Abstract

Germination rate of Phoebe bournei seed in the field is an index to evaluate seed vigor .The seeds artificially aged (38 ℃, 100 %RH, 72 h)and seeds not artificially aged are used as different materials for vigor testing to find some reliable methods to determine the seed vigor of Phoebe bournei simply and quickly for production .Electric conductivity method , tetrazolium method and germination physiological method are adopted in the research .The results show that the non-aged seed has a higher vigor than the aged seed was low .The results corresponded to the germination rate in the field .Therefore , these methods can be used to determine the seed vigor of Phoebe bournei .Electric conductivity method and tetrazolium method are simple and quick and their results are reliable ;while germination physiological method takes a long time , but its result is intuitional and accurate .[ Ch , 4 tab .5 ref .]
