Abstract: This is one of the serial reports of studies of the main food bamboo for panda. This paper deals with the seed-store methods of Fargesia nitida and Fargesia denudata through different time、location、climate、tool、seed-dressing varied medicines and chemicals ⁶⁰Coγ rays. For 462 days, the experiment has been carried out 5 times treated in 46 groups with 18400 grains of seed. The results show that store-time is appropriate not more than one year, and the arid and cold location over 2500 metres above sea level is a good choice. Store-seeds can be stored in tile jar with quicklime (about 5% of seed weight). The moisture of seeds should be keeped in 6—11%. The seeds mixed in thiophanate-methyl、parathion methyl、parathion depterex methyl (about 0.6% of seeds weight) or radiation treatment dealt with ⁶⁰Coγ rays (1000 roentgen) than mixed with zinc sulfate (50ppm), the rate of germination is increased by 16—24.6%. Especially it can prolong seed life.
