It was found that a slide centrifuge (Cytospin) preparation of a cell suspension allowed a reliable assessment of not only cell structure but also the percentage of non-viable cells. The non-viable cells appeared as "smear" cells and paralleled in number the cells taking up trypan blue. Direct experiment showed the unstained viable cells in a trypan blue cell suspension remained intact in a Cyt...

Viability of fresh and stored pollen of date palm (Phoenix dactyllf.,.., L) was studied. Pollen samples were stored at room temperat. ture (25-30°C), under refrigeration (3-4°C)t..ln vivo test, pollen viability was determined'by percent fruit set. Results suggest that different storage conditions had no apparent effect on pollen viability as tested with acetoearmine. However, results of in vivo...

Studies were made to determine how long Douglas-fir pollen remains viable after suspension in cool water from 0 to 34 days. Linear regression analysis of in vivo and in vitro tests indicated that filled seed efficiency and pollen viability, respectively, decreased about 3 percent per day. The relation may have been nonlinear the first 6 days, as little decrease occurred during that time. An in ...
