- 摘要:
- 为提高马铃薯组培苗品质,本试验以兴佳2号、克新13为试材,以白色荧光灯为对照,采用LED光源,研究红光、蓝光、红蓝组合光(5∶5)对马铃薯组培苗叶绿素a、叶绿素b、类胡萝卜素和总叶绿素含量的影响。结果表明:蓝光光照培养和红蓝组合光(5∶5)培养均能提高马铃薯叶绿素a、类胡萝卜素和总叶绿素含量,其中蓝光处理提高效果更为明显;红光处理会降低马铃薯叶绿素a、叶绿素b、类胡萝卜素和总叶绿素含量;红蓝组合光(5∶5)、蓝光和红光均能降低马铃薯叶绿素b含量,其中红光处理降低幅度最大,其次是蓝光处理。研究表明蓝光与红蓝组合光光照培养更有利于马铃薯组培苗光合色素的合成。
- Abstract:
- In order to improve the quality of potato tissue culture seedlings,this experiment took Xingjia 2 and Kexin 13 as test materials,fluorescent lamp as control and LED light source to study the effects of red light,blue light and red-blue combined light(5∶5)on the contents of chlorophyll a,chlorophyll b,carotenoid and total chlorophyll in potato tissue culture seedlings.The results showed that the contents of chlorophyll a,carotenoid and total chlorophyll in potato were increased by blue light and red blue combined light(5∶5),and the effect of blue light treatment was more obvious.The contents of chlorophyll a,chlorophyll b,carotenoid and total chlorophyll were decreased in red light culture.Red and blue light(5∶5),blue light and red light all reduced potato chlorophyll b content,and red light treatment had the largest reduction,followed by blue light treatment.Therefore,the combination of blue light and red blue light was more conducive to the synthesis of photosynthetic pigments in potato tissue culture seedlings.
