environmental-testing
Environmental testing measures the performance and resilience of plants and plant materials under controlled stresses such as temperature extremes, humidity variations, salinity, and pressure changes. In plant science, this technique is essential for developing climate-resilient crop varieties and understanding how plants respond to environmental stress. By systematically evaluating plant performance under diverse conditions, researchers can predict field survival and accelerate breeding programs for crops adapted to changing environmental conditions.

Researchers tested four methods for counting microbes in seawater and found that manual cell counting and quantitative PCR (a DNA-based technique) were the most reliable and consistent for studying how plastics break down in the ocean.
Manual cell counting and quantitative PCR were both repeatable and reproducible in seawater environments.
All four methods were evaluated for compatibility with seawater, but only two passed as reliable for biodegradation testing.
The study recommends that marine plastic biodegradation tests should always pair results with a carefully vetted microbial quantification method.
