Bud break percentage of 'Suli' pear after 21 days of forcing conditions. Dormant shoots of field-grown ‘Suli’ pear trees were collected on Nov. 15, Dec. 15, Jan. 15, and Feb. 15, 2010–2011, and kept in water in a phytotron at day/night 25 ± 1/18 ± 1°C, with a 12-h photoperiod of white light (320 μ photon mol m^-2 s^-1) and 75% humidity. Percent bud break in 12 shoots per sampling period was assessed after 21 d.
