为研究怀地黄(Rehmannia glutinosa)脱毒种苗大田生长、产量和品质状况,对大田中不同时期脱毒苗和非脱毒苗的形态指标、生理特性、光合特性、产量及品质等进行了测定。结果表明,脱毒苗的株高、冠幅、叶片数、最大叶面积、功能叶片的光合色素含量和净光合速率等各项指标均优于非脱毒苗,块根产量提高、品质改善,增产幅度在77.35%以上,药用成分梓醇含量提高了32.90%。
In order to study the field growth, yield and quality of detoxified seedlings of Rehmannia glutinosa, the morphological characteristics, physiological characteristics, photosynthetic characteristics, yield and quality of virus-free and non-virus-detoxified seedlings in field were determined . The results showed that the indexes of plant height, crown width, number of leaves, maximum leaf area, photosynthetic pigment content and net photosynthetic rate of virus-free leaves were better than those of non-virus-free seedlings, yield of tuberous roots improved, quality improved, Amplitude of 77.35% or more, the medicinal composition catalpol content increased by 32.90%.
