The present invention discloses a kind of tissue culture and rapid propagation of leeks, including leek seed pretreatment, leek seeds sterilization, aseptic seedlings and cotyledon, stem and root explants preparation and callus and bud induction, rooting and acclimatization. In the invention, no vaccine with leeks from cotyledons, stems and roots were successfully induced to differentiate into regeneration, which greatly improves the utilization rate of sterile seedlings of each part, significantly improve the regeneration frequency of the explants, laid a solid foundation for the micropropagation of leek. In the process of transplanting with sawdust as matrix during water irrigation treatment method greatly improves the survival rate of the moisture of the leek regeneration seedling breeding, in order to ensure the rapid propagation of tissue culture provides a strong guarantee of leek.

一种韭葱组织培养快速繁殖的方法
本专利技术涉及一种韭葱组织培养快速繁殖的方法。
技术介绍
现有的韭葱组织培养繁殖系数低、植株成活率低,需要进一步加以改进。
技术实现思路
本专利技术的目的在于提供一种提高无菌苗各部分的利用率、提高了外植体的再生频率、提高韭葱再生植株移栽成活率的韭葱组织培养快速繁殖的方法。本专利技术的技术解决方案是:一种韭葱组织培养快速繁殖的方法,其特征是:包括下列步骤:(1)韭葱种子的预处理韭葱品种为Musselburgh;挑选大小一致、圆润饱满的优质韭葱种子,自来水冲洗干净后将种子浸泡在50mg/L的GA3溶液中24h,然后置于25℃的光照培养箱中遮光培养一天备用;(2)韭葱种子的消毒灭菌取出上述种子,用超声波清洗机清洗2-3min,再用无菌水冲洗2-3次,然后用75%的酒精消毒35-40秒,接着用无菌水冲洗1-2次,再用0.1%的升汞消毒5-6min,最后用无菌水冲洗3-4次;(3)无菌苗的获得将消毒灭菌后的种子接种在MS培养基上,先25℃黑暗条件下培养,待大多数种子露白后移到组培室光下继续培养,获得无菌苗;(4)子叶、茎段、根段外植体的制备取韭葱无菌苗,剪成0.5cm大小的子叶、茎段和根段,任其自然下落到培养瓶内的培养基上,剪取结束后,用镊子将外植体均匀摆放在培养基上进行培养;(5)愈伤组织和芽的诱导韭葱子叶、茎段和根段愈伤组织和芽的诱导培养基均为MS+6-BA1mg/L+2,4-D0.2mg/L,蔗糖和琼脂浓度分别为30g/L、8g/L;上述外植体培养15d,在切口边缘处形成大量的乳白色愈伤组织;随着培养时间的推移,乳白色愈伤组织上形成 ...
