林木组织培养,是现代科学研究领域中的一项新技术,国内外正广泛进行研究试验,有的已取得良好成效。为加速繁育优良林木,我们对滇杨、美洲红杉等八种林木进行了组织培养研究,现已诱导出滇杨、美洲红杉的完整植株。用滇杨约20年生大树的嫩叶片、嫩枝、生长点和五年生美洲红杉的嫩枝、萌条或其生长点,作试验材料,接种前,将试材放入24%的双氧水(过氧化氢)中浸泡8分钟,作表面消毒,取出用无菌水冲洗三次,然后在无菌条件下,将试材切成约0.5厘米长的小段,接种在配制好的培养 Forest tissue culture is a new technology in the field of modern scientific research. Research experiments are widely carried out at home and abroad, and some have achieved good results. In order to accelerate the breeding of excellent trees, we conducted tissue culture studies on eight kinds of trees, such as Populus davidiana and Sequoia, and now we have induced complete plants of Populus davidiana and Sequoia. Young leaves of about 20-year-old Populus euphratica, shoots, growing points and five-year-old Sequoia shoots, sprouting or growing point for the test material before inoculation, the test material into 24% hydrogen peroxide (Hydrogen peroxide) for 8 minutes for surface disinfection, remove and rinse with sterile water three times, and then under sterile conditions, the test material is cut into small pieces of about 0.5 cm long, inoculated in the prepared culture
