摘要:
为了进一步优化无糖组织培养的微环境参数,本研究以青薯9号为供试材料,设置不同梯度蛭石与营养液配比(V蛭石∶V营养液=1.0∶0.7、V蛭石∶V营养液=1.0∶0.8、V蛭石∶V营养液=1.0∶0.9)、CO2含量(500 μmol/mol、800 μmol/mol、1 100 μmol/mol、1 400 μmol/mol)、光照度
[50 μmol/(m2·s)、75 μmol/(m2·s)、100 μmol/(m2·s)]试验,探究各处理对马铃薯组培苗生长发育的影响。研究结果表明,马铃薯无糖组织培养的最适条件为V蛭石∶V营养液=1.0∶0.8,CO2含量800 μmol/mol,光照度75 μmol/(m2·s)。与传统组织培养相比,无糖组织培养得到的马铃薯原原种的产量、数量和成活率分别显著提高16.09%、22.37%和3.27%(P<0.05)。综上所述,本研究结果不仅明确了无糖组织培养的关键技术参数,还证实了该技术在提升马铃薯种薯生产效率方面的优势,为马铃薯组培苗的标准化生产和工厂化繁育提供了理论依据和技术支撑。
Abstract:
To further optimize the microenvironment parameters of sugar-free tissue culture, this study used Qingshu No.9 as the test material and designed different gradient experiments with different ratios of vermiculite to nutrient solution (Vvermiculite∶Vnutrient solution=1.0∶0.7, Vvermiculite∶Vnutrient solution=1.0∶0.8, Vvermiculite∶Vnutrient solution=1.0∶0.9), CO2 concentrations (500 μmol/mol, 800 μmol/mol, 1 100 μmol/mol, 1 400 μmol/mol), and light intensities to investigate the effects of each treatment on the growth and development of potato tissue-cultured seedlings. The light intensity was set at 50 μmol/(m2·s), 75 μmol/(m2·s), 100 μmol/(m2·s). The results showed that the optimal conditions for sugar-free tissue culture of potatoes were as follows: Vvermiculite∶Vnutrient solution=1.0∶0.8, CO2 concentration of 800 μmol/mol, and light intensity of 75 μmol/(m2·s). Compared with traditional tissue culture, the yield, quantity, and survival rate of potato pre-basic seeds obtained through sugar-free tissue culture were significantly increased by 16.09%, 22.37%, and 3.27%, respectively (P<0.05). In conclusion, this study not only clarified the key technical parameters of sugar-free tissue culture but also confirmed the advantages of this technology in improving the production efficiency of potato seed tubers, providing theoretical basis and technical support for the standardized production and industrial propagation of potato tissue-cultured seedlings.
