Seed priming technology;Sugar beet;Paper-pot seedling;Germination rate

In order to promote seedling quality of sugarbeet in paper-pot,the experiment was carried out in Jiusan,Nehe and Hailun.Using the seeds of 'Bastion' and 'Acero' treated by priming technology(XBEET) and the seeds of 'Bastion' and 'Acero'without any treatedent(CHECK,as the controls) as the testing materials.The experiment used the method of seedling in plastic-film greenhouse to study the seedling status.The results showed that the seedling status time and sprouting peak of XBEET were two days earlier than CHECK's.The germination rate of XBEET increased by 2.50%-15.00%,daily average germination percentage increased by 4.48%-74.42%,the germination index increased 1.81%-5.20%.The fast emergence of the seedling XBEET was beneficial to arrive seedling even as soon as possible and was beneficial to manage the seedbed in paper-pot and to promote the seedling quality.
