The Effects of Testa Colour Temperature and Seed Moisture Content on the Occurrence of Imbibition Damage in Beans

Authors: İbrahim DEMİR

Abstract: The effects of differences in testa colour (white, red), imbibition temperature (4_0C, 20_0C) and seed moisture (10 % >, 13 %<)on the occurance of imbibition demage in beans (Phaseolus vulgaris L., cv. Yalova 5,4F-89) were invastigated. The seed quality criteria were germination, emergence and seedling growth. The coloured seed coat cltivar was superior to the white one with regard to all quality measurements. The higher the imbibition temperature, the less imbibition damage occured. Seeds that had a moisture content higher than 13 % were less sensitive to imbibition damage. However, reduction in seed moisture and imbibition temperature caused more damaging effects on the white cultivar than the red one. This experiment clearly shows that bean seeds must be sown at an optimum soil temperature, wetness and seed moisture content. Particularly, more attention needs to be paid to white cultivars.
