Abstract/ Executive Summary:

Monitoring on the panicle initiation, flowering, fruiting and seedling characteristics of Corypha taliera has been carried out. Biochemical composition of fresh and dry flowers together with the pericarp of the fruits have been analysed. Fresh flowers, fruits, seeds, and pericarp and testa weighed 13.75 mg/flower, 19.46 g/fruit, 6.47 g/seed, 12.89 g/pericarp and testa, respectively. The length of fruits and seeds were c 3.34 cm and c 2.33 cm, respectively while the breadth of the same were 3.14 cm and 1.94 cm, respectively. The protein content of fresh flower and pericarp were 12.78 and 14.70%. High energy content 345.97 Kcal was recorded in the pericarp and testa of the fruit. The first sown seeds were germinated in latterite clay soil between January and February and took approximately 30-48 days

Location: Dhaka University, Dhaka, Bangladesh

Start Date: 18-09-2008

End Date: 23-01-2010

Program Area: Knowledge Management

Commodity: Plum

Objectives:

To find the biochemical components of the flower and fruit of this globally endangered species.

Methodology:

Though grew in a scrub jungle, the species was cordoned within the boundary wall of the official residence of the Pro-Vice Chancellor of Dhaka University, Dhaka, Bangladesh because of safety reasons. Regarding fruiting, the plant was under continuous observation since 2000. After panicle initiation (visible on 18 September 2008) monitoring on its growth was done at definite intervals (1 week - 2 months) during which photographs of the plant canopy, stem, panicle, flower, fruits, etc. were taken and digitized . This activity continued from 18 September 2008 to 23 January 2010. For chemical analysis, the flower biomass was collected by spreading a synthetic oil-cloth (160 × 117 cm) underneath the tree for 5 days. During this period an amount 500 g of flower biomass was collected . It was then screened for separating debris manually and then poured in a polythene bag. The biomass was then transported to the BCSIR Laboratories, Dhaka for analysis. Ten selected fresh flowers were weighed individually with the help of an electronic balance (AND FR-200 MK II, Japan). Length and width of juvenile, young and mature fruits and their petiole and seeds were measured from a randomly selected 12 specimens with the help of a slide calliper and a screw gauge. The weight of fresh fruits and seeds were taken with the help of an electronic balance as mentioned above. The analysis on biochemical components was carried out on fresh flower as well as on dry flower biomass (dried at 100 ⁰C). The biomass was crushed in a mortar with the help of a pestle. The crushed material was then used to determine the amount of protein, ash, fat, moisture, fibre, carbohydrate, calcium, phosphorus, iron and energy content (NIN, 1976). Moisture content was determined with the help of a moisture meter (IB-30, Brand Chyo, Capacity 309, Readability = 0.0019). Mikrokjeldhal method was followed to determine the protein content. Ash was determined with the help of a Muffle Furnace (Model No. Carbolite RHF-1600). Pericarp and testa were separated manually from the fresh fruits and analyzed following the same methodology as described above.
