低温对花生种子萌发与品质影响的研究进展

Research Progress on the Effect of Low Temperature on Peanut Seed Germi⁃nation and Quality

花生是我国重要的油料作物之一。二十世纪末,东北花生种植面积迅速增加,辽宁省如今已成为我国的第三大花生生产省份。但东北地区花生种植地形复杂,气候多变,尤其季节性低温和突发的极端天气和收获期低温等极易导致花生出苗率降低、出苗时间延长,甚至烂种、死苗,直接导致不同程度花生减产及营养品质变化。本研究综合详述了种植、收获、贮藏等各个时期花生遭遇低温处理后其生理生化功能、营养成分的变化及相应的防护措施,为探索不同时期低温对花生的影响提供理论依据,也为低温环境中花生的种植技术发展及花生产品低温贮藏保鲜提供参考。

Peanut is one of the important oil crops in China.At the end of the 20th century,peanut planting area in northeast China increased rapidly,and Liaoning province has now become the third largest peanut producing province in China.However,the terrain of peanut cultivation in northeast China is complicated and the climate is changeable,especially seasonal low temperature,sudden extreme weather and low temperature in harvest period.Low temperature easily leads to the reduction of peanut emergence rate,extension of emergence time,and even rot and death of peanut seedlings,directly leading to different degrees of peanut yield reduction and nutritional quality change.This study details the planting,harvesting,storage and other various periods of peanuts in its physiological and biochemical function after cryogenic treatment,the change of nutrient composition and the corresponding protective measures,to explore the different periods of low temperature on the different influence to provide theoretical basis,also for peanut planting condition and the low temperature fresh-keeping reference value.
