Progress of Research on Seed Priming in Major Field Crops | Chapter 1 | Agricultural Sciences: Techniques and Innovations Vol. 7

 

Seed priming is a pre-sowing technique where seeds are hydrated with solutions of specific osmotic potential for a set period, often with organic or inorganic chemicals at controlled temperatures. This process repairs cell structures, activates enzymes, converts stored materials to energy, and initiates metabolism before germination. Seed priming promotes rapid, uniform germination, dormancy breaking, water and nutrient use efficiency, improved tolerance to environmental stresses, and resistance to diseases. It is an affordable, effective technology that enhances seed performance and early plant development in field crops. Seed priming methods include hydro-priming, halo-priming, hormonal, osmo-, solid-matrix, nutrient, nanoparticle, and bio-priming. Advanced seed priming methodologies such as nanoparticles, gamma-ray, magnetic-ray, and ultraviolet irradiation have prompted concerns regarding their potential adverse effects on plants, human health, and the environment.   The optimal treatment differs between species, cultivar, and seed lots. Such variability is a major limitation of the priming method, and hence, numerous trials are required to identify the most appropriate strategy for each situation. Selection of the right priming technique is crucial for realising optimal results with this cost-effective approach and is a valuable technology for sustainable agriculture.  The review aims at summarising the seed priming principles, mechanisms, and recent research advances made adopting different methods of seed priming and the beneficial effects of seed priming on morpho-physiological and biochemical characters in major field crops such as rice, wheat, maize, sorghum, greegram, blackgram, pigeon pea, chickpea, groundnut, soybean, sunflower and sesame.

Impact of Emerging Pandemics on Cardiovascular Health and Psychological Stress: A Systematic Review | Chapter 2 | An Overview of Disease and Health Research Vol. 3

Introduction: Every epidemic that breaks out could cause confusion and fear in society. Little is known regarding behavioural changes and health condition responses, despite the dramatic warning in the media. There is an extremely strong correlation between the onset of cardiovascular disease and the pandemic.

 

Aim: The goal of the study was to find out how the pandemic's stress affected the heart's regular physiological processes.

 

Methodology: Information about the potential effects of psychological stress brought on by the pandemic on cardiac physiological function was gathered from several databases. Using the various databases, studies that examined the relationship between stress on CVDs or the emergence of the pandemic and the cardiovascular system were found. A total of 37 studies were chosen for full assessment out of the more than 200 abstracts that were screened to ascertain whether all inclusion requirements were satisfied. Among these studies, one focused on evaluating the stress levels of front-line medical staff in China, particularly those working at a provincial hospital during the coronavirus outbreak and severe acute respiratory syndrome (SARS).

 

Discussion: As a result, a study revealed that medical staff members experienced significantly higher levels of moderate and severe anxiety than their administrative counterparts. Prior research on severe acute respiratory syndrome emphasised the importance of increasing awareness of mitigating strategies. Because a larger perceived danger of infection was more likely to result in an increase in cautionary events in contrast to contamination, this strategy was taken into consideration with the underlying insights of risk and anxiety. The implementation of control measures raises the stress level, which may cause CVD to develop.

 

Conclusion: There is adequate evidence that illustrates the physiological manifestation of the respiratory system and obstruction of the blood flow that might lead to the development of CVD. If not properly controlled might lead to death due to a heart attack.
