Abstract

Abstract: To lay a foundation for the development of artificial cultivation of Seseli mairei Wolff and the restoration of wild resources, this research was carried out on the biological characteristics of S. mairei Wolff seeds. Firstly, the method of symptom observation and weighing was used to describe the seed characteristics and measure the thousand grain weight of the seeds to obtain the characteristics of good seed and thousand grain weight. Secondly, 4 temperature gradient treatments were set to observe seed germination potential and germination rate and determine the most suitable germination temperature. The most appropriate treatment concentration was to observe the germination rate. Finally, the Chinese cabbage seeds were treated with the extract of S. mairei Wolff seeds to observe its inhibitory effect on seed germination and determine whether there existed substances in seeds that would inhibit germination. Moreover, S. mairei Wolff seeds were soaked in four concentration gradients of GA3 solution to observe their germination rates for further selection of the most optimal treatment concentration. S. mairei Wolff seed has the weight of 1.0 g and the most suitable germination temperature is 30℃, with inhibition of germination substance. Additionally, use of 100 ppm GA3 can improve seed germination rate. S. mairei Wolff is a high temperature germination seed with inhibitory substances, and effective measures should be taken according to the biological characteristics of the seed in order to improve the seed germination rate.

Key words: Seseli mairei Wolff, seed, characteristic, dormancy, germination
