Abstract The paper studied watermelon〔Citrullus lanatus(Thunb.)Matsum. et Nakai〕pollen
cryopreservation methods and pollination technique.The result indicated that pollens of‘ Zaojia’ watermelon
can be stored at -18 ℃ or -25 ℃ under vacuum condition for 186 to 223 days with over 50% activity.
Pollen activity can be varied under different storage conditions,of which -25 ℃ can have longer
storage time than -18 ℃,and the pollen vitality is higher.The stored pollens should be activated at 25
℃ for 30 min before usage,so as to achieve higher fruit setting rate.The application of stored pollen
will not influence the quality of watermelon.
