Abstract:

A laboratory experiment was conducted at Agronomy Laboratory of Agrotechnology Discipline, Khulna University, Khulna, Bangladesh during 10 September to 1 October 2008 to determine relationship between chloride salts of sodium and potassium with germination and seedling growth of BRRI dhan 41. Potassium chloride and sodium chloride were used as two salt sources and each sources had five different levels of salt viz. 0, 75, 150, 225, and 300 mM. Data were collected on germination percentage, energy, capacity & speed and the length of root and shoot length as well as dry weight of root and shoot per plant. There were wide variations in all parameters of germination, shoot length, root length and dry weight of root and shoot due to the treatment with the two different salt sources. Germination percentage, energy, capacity & speed and the seedling growth (shoot length) of the variety gradually decreased with increasing concentration of salt solutions. Germination and the length of root & shoot were negatively related to salt levels.
