Study on the Method of Measuring Pollen Viability and Pretreatment of Pollen

Method of measuring pollen viability and pretreatment of pollen have very important significance for artificial pollination.Taking Actinidia chinensis as materials,the best way of measuring pollen viability and the effect of different treatments were studied.The results showed that,for pollen of flower bud,the method of TTC,the pollen viability was low,and the method of germination in vitro and the pollen viability was high.So,the best way of measuring pollen viability was methods of staining and germination.The rate of pollen germination was associated with the time,and for flower bud,the best way was separation of stamens and petals immediately for improving the rate of pollen germination;Pollen drying was associated with environmental condition,if the environment was suitable for drying pollen,it didn't need to use other drying methods.
