Seed dormancy

of tallgrass prairie plant populations, as well as their response to disturbance (e.g., fire and grazing) and climatic variability, may be mediated principally through effects on the demography of belowground bud populations. Patterns of seed reproduction and seed bank populations have little influence on short-term aboveground population dynamics of tallgrass prairie perennials. Our results indicate that fire in tallgrass prairie strongly influences the production of belowground meristems and…

Quinoa is considered as future crop because of its unique growth requirement, allows quinoa to grow in various climate, soil, temperature and altitudes. Quinoa is a highly nutritious grain like crop grown primarily for its edible seeds, with outstanding protein quality and rich in vitamins and minerals. It does not only contain high amount of protein, but supplies complete protein which means by it has nine of the essential amino acids. Quinoa is a botanical fruit of an herb plant, considered as…

Sulfamethazine remediation potential of Arabidopsis thaliana root ABSTRACT The use of antibiotics in animals either as a growth promoting or as a disease treating agent has become a worldwide trend. Antibiotics being stable bioactive compounds are not fully absorbed into the animal system and are released into the environment through animal manure. This study aims to discern the effect of one such veterinary antibiotic, sulfamethazine, on Arabidopsis thaliana root and also the possible…

weather conditions and site environmental factors such as exposure, shade and wind (Wynn et al. 2000). Spores can be released suddenly through the drying of the annulus, and they may be dispersed by wind and water. Spores germinate without a period of dormancy. If sown within a week of collection they can show up to 95% germination within 5 days. Spores stored in a dry place may retain their viability for several years although they often take longer to germinate and prothallus development may…

The concentration of the auxin was not strong enough to maintain full dormancy of the lateral buds. The application of auxin is also dependent on the stage of development the plant is in for example auxin applied to a fruit tree can either drop the fruit or prevent the fruit from dropping depending on the stage the plant is…
