Effect of Desiccation on Germination of Larix kaempferi Embryoids
[Objective]To improve the germination ability of Larix kaempferi embryoids and optimize the breeding technology of Larix kaempferi.[Method]In this study,we conducted classification on embryoids based on the number of cotyledon and the hypocotyl shape.Subsequently,their germination rates were re-corded respectively.The germination rate of typeⅠembryoids was evaluated after desiccation using"pa-per vessel method".[Result]Type Ⅰ embryoids exhibited an initial germination rate of 5%,while the re-maining types did not show any germination.However,after drying for two weeks,the germination rate of type Ⅰ embryoids significantly increased to 69.43%,and embryoids with desiccation response were more likely to germinate.[Conclusion]These results show that the germination rate of Larix kaempferi em-bryoids is significantly improved after desiccation,which provides insights into new strategies for improv-ing seedling production for this species.
