Abstract/ Executive Summary:

Passion fruit has great potential to attract for its lucrative flavor, taste and deliciousness to grown up the economic condition of the framer in the developing country. Study of flower blooming can play vital role in developing high yielding varieties of this fruit. Filed and laboratory experiments were conducted at the Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh to determine the flowering behavior of yellow passion fruits (Passiflora edulis Sims.) at five flashes. The results revealed that third flash showed the best performance in respect of all floral biological attribute namely floral primodia initiation, period of flower bud formation to blooming, flowering duration, number of floral bud, number of flower bloomed, percent flowers opened, flowering interval, bud size, initiation, completion and withering of floral parts. Thus, the results may be concluded that third flash would the best for better fruit production.

End Date: 00-00-2009

Program Area: Variety and Species

Commodity: Fruit

Objectives:

The experiment was conducted to study the flowering pattern of passion fruit throughout the year under varied flashes.

Methodology:

The experiment was conducted at the experimental farm of the Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, Bangladesh where the climate is characterized by heavy rainfall. The soil of the experimental field was clay loam in texture and acidic in nature having pH 5.8. The experimental plot was well- drained high land where vine cuttings were transplanted in pits (50×50×50 cm³). The yellow passion fruit (Passiflora edulis Sims.) was used as test material for the experiment and vine cuttings were transplanted in the pits where the pit to pit distances were 2.5 m. Trellises required for the production of passion fruit for the life of the vine and a single row trellises system was used. The spacing of the passion fruit directly related to the spacing of the poles of the trellis and vines were pruned in late winter, irrigation and management practices were done as and when necessary. Yellow passion fruit vines begin flowering in the April-May, usually peaking in mid- August and continuing until October or November. Data on flower bud initiation, duration of flower bud initiation, days required from bud initiation to flower blooming were recorded. Other flowering attributes namely, duration at different flashes, flower buds per plant, percent of flowers bloomed, bud size, flowering initiation and completion, withering of floral parts were recorded. These parameters were computed from mean of two consecutive years (2008 and 2009) of 30 flowers. The collected data were analyzed statistically using MSTAT-C computer package (Michigan State University, East Lansing, MI, USA) following the methods of Gomez and Gomez (1984) and Kishore et al. (2010). The Analysis of Variance procedure (ANOVA), differences among treatment means were determined using the Least Significant Difference (LSD) at 5% level of significance.

Achievement/Findings:

The results indicated that duration of bud formation at different flashes was noticed variable and the longest duration was required under third flashing condition. Similarly, days required from bud initiation to flower blooming varied from 10 to 15 at different flashes. At third flash only 10 days were required to open flower form bud initiation. Plants produced maximum number of flowers per plant during third flash in June from the total buds. Flowering interval among different flashes were recorded variable. The shorted interval (3 days) was noticed between third and fourth flashes. Passion fruit produced largest size of buds at third and fourth flashes. Flowering initiation (blooming) during third flash was recorded at 09:05 h which was earlier than other flashes. Flowering percent at 12:00 was observed the highest (35%) during third flash followed by second and fourth flashes. Withering of sepals was noted to be delayed during third flash which positively contributed to ovary development and fruit setting.
