We characterized the effects of KNO3 pretreatment and germination temperature on dormancy breaking and germination of mature mountain ash seeds. Seeds treated with KNO3 and germinated at 25 ℃ followed by 5 ℃ had significantly higher germination percentages and germination potentials （51% and 49%, respectively）, compared with controls. These treated seeds also exhibited reduced germination initiation times （minimum of 48 days）, and elevated germination rate indices （up to 97）. The germination of seeds subjected to long-term cold storage （2 years at 0-5 ℃） was also significantly improved by 3 days of 4% KNO3 pretreatment before germinating under a variable temperature regimen （5 ℃ followed by 25 ℃, and followed by 5 ℃）. Germination percentages and germination potentials for these cold-stored seeds reached 67% and 54%, respectively, and the germination rate index increased to 126.99. Pretreatment of mountain ash seeds with KNO3 represents a practical, effective, and pollution-free method for improving germination, and can be implemented easily within a variety of nursery settings.

Novel blue light-emitting poly（aryl ether）s comprising of bipolar oligofluorene pendants as chromophores have been designed and synthesized, in which pyrimidine and arylamine moieties are utilized as the electron acceptor and electron donor, respectively. Through varying n bridge length from monofluorene to bifluorene and end-cappers from hydrogen to carbazole and diphenylamine, the emission color of the resulting polymers covers from deep blue to greenish blue, and their HOMO and LUMO levels can be modulated to facilitate charge injection to improve the device performance. Polymer light- emitting diodes （PLEDs） are fabricated with the device structure of ITO/poly（3,4-ethylenedioxythiophene）：poly（styrene sulfonic acid）（PEDOT：PSS）（50 nm）/polymer （80 nm）/Ca （10 nm）/Al （200 nm）. Among these polymers, P2Cz5F-Py with bifluorene bridge and carbazole end-capper shows excellent trade-off between the efficiency and emission wavelength, having a peak luminous efficiency as high as 1.26 cd/A and Commission Internationale de L＇Eclairage （CIE） coordinates of （0.17,0.17）.
