Abstract/ Executive Summary:

An experiment was conducted at the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh, to determine the post havest dormancy period of four modern bora rice varieties namely, BR2, Purbachi, Pajam and BAU 63, and to find out the effect of Mixtalol and KNOa in breaking such dormancy. Results revealed that all the four varieties had a certain period of dormancy which could not be broken by simple treatment with Mixtalol and KNOa. BR2 had a longer post harvest dormancy and Purbachi had a higher initial germina tion percentage as compared to others. Seeds treated with KN03 were able to produce seedlings higher in length and weight..

Keywords: Dormancy, Germination, Boro rice

Location: At the Agronomy Field Laboratory, Bangladesh Agricultural University, Mymensingh,

Start Date: 00-05-1987

End Date: 00-07-1987

Program Area: Postharvest and Agro-processing

Commodity: Rice

Objectives:

To determine the period of dormancy of four different modern boro rice varieties and to find out the effect of some chemicals in breaking such dormancy.

Methodology:

The experiment was conducted at Agronomy Field Laboratory, Bangla desh Agricultural University, Mymensingh, during May-July, 1987. Four varieties of modern boro rice namely BR2, Purbachi, Pajam and BAU 63 were used in the experiment. Freshly harvested and threshed seeds of these varieties were collected from farmers' field. Three methods were used tot breaking dormancy (a} without treat ment (soaking in water for 24 hours}, {b) treating seeds with 2% solutions of KN0 3 for 24 hours and (c) treating seeds with 3 ppm solution of Mixtalol{ParashR , Lever Brothers Bangladesh Ltd. ) ahw for 24 hours. The treated seeds were then blot drit1d and 400 seeds of each variety under each method wera put in patridishes for germination. This was replicated four times. The Experiment was repeated also four times taking seeds of o, 20,35 and 50 days after harvest (DAH).

Achievement/Findings:

Results revealed that all the four varieties had a certain period of dormancy which could not be broken by simple treatment with Mixtalol and KNOa. BR2 had a longer post harvest dormancy and Purbachi had a higher initial germination percentage as compared to others. Seeds treated with KN03 were able to produce seedlings higher in length and weight..
