“…Seed dormancy can be overcome by different presowing dormancy-breaking treatments such us dry heat treatment, hot water treatment, mechanical scarification, chemical scarification, stratification and treatment with growth regulators (Phuyal et al, 2022). Physical, mechanical and chemical treatments reduce exogenous seed dormancy by removing or permeabilizing the seed coat, while stratification and treatment with growth regulators reduce endogenous seed dormancy by neutralizing seed germination inhibitors (Lavallee et al, 2021).…”

Vine-leaved kitaibelia (Kitaibela vitifolia Willd.), also known as balkanmalva or chalice flower, is a critically endangered plant species with a high risk of extinction in the wild. A reason given for this is, among others, a low germination rate primarily caused by dormancy. The present study evaluated the seed germination and seedling growth parameters of vine-leaved kitaibelia in response to eight different pre-sowing treatments. The final germination percentage ranged from 0 % to 55 %, depending on the pre-sowing treatment. The most effective method for breaking dormancy and increasing vine-leaved kitaibelia seed germination was the treatment with seeds soaked in H2SO4 for 5 min. The mechanical scarification of vine-leaved kitaibelia seeds also improved germination as compared to control treatment, while treatments with nitric acid and gibberellic acid were not effective in enhancing seed germination. All evaluated seedling growth parameters were not affected by pre-sowing treatments. Considering that successful germination and seedling establishment are crucial for the regeneration of vine-leaved kitaibelia further studies are required in order to identify other pre-sowing treatments that could further enhance seed germination and, consequently, seedling development.

Rootstock preparation from seed is the prerequisite for fruit crop multiplication through grafting or budding, and hard seed coat in jujube has been the proven question for uniform seed germination and subsequent seedling growth. Therefore, the study aimed at successful and rapid production of uniform and healthy jujube rootstocks through applying mechanical seed priming at the presowing stage. The experiment was set in a randomized complete block design where scrapped seeds, cracked seeds, seed kernels, and intact seeds (control) were sown in polybags keeping five replications. The emergence and initial seedling growth were evaluated to sort out the best pretreatment methods for successful stock seedling production in jujube. Seed cracking resulted in the highest germination (69.00%) compared to other pretreatments and also showed better performance in respect of earliness of emergence (10.40 days (d) for the first emergence and 20.40 d for final emergence). Regarding the early plant vigor, significantly maximum seedling height (23.73 cm) and fresh (3.91 g) and dry weight (1.17 g) of seedling and the second‐best leaf number (14.24 seedling−1) were also noted in seed cracking. Although seed kernel had the fastest emergence in 7.20 d, and statistically similar seedling vigor with that of cracked seed but it possessed very low germination percentage (27.00%) compared to the best treatment. Meanwhile, seed priming by scrapping exhibited statistically inferior germination rate (32%) as of intact seed (21%), and below par seedling growth compared to cracked seed. So, seed pretreatment by cracking can be suggested for commercial stock plant regeneration in hard seed‐coated plant species.
