Hundred and fifty seed samples of white jute (Corchorus capsularis L.) belonging to four seed classes were collected from different sources of Bangladesh. The seed classes were breeder, foundation, certified and farmers’ seeds. Breeder seeds had the best performance in all the seed quality attributes as compared to foundation, certified and farmers’ seeds. The lowest performance was observed in...

Dormancy is one aspect of tuber physiological age that begins with potato tuber initiation. During dormancy, biochemical and physiological processes do occur but they do not trigger immediate morphological changes, yet these processes are relevant for the number of sprouts produced after breaking of the dormancy and for the growth vigour of the seed tuber. This review article reports that dorma...

Seed deterioration is an unavoidable process to which seeds of oilseed plant species such as sunflower are especially sensitive. This study aimed determine whether different invigoration techniques can improve the attributes germination in and alleviate effects seed ageing. Both aged non-aged were subjected by pre-soaking with distilled water 3% KH 2 PO 4 for 24 hours at 25°C. Germination perfo...

The question of whether or not perennial plants senesce at the organism level remains unresolved. The aim of this study was to unravel whether or not plant age can influence the production and composition of seeds. Flower and seed production was examined in 3-, 8-, and 13-year-old Cistus albidus plants growing in experimental plots corresponding to the F2, F1, and F0 generations of the same pop...

Transporter genes and cytokinins are key targets for crop improvement. These genes are active during the development of the seed and its establishment as a strong sink. However, during germination, the seed transitions to being a source for the developing root and shoot. To determine if the sucrose transporter (SUT), amino acid permease (AAP), Sugar Will Eventually be Exported Transporter (SWEE...

Seed dormancy is a genetically inherited trait whose intensity is modified by the environment during seed development and maturation. In order to study the effect of harvest time on the seed quality and optimum time of sowing to obtain good quality seeds, freshly threshed seeds of ten diverse rice genotypes harvested from six environments were evaluated for seed dormancy and seedling vigour ind...

Seed vitality and vigour are the two most common parameters related to seed quality. It is crucial have reliable methods tests for quality testing. The standard germination test can be used predict field emergence, but laboratory testing conditions often in conflict with conditions. Validated evaluation legumes conductivity test, accelerated ageing tetrazolium test. Also, other types of been so...

Temperature and relative humidity in combination cause rapid decline in seed quality during storage. To maintain the seed quality in storage a number of physical and chemical treatments are used. Magnetic field treatment is one such physical treatment practiced to improve the seed quality. An experiment was conducted to investigate the efficacy of this treatment to improve the storability of se...
