Possibility of Improving Caper (Capparis Spinosa L.) Seed Germination as an Ornamental Cover Plant Using Combined Methods of Dormancy Removal

The aim of this study was to investigate the effect of different treatments of seed dormancy failure and improved germination of Caper seeds (Capparis spinosa L.).

The experiment was conducted in the form of a completely randomized design at the University of Tabriz in 1398. The treatments used in this experiment include leaching treatment at 40 ° C for 12 hours, scarification treatment and chilling treatment (in a cool (4-5⸰C) and wet place for two weeks and one months). It was applied to Caper plant seeds in different treatment combinations in laboratory conditions.

characteristics such as germination percentage, seed vigor index, seed germination rate, first day of germination, plant height and leaf emergence time were recorded and compared in each treatment. All characteristics were statistically significant at the level of one percent. The best treatment in all germination and growth characteristics of the plant was combined treatment of one month cold with seed scarification.

In general, The Mechanical scarification of seeds with combined treatment of one month cold has a more favorable effect than treatments with two weeks and without seed scratching. Therefore, increasing the cooling time had a positive effect on this experiment. Increasing the cooling time is more effective in eliminating seed dormancy and germination rate, and also seed leaching increases plants height.
