Abstract/ Executive Summary:

Plant hormone has a good effect on rooting as well as seed production. It also helps in flower formation and pod setting of crop plants. Mortality is a common phenomenon for seed production through stem cuttings. Sometimes seed yield reduces to a great extent due to cutting mortality. In order to reduce mortality rate plant hormones IAA and IBA were used to increase the survibality of cuttings. Results showed that hormones had no significant effects on seed yield and cutting mortality of tossa jute var. O-9897, but IAA performed better both in respect of seed yield and cutting survibality.

Keywords: Plant hormones (IAA, IBA), Mortality, Cutting

Location: Jute Agriculture Experimental Station, Manikganj

Start Date: 01-03-2009

End Date: 31-12-2009

Program Area: Crop-Soil-Water Management

Commodity: Jute

Objectives:

To find out the effect of plant hormones on quality seed yield and to determine suitable plant hormone for reducing cutting mortality.

Methodology:

Plant hormones viz. Indole Acetic Acid (IAA) and Indole Butaric Acid (IBA) were used to find out the effect of hormones on seed yield and quality of O-9897 stem cutting. Cuttings from 120 days age of mother plants were collected and dipped into 50 ppm concentration of both the hormones for two hours with a control of without hormone. The soaked cuttings along with control were planted in unit plot of 3 m x 3 m in RCBD with three replications. Standard cultivation practices were followed in order to grow good crop. Cutting mortality was recorded time to time. After ripening the fruits plants were harvested and plot-wise seed yield were measured.

Achievement/Findings:

The preliminary study revealed that the seed yield was less and cutting mortality was high in case of hormones treatment than control but the differences were insignificant. Plant hormone IAA performed better than IBA in respect of seed yield and cutting survibality.
