Abstract
The size of the seeds, shape index, shape of the seeds, 100-seed-weight, germination and emergence tests, the values of the test a rates, the speed of the imbibition and electrical conductivity were determined in 10 common bean cultivars in two group of red and white bean (Phaseolus vulgaris L.). In bean cultivars, the seed lengths (11.24-14.35 mm), the seed width (6.57-8.99 mm), the seed thickness (4.78-5.57 mm), shape index (1.66-2.09), 100-seed-weight (33.69-23.20 g), the power of germination (76-100%), the rate of emergence (86.66-100%), seed coat rate (7.76-10.53%), water imbibition (52.5-108.6%) and electrical conductivity (1.99-5.87 m Sc mg/seed) were found. In all bean cultivars, there was a positive correlation between the values of electrical conductivity (used as an indicator of seed secretion) and imbibition rate. Also, there was a negative relation between the values of electrical conductivity and power of germination (r = -0.78298**), between seed coat rate and water absorption at 3 h (-0.54**) between power of germination and water absorption at 3 h (-0.46**). There was a negative relation, but not significant between electrical conductivity and seed emergence. There was a very significant and negative relation between seed coat rate and power of germination between electrical conductivity and power of germination. Also there was a significant relation between power of germination and water absorption between seed weight and water absorption and there was a very significant positive correlation between seed coat rate and electrical conductivity in white bean. In red bean, there was a very significant negative correlation between electrical conductivity and seed weight positive significant correlation between water absorption at 19-23.5 h and power of germination. Also, correlation between water absorption at 1.5 h and electrical conductivity rate of emergence and electrical conductivity was positive and significant.
