摘要
Abstract
This study aims to explore the effects of amino-oligosaccharin and various exogenous substances on sorghum seed germination,seedling morphology,and physiological characteristics under low-temperature conditions,this study used the sorghum variety'Red Tassel'is used as the research material.Soaking and hydroponic methods are employed to investigate the impact of amino-oligosaccharides(AS)combined with different concentrations of sodium nitroprusside(SNP),γ-aminobutyric acid(GABA),and salicylic acid(SA)on sorghum seed germination,seedling height,root length,basal stem diameter,fresh and dry shoot weight,fresh and dry root weight,enzyme activity,and chlorophyll fluorescence parameters.The findings are as follows:Soaking with 0.70 mmol/L AS+0.60 mmol/L GABA yields the best results for seed germination,while 0.70 mmol/LAS+0.25 mmol/L SA inhibits germination.Soaking with 0.70 mmol/L AS+0.03 mmol/L SNP and 0.70 mmol/L AS+0.50 mmol/L SA promoted seedling growth.Soaking with 0.70 mmol/L AS+0.03 mmol/L SNP and 0.70 mmol/L AS+0.60 mmol/L GABA enhances sorghum cold tolerance.In conclusion,0.70 mmol/LAS+0.03 mmol/LSNP is the optimum concentration for seed dipping.Hydroponic treatment with 3.0 mmol/L AS+1.0 mmol/L GABA shows the best results for promoting seedling growth.These findings provide a theoretical basis for the development of seed treatment agents to enhance seed germination,seedling growth,and cold tolerance in sorghum.关键词
