Seed morphology and micrographs of seed surface and shape of <I>Vaccinium arctostaphylos</I> L. prepared using Scanning Electron Microscope (SEM) studied in this experiment. To evaluation of Qare-Qat seed dormancy and assessment of the best conditions for seed germination, the experiment carried out using factorial design with three factors in three replications in RCBD. Factor A was seed chilling period in four levels (15-90 days), Factor B was chilling conditions in two levels (wet and dry chilling) and factor C was germination conditions in two level too (germination in absolute dark and germination in light and darkness alternation). Results showed that the seeds of ripened fruits were not similar size and they are seen from minute to tiny size. Electron micrographs showed that Qare-Qat seeds are ovate or elliptical. Germination conditions test showed that seeds after expire of dormancy period could only germinate in light and darkness alternation and they could not germinate in absolute darkness. Therefore, Qare-Qat seeds had positive photoblastic reaction. Seed dormancy |
