Seed viability, germination and seedling growth of canola (Brassica napus L.) as influenced by chemical mutagens
Mutation induction is considered as an effective way to enrich plant genetic variation, particularly for traits with a very low level of genetic variation. The objectives of this study were to evaluate the effect of different dosages of chemical mutagens on seed germination, seed viability and seedling growth characteristics and to identify optimum treatment conditions for chemical mutagens bas...
متن کاملEFFECTS OF NaCl TREATMENTS ON SEED GERMINATION AND ANTIOXIDANT ACTIVITY OF CANOLA (BRASSICA NAPUS L.) CULTIVARS
Effects of salt stress on germination, seedling growth and activity of antioxidant enzymes in leaves of six cultivars of canola (Brassica napus L.) were investigated on two F1 hybrids (Hyola401, Hyola330) and four open pollinated cultivars (Zarfam, Okapi, RGs003 and Sarigol). Seeds were germinated under various levels of salinity (0, 50, 100, 150 and 200 mM NaCl solutions). An increase in NaCl ...
متن کاملGenome-wide association mapping unravels the genetic control of seed germination and vigor in Brassica napus
Rapid and uniform seed germination is a crucial prerequisite for crop establishment and high yield levels in crop production. A disclosure of genetic factors contributing to adequate seed vigor would help to further increase yield potential and stability. Here we carried out a genome-wide association study in order to define genomic regions influencing seed germination and early seedling growth...
متن کاملSeed germination and vigor.
Germination vigor is driven by the ability of the plant embryo, embedded within the seed, to resume its metabolic activity in a coordinated and sequential manner. Studies using "-omics" approaches support the finding that a main contributor of seed germination success is the quality of the messenger RNAs stored during embryo maturation on the mother plant. In addition, proteostasis and DNA inte...
متن کاملThe Influence of NaCl Priming on Seed Germination and Seedling Growth of Canola (Brassica napus L.) Under Salinity Conditions
A laboratorial study was carried out to investigate the effect of NaCl priming on seed germination and seedling growth of canola. Canola seeds were primed with 1% NaCl solution for 24 hours, at 20°C. Then primed and non-primed seeds were irrigated with seven different saline solutions consisted of 0 (control), 0.25, 0.50, 0.75, 1.00, 1.25 and 1.50% concentrations of NaCl. Results indicated that...
