Abstract: (8325 Views)
Aim and Background: Capparisspinosa L. is considered as one of the most significant plant species in the capparaceae. This plant is one of the most important medicinal plants and has a great ability to stabilize sand dune. Seeds of this plant have germination problems. The aim of this research is to determine germination percentage of Capparisspinosa according to different duration of chilling (0, 10, 20, 30, 40, 50, 60, 70 and 80 days) and temperature (1-4, 7-9 c).
Materials and Methods: Cold stratification procedures under in-vitro condition were applied for eliminating seed dormancy to find the most suitable germination conditions because the presence of seed dormancy causes difficulties in seedling production. In order to break seed dormancy, this experiment has been in the base of completely Randomized Design in 3 replications
Results: Data analysis showed that the highest germination percentage (69.91%) was obtained in seeds that were in concentrated sulfuric acid for 30 minutes before being in cold stratified condition for 60 days, in1-4c, the lowest germination percentage (2.86%) was determined in control seeds
Conclusions: Based on these results, the application of chilling and chemical treatment on seed dormancy of Capparisspinosa is very important and effective on defecting seed dormancy, which can affect the economical importance of this species
