Abstract:

To identify the flowering biological characteristics of ‘Tianyou 6’ which was widely planted in the south of Loess Plateau, the flowering process for group and individual, pollen viability and stigma receptivity of ‘Tianyou 6’ were investigated from 2009 to 2011. The results suggested that ,the full-bloom stage for group flower started from day 9th and ended at day 31th science the first flower appeared, the blossom number of ‘Tianyou 6’ in the day 9th was significant higher than that of first 8 days. The blossom number for per plant increased with time passage during the early flowering stage and full-bloom stage, and it reached the maximum in the day 19th (25.43 flowers per plant per day), then decreased with the time. The blossom time for ‘Tianyou 6’ was mainly focused on 6:30 am to 12:30 am, especially from 8:30 am to 10:30 am. The flowers had the strongest pollen viability during the first 1 hour since it blossomed, and the stigma had the strongest receptivity in the first 1 hour too, with the passage of time, the pollen viability and the stigma receptivity become more and more weakly. For each day, the pollen had the strongest viability from 9:00 am to 15:00 pm.
