Abstract: This paper discussed the effect of budburst detached peach branch with different chemicals, different temperature and different grads by hydroponics. The result shows that all different chemicals can bring forward the time of the first bud burst in different degree, and GA3 or CTK can make the budburst rate exceed 50%, this explain these is very availability to break bud dormancy; after the need of cold satisfied, different temperature affect flower budburst rate great, constant temperature cause branch sear and death easily, fluctuating temperature and room temperature is good for flower budburst; different hydroponics gradients has no effect on budburst.
