Abstract: In order to explore the most suitable soaking and germination conditions for the development of embryonic roots in hydroponic peanut sprouts, different gradients of temperature, soaking time and germination time combinations were set, peanut seeds were cultured, and the development of embryonic roots was recorded. The results showed that when the temperature was set at 25~27 ℃, the soaking time was 3~4 hours, and the germination was accelerated for 32~36 hours, the development of peanut bud and embryonic roots was better, and it was most suitable for peanut bud growth on the plug tray, resulting in the highest yield of harvested peanut buds.

Key words: soaking seeds and accelerating germination, hydroponic peanut sprouts, standardized production, development of embryonic roots, effect
