摘要
Abstract
It is important link to understanding the pollen viability of jicama for crossbreeding.The results indicated that there were significantly differences for the pollen viability of jicama measured by methods of culture in vitro,TTC and I2-KI.For the same viability pollen,the pollen viability was within 36％ by culture in vitro,while the pollen viability was more than 92％ by I2-KI.There were also differences in the pollen viability of different varieties by the same test method.The pollen germination result was the best when the pollen cultured for 5 ～ 6 h in vitro with 20％ of sucrose,10 mg/L of boric acid,pH 7.22.The staining time of I2-KI was the fastest and dyeing deeply,its appropriate concentration was 0.5％.关键词
