Abstract/ Executive Summary:

Seed quality and health status of 11 vegetable crop seeds of viz. Cabbage (Brassica oleraceae var. capitata), Indian cabbage (Brassica oleraceae var. indica), Indian spinach (Basella alba), Spinach (Beta vulgaris var. bengalensis), Red amaranth (Amaranthus tricolor), Bitter gourd (Momordic acharantia), Bottle gourd (Lagenaria siceraria), Sweet gourd (Cucurbita moschata), Carrot (Daucuscarrota var. sativa), Radish (Raphanus sativus), and Turnip (Brassica rapa) collected from the greater Mymensingh region of Bangladesh were tested. The germination percentage of seeds of the collected samples ranged from 11 to 100. The highest germination was recorded in indian cabbage (100%) followed by carrot (92%) and radish (90%), while the lowest was recorded in indian spinach seeds (11%). Altogether 10 fungi were found associated with the seeds which were Alternaria spp., Aspergillus flavus, Aspergillus niger, Botrytis cinerea, Chaetomium funicola, Curvularia spp., Fusarium spp., Penicillium spp., Phoma spp. and Rhizopus spp.. The highest total seed-borne fungal infection was found in bottle gourd (155%) followed by sweet gourd (145%). The lowest infection was found in turnip seeds (6%). The maximum number of dead seeds was found in indian spinach (89%) and no dead seed was found in indian cabbage. Among the vegetables seed samples, seedling vigour ranged from 59 to 3083, where the highest seedling vigour was observed in sweet gourd (3083) and the lowest was in indian spinach (59).

Objectives:

The present research was undertaken to assess the health and quality of vegetable seeds collected from the Mymensingh region.

Methodology:

Seeds of different vegetables under Mymensingh region were collected from Bismillah beez vander, Krishan Agro service, New Mousumi beez vander, Sharika seed store, AlMadinabeez vander, Al-Amin beez vander, Yasin beez vander, Mousumi beez bitan, Arian seed company, Krishi beez vander, Angkur beez bitan and Islamia beez vander. All experiments were conducted at Seed Pathology Centre, Bangladesh Agricultural University, Mymensingh during the period from 2010 to 2011. Seeds of three different categories of vegetables were studied for their health and quality. The categories of vegetables were i) Leafy vegetables viz. Cabbage, Indian cabbage, Indian spinach, Spinach and Red amaranth, ii) Cucurbits viz. Bitter gourd, Bottle gourd and Sweet gourd and iii) Root vegetables viz. Carrot, Radish and Turnip. A working sample of 400 seeds was used for Blotter test for detection of seed-borne fungi following the International Rules for Seed Testing (ISTA, 2001). Growing on test was conducted with 200 seeds for germination, normal seedlings, abnormal seedlings, diseased seedlings and dead seeds that were recorded thrice at 7, 14, 21 days after sowing. For determination of seedlings vigour of vegetables, 10 seedlings per replication were selected randomly and their individual shoot and root length were measured. The vigour of the seedlings was determined by the following formula of Baki and Anderson (1972). The experiments were conducted in Randomized Complete Block Design (RCRD) with four replications and data were analyzed by using statistical package program MSTAT-C. The level of significance and analysis of variance along with the Least Significant Difference (LSD) were done following Gomez and Gomez (1984).

Achievement/Findings:

From the findings of the present study, it may be concluded that the seed samples of different vegetables collected from Mymensingh region are not so good quality except indian cabbage, radish and carrot. Therefore, routine seed health and quality study should be undertaken in order to reveal the exact picture regarding the prevalence of seed-borne fungi and the role they do play on seed health.
