Unlike most of the plant groups previously [http://en.wikipedia.org/wiki/FARP1 FARP1] studied in the Macaronesian region, the lineages of Olea illustrate how low phenotypic differentiation can be also related to a clear molecular differentiation in oceanic island enclaves.?? 2010 The Linnean Society of London, Botanical Journal of the Linnean Society, 2010, 162, 54�C63. ""The germination requirements and the basis of the optimal water content before and after cryopreservation were studied for ten endangered Brazilian species of Bromeliaceae. Constant and alternating temperature regimes were used to determine the best conditions for seed germination. The relationship between seed water content and relative humidity was evaluated using water sorption isotherms at 15?��C. Seeds were cryostored at four water contents (3, 5, 7 and 9%) and three storage periods (0, 180 and 365 days), and loss in viability and vigour were estimated. Fresh seeds of all species showed maximum germination in [http://www.selleckchem.com/products/Adriamycin.html Selleck Doxorubicin] relationship between seed water content and relative humidity was observed with no apparent differences in sorption characteristics among the species. The optimum water content for cryopreservation of most of these species was c. 7%. Ultra-drying (3% seed water content) had a detrimental effect on seed viability and vigour. Our experiments suggested orthodox storage behaviour for all species of Bromeliaceae examined as they are able to survive desiccation and freezing. This study has shown the feasibility of ex situ conservation in seed cryobanks of endangered bromeliads from the [http://www.selleckchem.com/products/obeticholic-acid.html Obeticholic Acid] Brazilian Atlantic Forest to support future reintroduction of these species in nature.?? 2014 The Linnean Society of London, Botanical Journal of the Linnean Society, 2014, 176, 567�C576. ""The critically endangered Synaphea stenoloba (Proteaceae) has numerous scentless flowers clustered in dense inflorescences and deploys a ballistic pollen ejection mechanism to release pollen. We examined the hypothesis that active pollen ejection and flowering patterns within an inflorescence influence the reproductive success (i.e. fruit formation) of individual flowers within or among inflorescences of S.?stenoloba in a pollinator-excluded environment. Our results showed that: (1) no pollen grains were observed deposited on the stigma of their own flower after the pollen ejection system was manually activated, indicating self-pollination within an individual flower is improbable in S.?stenoloba; (2) fruit set in the indoor open pollination treatment and the inflorescence-closed pollination treatment indicated that S.
