Abstract

A three-factor experiment was conducted at the Horticulture Laboratory, Hajee Mohammad Danesh Science and Technology University, Dinajpur during April- May 2014 to study the effects of the controlled deterioration (CD) on the yard long bean seed quality at the constant temperature of 350C to assess the physiological seed quality of both the two cvs. The 3 factors considered were: seeds of 2 varieties (Lalbeni/LB of Lal Teer Seed Ltd., and Kegarnatki/KN of United Seed Ltd.); 4 ageing periods (0, 4, 8 and 16 days); and 3 seed moisture contents (12, 16 and 20%). Thus, the 24 treatment combinations compared in the Completely Randomized Design (CRD) with the 3 repetitions for the 8 parameters were: % germination, % abnormal seedlings, % dead seeds, % soil emergence; and seedling evaluation test for the root and shoot lengths as well as their dry matter contents. Identical prototypes of notable (5-1% level) degradations were recorded everywhere. But the disparities were lucid under the extreme stresses. Moreover, highly noteworthy (1% level) relations were observed from all the traits ranging from -0.958 (normal seedling × abnormal seedling) to 0.953 (soil emergence × normal seedling). So, the controlled deterioration technique was very effectual in judging the physiological statuses of the seeds of the two varieties of yard long bean studied. Thus, the seed quality certification program, the suitable limits of vigor for the chosen traits could also be got by that technique. In addition, varietal differences were also found as Lalbeni of Lal Ter Seed Limited was better over Kegarnatki of United Seed Limited.
