月季一般采用扦插、嫁接、压条等方法繁殖,但一些名贵品种扦插不易生根,且由于数量极少,大量快速繁殖受到一定限制。 1982年以来,常州园林管理处、江苏省林业科学研究所用组织培养方法快速繁殖月季,大大提高了繁殖系数,先后诱导出名贵月季“红双喜”等五十余种,提供试管苗十余万株。月季花组织培养的工艺流程●取材与消毒取健壮优良母株的嫩茎,剥去腋芽上的嫩叶,将材料放在流水中冲洗,随后移到无菌室超净工作台上进行消毒。先浸入70%酒精中0.5~2秒钟,再在0.1%升汞中消毒5~8分钟,取出材料用无菌水冲洗4~5次。将嫩茎的茎段切成0.5~1.0厘米长,接种在固体培养基上,诱导腋芽萌发。培养条件:白天20~25℃、夜间15~20℃,每日光照10小时,光强为1000勒克斯。
Roses generally use cutting, grafting, pressure strips and other methods of breeding, but some rare varieties of cutting is not easy to root, and because of the small number of large-scale rapid propagation subject to certain restrictions. Since 1982, Changzhou Garden Management Office and Jiangsu Provincial Institute of Forestry have rapidly propagated the rose with tissue culture method, greatly raising the breeding coefficient and successively inducing more than 50 species such as the “Double Happiness” of the precious rose, providing more than 100,000 test-tube seedlings. Rosa sinensis tissue culture process ● drawing and disinfection take sturdy good mother plant stems, stripped axillary buds on the leaves, the material in the running water rinse, and then moved to the clean room clean bench disinfection. First immersed in 70% alcohol for 0.5 ~ 2 seconds, and then sterilized in 0.1% mercuric chloride for 5 to 8 minutes, the material was washed with sterile water 4 to 5 times. Stem section of the tender stem cut into 0.5 to 1.0 cm long, inoculated on solid medium to induce axillary bud germination. Culture conditions: day 20 ~ 25 ℃, night 15 ~ 20 ℃, daily light 10 hours, the light intensity of 1000 lux.
