Abstract:
Roselle (<em>Hibiscus sabdariffa </em>Var<em>. sabdariffa </em>L.) is an important medicinal plant used in indigenous pharmaceutical industries as a chief source in various synthetic drugs and antibiotics. The present study was carried out to examine the effect of seed deterioration on viability of Roselle seeds by subjecting seeds to accelerated ageing at 45± 2 <sup>0</sup>C temperature and 95 (%) relative humidity for 10 days. Various seed physiological parameters (moisture content, germination percentage, seedling vigor index I&amp;II) and biochemical parameter (electrical conductivity) were explored. The results indicated that seed aging had significant effects on seed quality parameters of Roselle with an outcome of decreased speed and percentage of germination and decreased percentage of normal seedlings along with increased electrical conductivity and moisture content progressively with the increment in ageing period (7, 8, 9 and 10 DAA). Prolongation of ageing led to deterioration of both seed germinability and viability indicating its poor storability
