Effects of Different Temperature Treatments and Storage Time on Seed Germination of Acacia cincinnata
To explore the germination state of Acacia cincinnata seeds in different storage time under differ-ent temperature treatments.Three kinds of A.cincinnata seeds stored for 4,2 and 0 years(the current year without storage)were used as experimental materials.The germination rate,germination potential,germination index,radicl length and biomass of the seeds were analyzed after soaking for 24 hours at different temperatures of 25,40,60,80,100℃.The results showed significant differences(P<0.01)in A.cincinnata seeds germi-nation indexes under different temperature treatments.The germination rate,germination potential and germina-tion index of seeds collected at 100℃in the same year were the highest,which were 73.2%,47.2%and 7.32,respectively.Overall,the seed germination rate,germination potential and germination index increased with the increase of temperature and decreased with the extension of storage time.The best seed germination effect was obtained when the seeds were collected in the current year and treated at 100℃water temperature for 24 hours.
