The Test of Chitosan Oligosaccharide Effect of Cold Resistance on Rice

During plant growth, biological Stress (virus, insect pest, fungus, etc.) and abiotic stress (cold damage, drought Harmful, salinity, mineral deficiency, heavy metals, etc.), where the temperature is one of the important conditions for plant growth and development.

As a subtropical thermophilic plant, rice is sensitive to low temperature environment. Low temperature will cause poor growth and development of rice seedlings or even death, severe seriously affect the rice yield.

According to the scientific studies shows that acetyl groups are involved in plant immune induction play an important role, and Chitosan Pro, as a structural unit of chitin containing acetyl groups, have antibacterial and disease resistance and other aspects of physiological activity, it is speculated that its. The field of rice cold resistance may have great application potential, but there is little research on it in the field of crop immune induction.

Material:

CHITOSAN PRO, COS content 90%, Molecule weight: ＜500DA.

Plant cultivation and treatment Select rice seeds with large, plump and uniform grains and soak them fully in clean water. Rinse the seeds of better quality that sink to the bottom with clean water and sterilize them by soaking in 75% ethanol solution for 15 min. Rinse several times with clean water until No ethanol residue. Will Rice seeds were soaked in deionized water at 30 °C for 48 h, and then Germinate at 30°C for 24 hours in the dark. After it is exposed, carefully choose the one that is exposed.

The rice seeds that have been grown are moved to a 96-whole plate for culture, and then moved to a plant light incubator for hydroponic cultivation. Culture conditions: temperature 25 ℃, relative humidity 75%, photoperiod 16 h/8 h (day/night).

The results would be coming out soon.
