Effect of number and timing of pinching on reproductive growth of potted poinsettia (Euphorbia pulcherrima Willd.)

An experiment to evaluate effects of pinching number (unpinched, once-and twice-pinched) and timing (early- and late-pinched) on reproductive growth of poinsettia was conducted. The results showed that late-pinched plants were delayed in floral induction, bract colour development and finish date c...
