[Objective] This study aimed to investigate the effect of hydrogen peroxide on the seed germination of eggplant （Solanum melongena L.） Luba 2.[Method] The seeds of Luba 2 were separately soaked in 20％,40％,60％ and 80％ hydrogen peroxide solution for 2,5 and 10 min before seed germination.The germination rate and days to reach the maximum germination rate were calculated.[Result] Treatment with low concentrations （20％） of hydrogen peroxide for 2 and 5 min made eggplant Luba 2 germinate in advance,and shortened the time to reach the maximum germination rate.Treatment with high concentrations （60％ and 80％） of hydrogen peroxide solution for longer time （10 min） caused significant damage to the seeds,delayed seed germination,and reduced the germination rate.[Conclusion] This study will provide theoretical references for the production practices of eggplant.
[Objective] To study the long-term ultra-dry storage method and genetic stability of vegetable seeds.[Method] Seeds of Lycopersicum esculentum,Raphanus satuvus and Apium graveolen.were chosen as material.The changes of seed vigor,viability and genetic stability after ultra-storage were discussed by studying the seed potentiality,shoot length,germination percentage and the chromosome aberration rate of root tip cells.[Results] Maintaining the low moisture content,different vegetable species had different storage effects of the long-term storage seeds under normal temperature.The Lycopersicum esculentum and Raphanus satuvus seeds were more suitable to ultra-dry storage at normal temperature,and could keep good genetic stability,while the seeds of Apium graveolen had bad performance.[Conclusion] This study established the foundation of studying ultra-dry storage of vegetable seeds.
