Overview

Flowering phenology of thirty-two Carya illinoensis clones was observed and compared. The results showed that there exited some differences in flowering phonological phase from 2011 to 2014 and the duration of blossom process of all the thirty-two clones was from April 24 to May 21 in 2013. The lasting days of male flower of the thirty-two clones were 11-18 days and the whole flowering period of female flower were 9-17 days in 2013. The duration of receptivity stage of female flower and pollen shedding stage of male flower of thirty-two clones were all 3-8 days. According to the time order of blossom of male and female flowers, sixteen clones could be determined as protogynous type, ten clones were protandrous type and six clones the homogamic type. Eighty-six feasible pollination combinations could be selected according to the observation results. The best configuration scheme of clones was proposed. No significant difference was found in the length of male inflorescence among the thirty-two clones, but the
