Abstract
AbstractAir dried seeds of seven jute (Corchorus capsularis L.) cultivars were irradiated with different doses of X‐rays. JRC 1108 and JRC 412 were most and least sensitive to X‐rays, respectively. JRC 412 was susceptible to Colletotrichum corchorum both before and after X‐irradiation while JRC1108 became more resistant after treatment. Leaf diffusates but not leaf exudates of both non‐irradiated and X‐irradiated (40,000 r) cvs. exhibited antifungal activity which was more pronounced in case of irradiated JRC 1108. JRC 412 contained greater amounts of amino acids than JRC 1108 both before and after X‐irradiation. Signifinon‐irradiated, infected ones. The physiological implications of the results are discussed in relation to greater resistance of X‐irradiated JRC 1108.
