GRD1R LH temperature gradient culture plate

The Grant GRD1R LH temperature gradient culture plate design is used to conveniently obtain feedback results of various small components or materials such as seeds, small animals and plants, microorganisms, and various small components or materials at different temperatures. The design principle is to heat one side of the aluminum plate while cooling the other side, thereby forming a temperature gradient on the plate surface. By rotating the gradient plate again by 90 degrees, a porous temperature difference is formed. The $r $n gradient system can perform multi-directional temperature cycling, and the system can explore the temperature gradient direction within 24 hours. After that, the system automatically rotates the gradient direction 90 degrees on the layout and cycles back to the final direction

Application of temperature gradient incubator in exploring the effect of temperature on plant germination

Global climate change has led to significant changes in the germination cycle of plants. The Grant GRD1R LH temperature gradient incubator has been developed to investigate the impact of temperature on plant germination and contribute to ecosystem research.

The warming climate andAffected seeds

Global warming refers to the release of pollutants from human activities such as industrialization and the burning of fossil fuels了A large amount of greenhouse gasesThese gasesThe phenomenon of entering the atmosphere causing the Earth's temperature to gradually rise over the past few decades. Global warming has brought about a series of serious environmental problemsproblem：Rising temperatures lead to melting glaciers and polar ice sheets, causing sea levels to rise and posing a threat to coastal areasThe survival of islands；Weather events such as rainstorm, drought, hurricane, etcalsoFrequent occurrence, bringing benefits to human society and ecosystemssevereinfluence In addition, climate change also leads to ecosystem degradationsuffer, encounter, meet withDestruction and reduction of biodiversity.

In the context of global warming, plant diversityalsoHas been seriously threatened.

Taking seed germination as an example,Seeds within a certain temperature rangeonly thenSprouting,When the ambient temperatureAbove or belowcorrespondingthresholdtimeIt will not sprout.Germination is a "high-risk stage" in the plant life cycle that is directly regulated by temperature. With the increase of temperature, the dormancy period of many plant seeds is shortened, the germination time is advanced, and the plant growth cycle is not coordinated, which affects the stability of the ecosystem.

Faced with the constantly rising environmental temperature, seedsThe level of tolerance to temperature determines whether the species can surviveChanges have already occurredMaintain a stable population size in the environment.ButExploring the Effect of Temperature on PlantsseedThe impact of germination can help predict plant responses to environmental changes and determine species conservation strategiesin sequenceOrder, maintain biodiversity.
