METHOD: Life Cycle CONDITIONS: Green House - 14h light at 36-43C (hot) or 16-24C (temperate) METHOD NARR: In 1992 species were planted in GHs under either temperate or hot temperature regimens. At the start of the regimen, allt were removed from plants in both environments. Pollen was collected at the end of each of the following three weeks. This trial focused on pollen production which was scored subjectively and stained for viability. Anothe see separate entry. RESULTS NARR: Pollen production (Shed) was scored subjectively from 0-5 with 0=no pollen and 5=abundant pollen. Viability was assessed as % stained pollen (PSP) of 500 grain samples. Shed scores in them and high. Shed scores in the hot house were poor across all accessions. PSP scores in the temperate house were uniform and high with an average of 85%. In the hot house, the average was 33%.
