The invention relates to a tissue culture method for callus of callus, including explant disinfection, induced culture and callus preservation. In the process of callus culture of callicum, there are many problems such as browning and death of callus. When we discuss the preservation methods of callus of Penicillium, we use this inventive callus preservation medium to improve MS+0.2 ~ 0.8mg/L 6 BA+0.05 ~ 0.2mg/L NAA+30g/L sucrose +7g/L agar, pH 5.8. The results showed that the multiplication factor of the callus was 4.80 times, the browning rate was 0%, the callus grew well, the propagation speed was fast, and the death of the callus did not occur. The invention successfully solves the problems of browning and death of the callus tissue, difficult to subculture and preserve, and has strong practicability and good generalization.

青钱柳愈伤组织保存组培方法
本专利技术涉及一种青钱柳组织培养方法,具体涉及一种青钱柳愈伤组织保存组培方法。
技术介绍
青钱柳(Cyclocaryapaliurus(Batal.)Iljinskaja),又称为青钱李、摇钱树,属于胡桃科(Juglandaceae)青钱柳属,不仅是我国独有的单种属乔木植物和国家重点保护二级濒危植物之一,也是集观赏、造林、药用、材用等多种用途的珍贵且经济树种。目前,青钱柳栽培主要是依靠种子繁殖,但具有深休眠特性的种子在播种后需隔年甚至2年后才能萌发,且种子空籽率高,仅有0.1-0.2%发芽率,出苗率不一致,这些导致青钱柳自然繁殖效率低,限制了青钱柳的栽培效率和推广。因此,迫切地需要一条高效的青钱柳培养途径。组织培养是青钱柳无性繁殖的有效途径,随着组织培养技术的发展,青钱柳离体培养研究也越来越受到关注。以叶片、茎尖、茎段等外植体进行离体培养时,均可诱导出愈伤组织或丛生芽(不定芽)。但是,青钱柳组织培养过程中,尤其是愈伤组织培养时,外植体和愈伤组织存在严重地褐化问题,使得在继代培养或增殖培养过程中愈伤组织繁殖系数不高、难保存,甚至死亡。可见 ...
