Effect of different seed priming treatments on dormancy and seed germination characteristics and heterotrophic growth of kelussia seedling and assess its compatibility with the climatic conditions of Boroujerd

Mountain Kelussia is one of the endangered species that in order to prevent the extinction of this valuable plant, it is necessary to protect its natural resources and make efforts to rebuild the damaged pastures. This requires the study of germination failure germination of seeds of this plant. The seeds of the mountain kelussia plant have dormancy, which reduces their vigor. This study was performed to investigate the effect of different sleep failure treatments on germination and seedling growth of kelussia. The experiment was conducted as a completely randomized design with four replications. Experimental treatments include potassium nitrate , gibberellic acid ppm, gibberellic acid ppm, gibberellic acid ppm, smoke treatment, hot water treatment in C, leaching treatment, temperature treatment of ° C , Temperature ° C, temperature ° C, temperature ° C for , , and weeks, scratching treatment and control treatment. The results showed that the effect of dormancy treatment on all characteristics related to germination and seedling growth of kelussia was significant. The results also showed that none of the treatments except seed storage treatment at ° C resulted in germination of kelussia seeds. With increasing the storage time of kelussia seeds at ° C, germination percentage, root length and dry weight, shoot length and dry weight, seedling length and dry weight, seed vigor and seedling also increased. In general, the results of this study showed that the best treatment to eliminate seed dormancy of kelussia seeds and seedling growth is to store watered seeds in cold conditions for weeks. The result of evaluating the compatibility of kelussia seedlings showed that it has grown in Boroujerd region and has the ability to adapt to this region.
