Abstract:
The size of the seeds, shape index, shape of the seeds, 100-seed-weight, the colour of testa, germination and emergence tests, the values of the testa rates, the speed of the imbibition, moisture content of the seeds and electrical conductivity were determined in 13 snap bean cultivars ( Phaseolus vulgaris L.). In snap bean cultivars, the seed lengths (12.0-17.24 mm), the seed width (7.07 –9.17 mm), the seed thickness (4.66-7.23 mm), shape index (1.52-1.98), 100-seed-weight (33.69-67.21 g), the speed of germination (24.0-98.0%), the power of germination (32.0-100.0%), emergence time (8.0-14.0 days), the rate of emergence (37.8-93.3%), seed coat rate (6.5-8.9%), water imbibition (89.3-122.5%), the seed moisture (4.1-9.8%) and electrical conductivity (4.3-14.5 mScmg/seed) were found. There was a significant and negative relation between testa rate and germination power (r = -0.7719), electrical conductivity and emergence rate (r = -0.8522), imbibition and seed moisture (r = -0.8617) in colored cultivars. A significant and positive relation was observed between water imbibition and electrical conductivity (r = 0.9207) and there was a significant negative relation between seed moisture and electrical conductivity. However, there was no significant relation in white cultivars.
