Abstract/ Executive Summary:

A field experiment was conducted in the field of Seed Technology Division, BARI, Joydebpur during October 2013-April 2014 to evaluate appropriate post harvest fruit storage period for quality seed production. Zero and 1^st month of pumpkin fruit was stored for observed the seed quality. The seed of 1^st month stored fruit was given better quality in terms of germination percent, seedling dry weight and vigour index. Seed quality parameters were analysed upto one months of storage.

Location: In the field of Seed Technology Division, BARI, Joydebpur

Start Date: 00-10-2013

End Date: 00-04-2014

Program Area: Seed Technology

Commodity: Pumpkin

Objectives:

To evaluate appropriate post harvest fruit storage period for quality seed production.

Methodology:

A field experiment was laid out in the farm of seed Technology Division, BARI, Gazipur during rabi 2013-2014 under Randomized block design with four replications. The variety was BARI Misti kumra 2. The unit plot size was 4 x 3m with 2 plants in each plot. Well-matured pumpkin fruits were harvested and stored at ambient condition. The fruits were kept in ventilated wooden racks in a scattered manner. Every month, fruits were weighed individually and loss of weight was recorded in each month. The seeds extracted from respective treatments were cleaned manually and fresh weight was noted and expressed in gram. Dry weight of the seed was also recorded after proper dried in the sun. The moisture content of the seed was estimated by high constant temperature (drying at 130⁰C for 1 h) oven method(ISTA, 1999. ) After drying the seed to 8 percent moisture content, the weight of four replicates of 100 seeds each were recorded and expressed in gram. Germination test was conducted using sand medium. Number of normal seedlings alone was counted after eight day and expressed in percentage. Dry weight of the seedlings was estimated after drying them in an oven maintained at 70⁰C for 72 h.
