FLORAL BIOLOGY OF BER (ZIZIPHUS MAURITIANA LAMK.) CULTIVARS UNDER SEMI-ARID CONDITIONS OF HARYANAHARDEEP, MUKESH KUMAR, MANISH KUMAR, RAJESH MOR, GOVIND1 AND DEEPAK SANGWANAbstract A field experiment was carried out at experimental orchard, CCS Haryana Agricultural University, RRS, Bawal (Rewari), Haryana to study the floral biology of ber. Nine cultivars of ber planted during 2007 (13 years old plants) at 7 m à 7 m in randomized block design were selected for evaluation. The plants were tagged in the month of April. These cultivars were observed to study the variability in floral biological parameters. The floral parameter such as flowering habit in the selected cultivars was recorded on the leaf axis of secondary branches. The ovary was observed superior to half-inferior among the cultivars. Anthesis occurred in forenoon in some cultivars whereas, in afternoon in others. Dehiscence time was observed from 1 to 3 hours in different cultivars. Date of initiation of flowering to end of flowering, flowering duration, time taken from flowering to fruit setting, time taken from fruit setting to fruit maturity varied as 16 August to 31 October, 49-62 days, 16-21 days and 128-151 days, respectively. |
