Enhancement of Salinity Tolerance during Rice Seed Germination by Presoaking with Hemoglobin
Salinity stress is an important environmental constraint limiting the productivity of many crops worldwide. In this report, experiments were conducted to investigate the effects of seed presoaking by bovine hemoglobin, an inducer of heme oxygenase-1 (HO-1), on salinity tolerance in rice (Oryza sativa) plants. The results showed that different concentrations of the hemoglobin (0.01, 0.05, 0.2, 1...
متن کاملProteomics of rice seed germination
Seed is a condensed form of plant. Under suitable environmental conditions, it can resume the metabolic activity from physiological quiescent status, and mobilize the reserves, biosynthesize new proteins, regenerate organelles, and cell membrane, eventually protrude the radicle and enter into seedling establishment. So far, how these activities are regulated in a coordinated and sequential mann...
متن کاملSalinity Inhibits Rice Seed Germination by Reducing α-Amylase Activity via Decreased Bioactive Gibberellin Content
Seed germination plays important roles in the establishment of seedlings and their subsequent growth; however, seed germination is inhibited by salinity, and the inhibitory mechanism remains elusive. Our results indicate that NaCl treatment inhibits rice seed germination by decreasing the contents of bioactive gibberellins (GAs), such as GA1 and GA4, and that this inhibition can be rescued by e...
متن کاملEvaluation of salinity tolerance in rice genotypes
Salinity is considered as one of important physical factors influencing rice (Oryza sativa L.) production. Knowledge of salinity effects on rice seedling growth and yieldcomponents would improve management practices in fields andincrease our understanding of salt tolerance mechanisms in rice. This study was designed to assess the role of Saltol QTL in regards to effects of salinity on plant gro...
متن کاملSeed priming with bio-priming improves stand establishment, seed germination and salinity tolerance in canola cultivar (Hayola 401)
This research has been done to examine the effect of bio-priming on germination parameters related to seeds of canola cultivar (Hayola 401) under high salinity as factorial in seed laboratory of Shahed University based on a Completely Randomized Design (CRD) in three replications. Experimental factors included bio-primin...
