Abstract

The pollen viability were tested by means of TTC , inorganic acid and germination in vitro .The results showed that only when in vitro mediumwas added PEG , the pollen germiation rate could be improved and represent the pollen viability .The best molecularweight and cocentration of PEG for germination were 6 000 and 300 gkg-1respectively .The effect of the medium of 300 gkg-1 PEG 6 000 and 100mgL-1H3BO3 on pollen germination was the best in this test .The cultivars of Chimonanthus praecox were different in pollen viability .The life-span of pollen in room condition was 18 to 19 d , and was about 2 months in cold storage (4 2)℃.[ Ch , 3 fig .2 tab . 11 ref .]
