Strawberries against gray mold
Strawberry grey mold, also known as rot disease, is a major disease in strawberry growing areas. Both greenhouse and open field cultivation are prone to occur. It directly harms flower organs and fruits and has a great impact on yield and quality.
Control measures: 1. Select resistant varieties, dressing with new high fat film before sowing, can repel underground pests, isolate virus infection, do not affect the germination and swelling function, strengthen respiratory intensity, and increase seed germination rate. 2. In early spring, timely removal of dead leaves and dry leaves, and spray a new high-fat membrane, anti-bacterial infection, early disease eradication of diseased inflorescences, remove the disease, reduce bacteria source; reasonable dense planting, balanced fertilization, and appropriate control of watering, prevent The plants are prosperous and the humidity in the garden is too large; cover the ground with plastic film or firewood to avoid direct contact of the fruit with moist soil.
PCR ( Polymerase Chain Reaction)
It provides a way to make more copies of a portion of DNA.
We need to have PCR ingredients that include DNA portion, Buffer solution, Primer+DNA (tap polymerase), and Nucleotides during the preparation step.
In the step of PCR sequence, there are three steps in this section.
Step 1 Denaturation
The addition of heat is needed to separate the two strands of the DNA molecule.
Step 2 Annealing
Temperature, is going to be cool in this step, should allow the primers to bind to the specific segments.
Step 3 DNA Synthesis
To make more copies of the DNA.
Those three steps above keep repeating to make enough copies of the DNA fragments. It is the principle of how PCR machine works.
Superyears General 2215 RT-qPCRadopts all-in-one with an industrial art design, combining the Analytical Instrument, Large touch screen, and Computer.
