Abstract

The experiment on forced flowering of pineapple (Ananas comosus cv. Kew) in response to cold stress, ethephon, calcium carbide and activated charcoal was carried out at Fruit Research Farm, Department of Fruit Science, College of Horticulture & Forestry, Central Agricultural University, Pasighat, Arunachal Pradesh in the year 2013–14. The experiment was laid out in completely randomized block design with eight treatments and three replications. The treatments were: T1–Control, T2–Iced cold water, T3–NAA @ 0.002%, T4–1% CaC2, T5–1% CaC2+0.5% Activated charcoal, T6–0.025% Ethephon+0.04% CaC2+2% urea, T7–0.24% Ethephon+2% urea and T8–4% CaC2. Here, T7 (0.24% ethephon+2% urea) showed highest flowering percentage of 93.66 followed by T6 (0.025% Ethephon+0.04% calcium carbide+2% urea) with 91.33. Treatment T1 (Control) showed lowest flowering percentage of 24.66.
