8000KG Proline shipping from Shanghai port
The role of Proline in agriculture is mainly reflected in enhancing plant stress resistance and regulating growth metabolism. Through osmotic regulation, antioxidant protection and promoting stress recovery, it improves the adaptability of crops to drought, salinity, low temperature and other adversities.
Main application directions and mechanisms of Proline
1. Enhance plant stress resistance
Osmotic regulation: Under stresses such as drought and high salt, Proline accumulation can maintain cell osmotic balance, prevent excessive water loss, and protect cell structure stability.
Antioxidant protection: Remove reactive oxygen species (ROS), reduce membrane lipid peroxidation damage, and reduce oxidative stress by increasing the activity of antioxidant enzymes such as superoxide dismutase (SOD).
Low temperature relief: Exogenous spraying of Proline can reduce the chilling injury index of peach fruit and maintain the fruit's ability to ripen and soften. The optimal concentration is 5mmol/L.
2. Promote growth and yield under stress conditions
Salt stress relief: Adding 0.3-5mmol/L Proline can reduce the inhibition of salt stress on crops such as celery and rice, and improve root morphology and biomass accumulation.
High temperature adaptability: Pretreatment of cucumber seedlings with 3mmol/L Proline can enhance nitrogen metabolism efficiency and osmotic regulation ability under high temperature and reduce membrane damage.
3. Seed germination regulation: Soaking seeds with 15mmol/L Proline significantly improves the germination rate and α-amylase activity of corn seeds under low temperature stress.
Through the above mechanisms and applications, Proline has become an important biological regulator in modern agriculture, especially in the context of frequent adversities caused by climate change, which has important practical value.
