abstract
Mechanical injury can significantly cause losses in both the quality and quantity of the legume plants at the germination stage by affecting the stage directly or indirectly causing a pathogen attack. The objective of this research was to determine the mechanical injury effect on seedling development and visible disease on Vicia faba L. seeds at different seed ages. The germination and seedling experiments were conducted using one and two years old faba bean seeds with or without mechanical damage: [1) Non-injured 1-year-old seeds, 2) Mechanically injured 1-year-old seeds, 3) Non-injured 2-years old seeds, 4) Mechanically injured 2-years-old seeds] under climatic growth chamber. The trials were conducted a using completely randomized design with three replicates. End of the study, the results were obtained about seedling emergence ratio, seedling emergence time, seedling ratio, root and shoot length of the seedling, diseased seed, and seedling ratio. Faba bean seedling emergence time, seedling ratio, root length of the seedlings and diseased seed-seedling ratio were affected by mechanical injury and age. One-year old non-injured seeds showed a higher seedling rate than the other treatments. One-year-old injured seeds showed the shortest emergence time, and the highest diseased seed-seedling ratio. Two-year old seedlings from mechanically injured-seeds showed the least root length and disease ratio. This study made us think that the pathogen load may be higher in younger seeds.
