase in which these responses were observed, the treated plants recovered and grew more strongly, producing longer petioles than control plants. It is suggested that this chemical might be useful for the control of runner formation in commercial strawberry growing.
