Abstract:The DPH fluorescent probe (1,6-diphenyi-1,3,5,-hexatriene) was used to study the 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℃ 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 seed. | |||

Abstract:Ceratoides arborescens seeds were tested for the effects of aging-resistance and free radical scavenging following seed ultradry. The results indicated that: (1)Ultradried seeds under the conditions of certain moisture content showed no adverse effect on seed vigor. Furthermore, ultradried seeds significantly enhanced aging-resistant capability under aging-accelerating condition (45℃, 2 days). The critical moisture content for Ceratoides arborescens seeds was about 3.78%. (2) Activities of the antioxidant enzymes including catalase and superoxide dismutase were reserved during storage in an ultradry state. (3) During ultradrying of Ceratoides arborescens seeds, the level of free radicals increased, but decreased as prehumidification before imbibition, which had a scavenging action on free radicals. | |||
