Abstract

Background and Objective European plum Prunus domestica L. is a new introduction in the semi-arid environment of north-west India. The objective of the present study was to investigate the flowering phenology of European plum under the semi-arid environment of northwest India. Materials and Methods The studies were made on three varieties of the European plum Prunus domestica L. planted at the Horticultural Research Farm of CCS Haryana Agricultural University, Hisar India during 2009 and 2010. Results The results revealed that the flowering period of plum lasted for 40-42 days in both the observational years. The time of anthesis in all the three varieties was at 800 h in the morning. Maximum anthesis in the three varieties took place between 1200 and 1400 h and continued till 1800 h during both the years. Dehiscence of anthers started with the opening of flowers, flower longevity was about 3 days. Conclusion The flowering phenology of plum in the north-western part of India revealed that this is a winter flowering plant, anthesis and anther dehiscence peak is in the middle of the day and flower longevity is about 3 days.
