Nov 20, 2018· Breeding more heat-tolerant cultivars would stabilize seed yield and open new regions to field production. To support these efforts, we examined a variety of methods for screening large numbers of bean germplasm exposed to heat stress at the vegetative growth stage as opposed to the reproductive stage, which would prolong the screening process.
In the context of global climate change, heat stress is becoming an increasingly important constraint on grapevine growth and berry quality. There is a need to breed new grape cultivars with heat tolerance and to design effective physiological defenses against heat stress. The investigation of heat ...
This recently completed heat tolerant screening chamber in Zambia, is the first chamber to be built in Central Africa. As the mining operations are having to expand deeper and deeper, the high temperatures underground necessitate the screening of miners to ensure that their bodies are able to reject the heat at under these conditions.
Genetic and physiological studies of heat tolerance in hexaploid wheat (Triticum aestivum L.) By Hamid Shirdelmoghanloo Thesis submitted for the degree of Doctor of Philosophy School of Agriculture, Food and Wine Discipline of Plant Breeding and Genetics Australian Centre for Plant Functional Genomics (ACPFG) November 2014
Heat acclimation or acclimatization plays a large part in the body's physical responses and overall ability to cope with heat exposure. Heat acclimation is a broad term that can be loosely defined as a complex series of changes or adaptations that occur in response to heat stress in a controlled environment over the course of 7 to 14 days.

Mechanical screening, often just called screening, is the practice of taking granulated ore material and separating it into multiple grades by particle size. This practice occurs in a variety of industries such as mining and mineral processing, agriculture, pharmaceutical, food, plastics, and recycling.
Many evergreen trees can survive and even thrive in hot locations if heat-tolerant varieties are selected and the trees are correctly maintained. Some heat-tolerant evergreen trees are North ...
Environmental Control Engineering & Services [Pty] LTD was established in 1991 to provide engineering contracting services for air conditioning, ventilation and air pollution control within the industrial and mining sectors. Major areas of business are turnkey contracts providing specialised air .
Heat-tolerance-testing (HTT) protocol is used as a screening test for secondary prevention of exertional heat illness (EHI) in the military. Subjects whose test results are positive (heat-intolerant, HI) are presumed to be at higher risk of repeated EHI events than heat-tolerant subjects (HT) and are therefore prevented from return to combat ...

What is heat tolerance testing? Michael Bergeron, PhD on behalf of Sanford Health. Sports Medicine. Heat tolerance testing evaluates an athlete's current tolerance to exercising in the heat. Athletes should consider having this test performed if they have had a heat-related illness, especially exertional heat stroke, or a long period of no ...
M9962 is a potential genetic stock for use in a heat tolerance breeding programme. In addition, spikelet fertility at high temperature was representative of heat tolerance and can be used as a screening trait for heat tolerance during the reproductive phase on a large scale.

Most people don't like extreme heat, but you might find that it's impossible for you to be comfortable in hot weather if you have heat intolerance. Read on to learn about its potential causes ...
Heat stress tolerance is a polygenic trait, which is regulated by various genes, transcriptional factors, proteins and hormones. Therefore, to improve heat stress tolerance, a sound knowledge of various mechanisms involved in the response to heat stress is required. The classical breeding methods
The quality of cool-season turfgrasses frequently declines during periods of high temperature stress. Simple tests are needed to rapidly identify heat tolerant germplasm for incorporation into breeding programs. Facilitative screening tests have been devised, however, in the few studies that have been performed only immature and greenhouse or growth chamber-grown plants have been evaluated. To ...
Aug 10, 2018· Abstract. The methods include a protocol for screening heat tolerance of rice at the seedling stage; young seedlings were exposed to heat stress and the test takes 4–5 weeks and involves the visual scoring of symptoms which allows hundreds of seedlings to be evaluated in a short time.
physiological screening techniques to identify the tolerant germplasm are discussed in detail. Finally, the genetic, biotechnological, and breeding approaches to improve understanding of heat tolerance in cotton are also discussed. II. EFFECTS OF HIGH TEMPERATURE High‐temperature stress is among the least understood of the adversities
