Abstract

Abstract: Effects of low temperature,high temperature,sugar-free,colchicines and mannitol pretreatment were studied on the survival rate of microspores in 4 radish cultivars.The result show that microspores had high survival rate under 4℃ after 3 days treatment,while 36℃ treatment reduced the survival rate.The media with sugar,mannitol and colchicines enhanced the vigor of microspores.And the concentrations of mannitol and colchicines had different effects on 4 radish cultivars.

Key words: Radish, Pretreatment, Survival rate of microspores
