Abstract
Heterotrophic seedling growth has described as the product of the following dynamic and to transmit seed reserves and the conversion efficiency of mobilized seed reserves to seedling tissue. This research was carried out to evaluate germination and seedling growth of wheat seed (N8019) in the form of combined analysis design with CRD arrangement. Treatments consisted of 4 levels of waterlogging period (0, 24, 48 and 96 hour) and in 3 levels of tempreture (5, 10 and 20 ˚C) in tetraplicates. Results indicated that percentage and rate of seed germination decreased with increasing waterlogging period under all tested tempretures, however, seedling growth rate decreased significantly only with increasing waterlogging period. Study of two components related to the heterotrophic growth of wheat seedling revealed that seed reserves utilization decreased significantly, while conversion efficiency of mobilized seed reserves did not affect significantly.
Keywords: Percentage; Rate of seed germination; waterlogging and Conversion efficiency
