摘要

The DPH fluorescent probe (1, 6-diphenyi-1, 3, 5,-hexatriene) was used to study the effects of ultradry seed storage on the fluidity of plasma membrane. Results indicated that the micro-viscosity of plasma membrane of ultradried seeds had no significant changes compared with the Haloxylon persicum seeds which were stored under 4°C condition. However, there was a little adverse effect on the seeds with extreme dehydration. The results were consistent with higher vigor level of ultradried seed. It indicated that ultradry seed storage could maintain the physiological function of seed, protect the integrity of the membrane and improve the storability of seeds.
