Brassinolide is a plant growth regulator that mainly stimulates vegetative growth of plants, similar to gibberellic acid, and is mostly used for foliar fertilizers, which can quickly improve the quality of agricultural products and achieve a significant increase in crop yield.

The role of brassin

Brassinolide is applicable to food crops, cash crops, vegetables and fruits, etc., has strong rooting, promotes growth, raises seedlings, strengthens seedlings, protects seedlings, yellow leaf disease leaves turn green, promotes fruit expansion and early maturity, reduces disease mitigation, coordination Nutrient balance, drought and cold resistance, and enhanced crop resistance. It has obvious first-aid effects on dead seedlings, rotten roots, standing dry, and catastrophic phenomena caused by heavy crops, diseases, medicinal damage, and frost damage. It is effective after 12-24 hours of application and quickly restores vitality.

Avoid these spraying mistakes

1. Mashup error. Brassinolide is a growth-regulating substance required by plants, but when mixed with pesticides or fertilizers, care must be taken not to mix with alkaline drugs.

2. Use in rainy days. The weather is unpredictable. Pay attention to the weather conditions when spraying brassinolide on crops. Do not spray on rainy days. Because spraying the plant growth regulator on rainy days is equivalent to diluting the solution concentration again, so the expected effect cannot be achieved.

3. High temperature use. Can not be sprayed at noon, that is, when the temperature is the highest. At this time, the leaf surface evaporates quickly. One is that it is not easy for the crops to absorb it. The other is that the high temperature rapid evaporation makes the concentration of the brassin solution larger.

When can we use brassin

1. Early flowering. Spraying brassinolide one week before the flowering of fruit and fruit crops can promote multiple flowering, increase pollination and fruit setting rate, and lay the foundation for multiple results.

2. Young fruit period. Some plants will grow slowly after flowering. In this case, you can properly spray brassinolide to promote young fruit growth.

Precautions for brassin use

1. Do not spray when it rains. If it rains within 6 hours, spray again.

2. The best time for spraying is before 10 am or after 4 pm.

3, medication in strict accordance with the instructions. Wear protective clothing and masks and gloves when spraying. Do not eat anything in the meantime. Dispose of the equipment properly after medication.

Real-Time PCR Instrument

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.
