Effect of the Physical and Chemical Factor on Tobacco Seed Germination

XIAO Yang et al (College of Life Science,South-central University For Nationalities,Wuhan,Hubei 430074)  
[Objective] The physical and chemical factors affecting the germination ration of tobacco seed was researched.[Method] The method of shaker vibrate culture,MS medium culture,MS medium culture after GA3 treatment and soil culture were adopted.The tobacco seeds and dried seeds after soaked were treated and the effect of moisture,temperature and light and hormone on germination ration of tobacco seed was researched.[Results] The seed germination was improved under the condition of shaker vibrate culture.The treatment of MS medium culture was good for seedling growth.The seed dormancy could be broken while the seed was treated with the concentration of 0.1-0.9 mg/L GA3 and the stem growth was improved while 1-7 mg/L GA3 added in the treatment and the best effect was from the treatment of seed soaked with the 0.7 mg/L GA3 and 7 mg/L GA3 added in the medium. The dried seeds after soaked germinated earlier than non-treatment in the comparison experiment.[Conclusion] the dried seeds after soaked and treated with the suitable concentration of hormone could break the seed dormancy and promote seed germination.
