试验研究室外栽培条件下,利用不同占空比的脉冲光源对工业大麻进行补光,探究其对工业大麻生长发育、生理生化以及主要大麻素含量的影响.结果表明:占空比 100%(LED1)和占空比70%(LED2)的光源促进了工业大麻株高、茎粗、SPAD值以及花叶干重和鲜重的增加,但LED2 与不补光(CK)差异不显著,而占空比 50%(LED3)光源显著降低了工业大麻的株高、茎粗、SPAD值以及花叶干重和鲜重;LED1、LED2 和LED3 提高了工业大麻叶片中可溶性糖、可溶性淀粉以及游离氨基酸的含量,LED1 与CK差异显著,LED2 和LED3 与CK差异不显著;LED1 和LED2显著降低了超氧化物歧化酶(SOD)、过氧化物酶(POD)和过氧化氢酶(CTA)活性,而LED3 显著促进抗氧化物酶(SOD、POD和CTA)的活性;LED1 显著降低了四氢大麻酚(THC)和大麻二酚(CBD)的含量,而LED1、LED2 和LED3 显著提高了大麻萜酚(CBG)的含量.LED1 和LED2 光源均可以促进工业大麻的生长发育,增加可溶性渗透调节物质含量,降低抗氧化物活性,增加CBG含量,为今后利用节能(占空比)脉冲光源提高工业大麻品质和产量提供理论参考.
Effects of Different Pulsed Duty Cycle on the Growth,Physiological and Biochemistry of Industrial Hemp
To explore the effects on the growth,physiology and biochemistry and main cannabinoid content of industrial hemp,different pulse duty cycle light was used to filled light for industrial hemp un-der outdoor cultivation conditions.The results showed that the light source with duty cycle ratio of 100%(LED1)and 70%(LED2)promoted the increase of plant height,stem diameter,SPAD value and dry and fresh weight of flowers and leaves for industrial hemp;there was no significant difference between LED2 and no filling light(CK);the light source with duty cycle ratio of 50%(LED3)significantly re-duced plant height,stem diameter,SPAD value and dry and fresh weight of flowers and leaves of indus-trial hemp.LED1,LED2 and LED3 promoted the contents of soluble sugar,soluble starch and free ami-no acids on industrial hemp leaves,and there was significant difference between LED1 and CK,but no significant difference between LED2 and LED3 and CK.LED1 and LED2 significantly reduced the activi-ties of superoxide dismutase(SOD),peroxidase(POD)and catalase(CTA),while LED3 significantly promoted the activities of antioxidant enzymes(SOD,POD and CTA).LED1 significantly reduced tetra-hydrocannabinol(THC)and cannabidiol(CBD)levels,while LED1,LED2 and LED3 significantly promoted cannabinol(CBG)levels.Both LED1 and LED2 light sources could promote the growth and development of industrial hemp,increase the content of soluble osmoregulatory substances,reduce the antioxidant activity,and increase the content of CBG.The result of this study is a theoretical reference for improving the quality and yield of industrial hemp by using pulse light sources in the future.
