STUDY ON POLLEN NUMBER, POLLEN VITALITY AND BLOOMING TIME OF SOUR JUJUBE (ZIZIPHUS ACIDOJUJUBA C.Y. CHENG ET M.J. LIU)

Q.H. Shi, P. Liu, Z.H. Zhao, M.J. Liu
Pollen number and pollen vitality of different sour jujube genotypes were studied by using blood-cell counter and TTC staining method and flower bud cracking time were also observed. The results showed that most of the sour jujube genotypes have large pollen number and strong pollen vitality. ‘Sour jujube K’ could be used a suitable female parents for it has both low pollen quantity and poor pollen viability. Their blooming time widely range from 4:30 in the morning to 17:00 in the afternoon.
