Effect of Disinfection Time,Illumination and Temperature on Seed Germination of Antirrhinum majus

LIU Ziwei;JIANG Yarong;LEI Lei;ZHANG Yanni;College of Landscape Architecture,Northeast Forestry University;  
Antirrhinum majus was reproduced by seed and it was greatly meaningful for the productive practice to study the factors that affect seeds germination.Experiments of seed germination were conducted to study the best time of disinfection and the effects of temperature and light-different temperature gradient,heterotherm,light and dark on seed germination were also researched.The results showed that the germination rate of Antirrhinum majus when it was disinfected 6minutes by 2% NaClO reached the top level.The treatment of darkness made excessive growth of branches and leaves,seeding in the condition of light grew vigorously.Darkness and illumination had little effect on the germination rate.Antirrhinum majus' s seed germination rate was the highest(88.89%)when the temperature was25℃.The situation of 30℃/20℃could accelerate the procession of seed germination and improve the germination rate of seeds on the whole.
